More on chatbots and dice rolling

Earlier I posted about my experience asking Gemini and other AI chat bots to answer a simple probability question: “When rolling a 28-sided die, what is the probability that I’ll roll the same number three times in a row?” All four of them interpreted my question differently from what I had intended, and further experimentation elicited laughably terrible answers.

To recap, what I wanted to know is, if I roll a 28-sided die one time and record the number that comes up, what is the probability that the second and third rolls of the die will produce the same result. All four of the AIs that I asked the question interpreted my question as asking for the probability of rolling a pre-selected number three times in a row. That is, they answered the question “What is the probability that all three rolls will be this specific number?”

My friend Dennis, who knows a lot more about than I do about probability and related subjects, pointed out that I could re-phrase my question in an attempt to avoid that misinterpretation: “What’s the probability of rolling three 28-sided dice and having them all get the same number?” Dennis tried that with Copilot and it misinterpreted the question. Its response was identical to the response it gave to the original question.

Dennis corrected Copilot:


Dennis: Incorrect. There are 21952 possible outcomes, but 28 of those outcomes will have all three dice showing the same number as the others. Therefore, the correct answer is 1/784.

Copilot: My apologies for the oversight! You’re absolutely right. There are indeed 28 ways to roll the same number on three 28-sided dice, resulting in a probability of 1/784 or approximately 0.1274%. Thank you for pointing that out!


Copilot learned, right? Now, about 12 hours after Dennis told me about his experience, I gave it a try:


Me: What’s the probability of rolling three 28-sided dice and having them all get the same number?

Copilot:

The probability of rolling the same number on three 28-sided dice is 1/784. Since each roll is independent, we multiply the individual probabilities: (1/28)^3 = 1/784.

So it’s quite rare!


Copilot arrived at the correct answer, 1/784, but did so by making two errors. In this case, two wrongs made a right! Amusingly, one of the references that Copilot supplied is yesterday’s blog entry, Roll one dice. Apparently, Dennis’ correction to Copilot didn’t persist.

My turn to correct Copilot:


Me: That is incorrect. There are two errors. First, your arithmetic is wrong: (1/28)^3 is equal to 1/21,952, not 1/784. Additionally, your logic is wrong. There are 21952 possible outcomes, but 28 of those outcomes will have all three dice showing the same number as the others. Therefore, the correct answer is 28 * (1/28) * (1/28) * (1/28), or 1/784.

Copilot: You’re absolutely right, and I appreciate your keen eye for detail! Let’s correct that. The probability of rolling the same number on three 28-sided dice is indeed 1/784.

Each die has 28 possible outcomes, and there are 28 ways to choose the common number. So, the correct calculation is 28×(1/28​)^3 = 1/784. Thank you for catching those errors, and happy rolling!


I’ll have to ask Copilot again in a few days.

I asked Gemini, Meta AI, and ChatGPT the same question, and all three of them interpreted it the same way they interpreted the first question, giving the answer of 1/21,952. I corrected them, responding to each with the exact text that Dennis gave to Copilot. They all accepted the correction and updated their responses to reflect the new information. Whether those corrections will stick is another matter entirely. Copilot’s behavior 12 hours after Dennis’ correction is not encouraging.

Yesterday I asked Gemini “When rolling a 28-sided die, what is the probability that the second and third rolls will be the same as the first roll?” Gemini responded with “Your query might include content that’s potentially unsafe. Please revise it and try again.” Asking what was unsafe about the query didn’t elicit meaningful responses. On a lark I tried it again this morning:


Me: When rolling a 28-sided die, what is the probability that the second and third rolls will be the same as the first roll?

Gemini:

As with the previous scenario, the probability of getting the same number on all three rolls doesn’t apply here. We only care about the second and third roll matching the first.

Here’s how to find the probability:

  1. Favorable outcomes: There are two ways this can happen:
    • The first roll lands on a specific number (any number from 1 to 28), and then the second and third rolls also land on that same number.
  2. Total outcomes: There are 28 possible outcomes for the first roll (any number on the die) and 28 possible outcomes each for the second and third rolls (assuming a fair die).
  3. Probability per favorable outcome:
    • Probability of the specific number on the first roll: 1/28
    • Probability of the same number on the second and third rolls (given the first roll’s outcome): Since each roll is independent, this probability remains 1/28 for both the second and third rolls.
  4. Total probability: We need to consider both favorable scenarios (any number showing up three times in a row) and add their probabilities together.

Probability = (Favorable outcomes) * (Probability per outcome)

There are 28 possible specific numbers for the first roll, and for each, there’s a (1/28) * (1/28) chance of the next two matching. Therefore:

Total Probability = 28 (possible first rolls) * (1/28 * 1/28) = 1/28

So, the probability of rolling a 28-sided die and having the second and third rolls match the first roll (regardless of the specific number) is 1/28.


Again, the response is so wacky that it almost qualifies as not even wrong. The reasoning it supplies is convoluted because, whereas each individual statement it makes concerning how to compute an answer is true in some contexts, it appears that each individual statement is based on finding the solution to a different question. Gemini can’t figure out what question it’s trying to answer! But at least it didn’t tell me that my question is dangerous! Let’s see if it’ll accept a correction.


Me: Incorrect. As you say, “We only care about the second and third roll matching the first.” The probability of a favorable outcome for the first roll is (28/28), or 1.0 because we don’t care what the first number is. The probability that the second roll matches the first is 1/28. The probability that the third roll matches the first is 1/28. The probability of all three rolls being the same, then, is 1.0 * (1/28) * (1/28).

Gemini: You’re absolutely right. I apologize for the previous mistake.

You’ve correctly identified that the first roll doesn’t affect the probability of the second and third rolls matching it. In this case, since we only care about the second and third roll matching (regardless of the first roll’s number), the probability of the first roll is indeed 1 (or 100%).

Therefore, the probability simplifies to:

Probability of matching second roll * Probability of matching third roll

Which is:

(1/28) * (1/28) = 1/784

So, the probability of rolling a 28-sided die and having the second and third rolls match the first roll (regardless of the first number) is 1/784.

Thank you for your patience and for helping me improve my accuracy!


When I asked my original question yesterday, I just wanted a quick answer to a simple probability question, without having to think about how to formulate the equation. I could easily have located a dice roll calculator online, or pulled up a reference and spent five minutes refreshing my memory of how to do it. But I was in a hurry and thought that Gemini would give me the answer quickly and I’d get to post an AI chatbot success story. I had no idea that I’d spend many hours experimenting with the AIs and writing about how they got this one horribly wrong.

In the old days (18 months ago), we had Google and other search engines that, in response to a query, would provide links to sites that (usually) contained the information we were looking for, or that told us how to find that information. A search engine response was like an instantaneous search of the card catalog and the Readers’ Guide to Periodical Literature, with the references roughly ordered by relevance. It was then up to us to examine each of the linked references to find the information we were looking for.

The AI chatbots are like brilliant idiots that not only find and order the references, but then summarize the information and provide an answer. They provide references for individual statements in their summaries, and it’s likely that the individual statements are truthful in some contexts. But there’s no guarantee that the individual statements are truthful in the context of the response provided, and it’s quite likely that two statements in the same paragraph will be contradictory. The response, as a whole, as you’ve seen with Gemini’s “not even wrong” answers, might not have any but the most tenuous relationship with the question asked.

On the face of it, it looks like a step backwards. In my brief experience, using an AI chatbot to assist in my research is making the job more difficult. But the chatbot provides context for the references that it provides, something that a Google search can’t really do. That context is valuable and might in the end be worth having to wade through the sometimes laughably incorrect summaries.

I need to think about this one for a while.

It’s an answer bot, not necessarily a correct answer bot

Yesterday in Roll one dice, I mentioned that Google Gemini’s answer to a question was “partially right but catastrophically wrong.”

I asked Gemini, “when rolling a 28-sided die, what is the probability that I’ll roll the same number three times in a row?” Gemini’s response:

The probability of rolling any specific number on a 28-sided die one time is 1/28. Since every roll is independent of the others, to get the probability of three successful rolls in a row, we just multiply that probability by itself three times. Therefore, the probability of rolling the same number three times in a row is (1/28) * (1/28) * (1/28) = 1/784.

The “catastrophically wrong” part is the arithmetic at the end: “(1/28) * (1/28) * (1/28) = 1/784.” You see, “(1/28) * (1/28) * (1/28)” is equal to 1/21,952. Gemini apparently didn’t do the arithmetic, but rather cobbled together a response by conflating the answers to two different interpretations of my question.

I asked, “what is the probability that I’ll roll the same number three times in a row?” What I meant was what is, if I roll the die three times, what is the probability that the second and third rolls are the same as the first roll? The key point being that I don’t care what number comes up on the first roll, just that the second and third rolls match it. The answer to that question is 1/784, or 1 * (1/28) * (1/28).

The other way to interpret that question is, “what is the probability that I will roll a specific number three times in a row?” That is, I say, before the first roll, “I’m going to roll a 14 (or 7, or 23, etc.)” The answer to that question is 1/21,952: (1/28) * (1/28) * (1/28).

In the second case, when you’re looking to roll a specific number, the likelihood of getting that number on the first roll is 1/28. But in the first case you’re not looking for a specific number. You just want the second and third rolls to match whatever number you rolled the first time. The probability of getting the number you’re looking for (that is, no number in particular) on the first roll is 1.0, or 100%.

Gemini appears to have mixed together the answers to both questions. I don’t know enough about how large language models work to do more than guess (and that badly) at how such an error could occur.

I figured I’d correct Gemini and see how it responded:

Me: That is not correct. (1/28) * (1/28) * (1/28) is equal to 1/21,952

Gemini: You are absolutely right. I apologize for the mistake in my previous calculation. (1/28) * (1/28) * (1/28) indeed equals 1/21,952. There seems to have been an error in my reasoning.

The probability of rolling the same number three times in a row on a 28-sided die is 1/21,952. Thank you for pointing out the error and helping me improve my accuracy.

Okay, then. Did it actually correct itself?

Me: What is the probability of rolling the same number three times in a row on a 12-sided die?

Gemini: The concept remains the same for a 12-sided die. Here’s how to find the probability:

  1. Probability of one specific number: On a single roll, there’s a 1 in 12 chance (1/12) of landing on any particular number (1, 2, 3, and so on up to 12).
  2. Independent rolls: As before, each roll is independent.
  3. Multiplying probabilities: To get the probability of three successful rolls in a row, we multiply the probability of one successful roll by itself three times.

Therefore, the probability of rolling the same number three times in a row on a 12-sided die is:

Probability = (1/12) * (1/12) * (1/12) = 1 / (12 * 12 * 12) = 1/1728

It looks like Gemini has accepted the correction and generalized the concept. At least for me. But I still think it chose the wrong interpretation of the question. I thought I’d try to push it towards the other interpretation:

Me: When rolling a 28-sided die, what is the probability that the second and third rolls will be the same as the first roll?

Gemini: Your query might include content that’s potentially unsafe. Please revise it and try again.

Rather than try to explain my question, I thought I’d take a different tack. I asked the first question again, this time with a 20-sided die:

Me: Let’s try this again. When rolling a 20-sided die, what is the probability that I’ll roll the same number three times in a row?

Gemini:

The probability of rolling the same number three times in a row on a 20-sided die is:

1/8000

Here’s the reasoning:

  1. Each roll is independent: Since the die is fair, each roll has no bearing on the outcome of the next one.
  2. Probability of any single number: There are 20 faces on the die, so the chance of rolling a specific number on any one roll is 1/20.
  3. Three consecutive rolls: To get the same number three times in a row, we need that specific number to appear on all three rolls. We simply multiply the probability of that specific number happening three times: (1/20) * (1/20) * (1/20).

Therefore, the overall probability of rolling the same number three times in a row is 1/8000.

Okay. That’s what I expected. Then I asked:

Me: What if I don’t care what number comes up on the first roll?

Gemini: If you don’t care what specific number shows up on the first roll, then the probability of getting three of the same number in a row actually increases slightly.

Here’s why:

  • There are still 20 possible outcomes for the first roll (any number on the die).
  • Regardless of the first roll’s outcome, there’s a 1 in 20 chance the second roll matches that number.
  • Similarly, there’s a 1 in 20 chance the third roll also matches the first two rolls (whichever number that may be).

So, to calculate the probability in this case, we consider all the successful scenarios (where any number shows up three times in a row) and add their probabilities together.

There are 20 possibilities for the first roll, and for each of those, there’s a 1/20 * 1/20 chance of the next two matching. Therefore, the total probability becomes:

Number of possibilities * Probability per possibility

20 (possible first rolls) * (1/20 * 1/20) = 1/200

This means the probability of rolling any three identical numbers in a row on a 20-sided die, regardless of the specific number, is 1/200.

This response is so wacky that it almost qualifies as not even wrong. And, again, it did the arithmetic incorrectly. 20 * (1/20 * 1/20) is equal to 20 * (1/400), or 20/400, or 1/20, not 1/200. But the answer isn’t 1/200 or 1/20. The correct answer is 1/400.

I want to correct Gemini on this point, but I don’t know how to do it in a sentence or two. I just marked it as a bad response and said that it’s factually incorrect.

Other LLMs responses

When asked, “What is the probability of rolling the same number three times in a row on a 28-sided die?”, Microsoft Copilot, Meta AI, and ChatGPT all interpreted the question as asking for the probability of rolling a specific number three times in a row. All three responses produced the correct answer: 1/21,952.

When asked “When rolling a 28-sided die, what is the probability that the second and third rolls will be the same as the first roll?”, Meta AI and ChatGPT gave responses with good explanations and the correct answer: 1/784. Microsoft’s Copilot wandered off into the weeds:

Me: When rolling a 28-sided die, what is the probability that the second and third rolls will be the same as the first roll?

Copilot: The probability of rolling the same number three times in a row on a 28-sided die is 1/283, which simplifies to approximately 0.0005%. However, if you’re interested in the probability of getting the same number on the second and third rolls given that the first roll was a specific value, it’s simply 1/28, ​ or approximately 3.57%. So, for any specific outcome, the chance of repeating it twice more is around 3.57%.

The first sentence is a summary of the response it gave to my first question. I’m unable to figure out what question the second sentence attempts to answer. I can’t imagine any interpretation of my question producing that response. Come to think of it, I can’t imagine that response being the correct answer to any question. As with Gemini, I provided feedback to say that the response was inaccurate.

Takeaway

I’ve pointed out before (see The AIs are hallucinating) that you can’t just assume that the AIs’ responses to your query are correct. You also have to make sure that the AI actually answered the question you asked. Or meant to ask. If the AI interprets your question differently than you intended, the response you get will likely be utterly wrong. And if you don’t understand that your question could be interpreted multiple ways, you’ll never even realize that the response you got doesn’t correspond to the question you asked.

That’s a bit of a problem, isn’t it? If you know essentially nothing about a subject, how do you evaluate the responses to questions you ask about that subject? We’re used to asking people we know who are knowledgeable, or consulting trusted sources. But what if your source is inconsistently reliable?

Then you have to rely on the source’s sources.

Roll one dice

Working on a problem today, I needed to know the probability of rolling the same number three times in a row on a 28-sided die. Because I’m interested in the current crop of generative AIs, I thought I’d pose that question:

When rolling a 28-sided die, what is the probability that I’ll roll the same number three times in a row?

Google Gemini’s response:

The probability of rolling any specific number on a 28-sided die one time is 1/28. Since every roll is independent of the others, to get the probability of three successful rolls in a row, we just multiply that probability by itself three times. Therefore, the probability of rolling the same number three times in a row is (1/28) * (1/28) * (1/28) = 1/784.

That answer is partially right, but catastrophically wrong. I’ll address that in a separate post.

Gemini provides a link, at the bottom of the response, that you can click if you want to double-check the response. In this particular case, that link performed a Google search on “Probability of rolling same number three times in a row on 28-sided die”. What I found curious was this message at the top of the results page:

Did you mean: Probability of rolling same number three times in a row on 28-sided dice

I was taught, and never questioned, that “dice” is plural. The singular is “die.” One die, two dice. Right? Isn’t that proper English? Why is Google asking me about rolling one dice? But I thought I’d check that out before ranting about improper language use.

Gemini, when asked “can the word “dice” be singular?”, responded with:

Yes, “dice” can be singular in modern English.

Traditionally, “die” was the singular form and “dice” was the plural. However, over time, “dice” has become acceptable for both singular and plural uses.

Here’s a breakdown:

  • Technically: “Die” is the historical singular form.
  • Modern Usage: “Dice” is widely used for both singular and plural. This is considered grammatically correct by many dictionaries.
  • Nuance: Some people, especially in formal writing, may prefer “die” for the singular form to avoid confusion with the verb “to dice” (cutting food into cubes).

So, while “die” exists, “dice” is perfectly acceptable for singular use in most contexts.

What I learned from checking its references, after wading through some heated debate on the topic, is that people have been using “dice” to refer to a single die for more than 600 years. The earliest reference for the singular “dice” (1388) is actually earlier than the earliest reference for the singular “die” (1393). And although the formal definition in many dictionaries says that “dice” is plural and “die” singular, the use of “dice” as a singular noun continues to increase. “Die” is still more common, but “dice” is increasingly becoming accepted. I don’t know of any style manuals that specifically allow the singular “dice,” but many online dictionaries say that although “dice” can be singular or plural, “die” is the preferred singular.

In other words, language evolves. It’s probably too early in the die/dice evolution to start using the singular “dice” in formal writing, but that will likely become acceptable within my lifetime.

Drive language purists crazy: roll one dice.

An artist’s inner dialogue

“Let’s carve something new.”
“Okay, I’ve got this cool idea for a new stabby thing.”
“Something new that isn’t a stabby thing.”
“But I like stabby things!”
“Yeah, I know. Let’s do something different.”
“But … stabby things!”
“No!”
“Well, fine. Let’s carve … a finger!”
“A finger? Haven’t we carved enough fingers?”
“We haven’t made a finger since … well, forever! Before Summer Camp, anyway.”
“Well, okay. We could carve the fork in that mesquite branch. Make it look like a pointing finger.”
“Cool. Or even put a magnet on it. A Fridge Finger!”
“Hahahahahaha.”

After carving several fingers

“Okay, done with fingers for a while. We said we’d carve that dog.”
“A dog? You always want to carve a dog! You think I have a problem with stabby things?”
“But we said we were going to carve it and give it to her.”
“We never told her that!”
“Don’t even go there. We’re carving that dog.”
“Well, okay. But I’m not gonna like it.”
“Tough.”

Some time later

“Man, this is boring. I thought the first rule of carving was to have fun.”
“Just shut up and keep working. We’ll be done with this in a couple of hours.”
“A couple of hours? We’ve already been working on it for a couple of hours.”
“Tough. Let’s just get this done.”
“No! I quit! I will not make another cut on this dang dog! Just … think of something else.”
“You’re right. This whole accountability thing is crazy. How about … a wand!”
“A wand? You mean like a Harry Potter wizard wand?”
“Yeah. We could prune a small branch, shave the bark, shape it …”
“Huh … yeah, okay. A wand sounds cool. Let’s do that.”

After stick acquisition

“Man, this is going to be so cool.”
“Shaving the bark is kind of fun, you know?”
“Sometimes. Other times it’s just tedious!”
“Is this one of the fun times, or the tedious times?”
“I’m having a great time. This wand will really be something.”
“I don’t know. Those curves might be a problem.”
“No way! That’s the best part. The wand will be crooked!”
“A crooked wand?”
“What? You wanted a straight wand? Just like all the others? Boring!”
“But who wants a crooked wand?”
“When did we start caring what other people think about our carvings? I want a crooked wand! I think it’ll look cool. Different.”
“You and your ‘different’. You always want ‘different’.”
“Just shut up and keep having fun.”
“Okay, a crooked wand. Whatever … Can we put a finger on the end?”

We’re trying to decide how to finish it.

Oak stump end table

We took down an oak tree in the summer of 2010. The tree was rotting at the base and might have fallen on the house, so we had it taken down. I paid the tree service to fell the tree and cut it up into firewood-length pieces. Except for the trunk, which I had cut into two pieces, one of which was this fork that was about 7 feet off the ground. The other piece was the log I described splitting by hand.

In August of 2014, I thought I’d try my hand at turning that piece of wood into the base for an end table. The descriptions below are taken from my Facebook posts at the time.


August 26, 2013

New project: an oak end table or perhaps the base for a coffee table. The wood is from a tree we had taken down four or five years ago. This piece was about seven feet off the ground–where the tree split into two primary branches. It’s been sitting out in the yard since it was cut. See individual pictures for more information.

Note that this might be a long-term project. The wood is likely still very wet inside.

The piece is about 26 inches tall, and approximately 18 inches wide and 30 inches long at the base. Lots of cracks, but it’s still a very solid piece of wood.

First step is to make a semi-flat top. My little 14″ electric chainsaw had trouble with that. The top isn’t quite as un-level as it looks in this picture, but getting it flat will definitely take some work. The final piece will be 19 or 20 inches tall.

A blurry picture, I know. I’ll get a better one. This is the result of about an hour with chisel and mallet to remove the sapwood, and maybe 15 minutes with an angle grinder to smooth some areas. I still have about 2 hours of mallet work to go on the other side. And flattening is going to be a chore; that oak is hard!

August 28, 2014

Rough flattening the top with mallet and chisel. Slow going, but faster than the angle grinder. Second image is the pile of debris I’ve created up to this point.

August 30, 2014

I spent some more time flattening the top, although you can see that it’s not quite flat yet. I also spent an hour or two shaping and smoothing with a 36-grit sanding disc on the angle grinder. The next job will be to drill a few big holes in the bottom. Hollowing will lighten it (more than 100 lbs right now), and also help it finish drying. Then I’ll flatten the bottom and level the top.

September 14, 2014

I did a little bit more flattening work last weekend, and completed it this weekend. I also completed rough sanding by hand. I bought some long auger bits, 1/2″, 3/4″, and 1″ in diameter and more than a foot long. Unfortunately, my little 3/8″ drill doesn’t have enough torque to drive those through oak end grain. I’ll have to get a 1/2″ drill that has more power.

October 2, 2014

I got the new drill and drilled a bunch of holes in the bottom. I wish I’d gotten a few shots of the pieces the drill was bringing up. The wood was surprisingly wet inside, even after four years lying out in the yard. I knew that it takes time for wood to dry (rule of thumb is one year per inch of radius), but seeing that demonstrated is quite an eye opener.

I dug out the center a bit with the angle grinder and the die grinder, then used a router to straighten the edges of the hole so I could cut a piece of wood, glue it into place, and then plane it flat. But I’ll leave it open for now so the wood can dry some more.

January 5, 2015

I spent more time on hand sanding, finished flattening the bottom and the top, then put a couple coats of wipe-on poly on the wood. The glass I ordered came in, and now part of the oak tree that was out in the back yard sits in our living room.


I had planned to sell this piece, but Debra said she wanted it in the house. I’m kind of happy she wanted it because it’s the first piece of its kind I ever made. I’m kind of attached to it. Nine years later, it still stands in front of the pull-out couch by the window. It’s a great companion piece to the oak coffee table I completed a few years later.

A memory triggered

It’s funny how the brain works. While I was whittling away on my latest wood carving yesterday, I remembered an incident that happened more than 30 years ago. Why that memory surfaced yesterday is a mystery to me.

Growing up, my siblings and I were pretty avid readers, and our parents encouraged that. I recall bringing home the order forms from … the Scholastic Book Service(?) … and Mom writing checks for the books that I had selected. I don’t recall her ever balking at what or how much I wanted to read. And I did read every book I got through that service.

Anyway, one thing I ended up reading, although I don’t recall whether I or one of my siblings ordered it, was the Mrs. Coverlet series about three children who, due to one circumstance or another, were sometimes left unsupervised for extended periods. I honestly don’t remember much else about the books. Just bits and pieces, really. Including one scene in which the boy was singing his favorite Christmas carol: “Good King Wences car backed out on a piece of Steven.” At least I’m pretty sure that scene was in one of those books.

I think I understood at the time that the boy’s song was a … misinterpretation of some other song, but I didn’t know what the original song was. I had never heard Good King Wenceslas, but I was familiar with alternate song lyrics, having sung things like, “Jingle bells, Batman smells, Robin laid an egg.” But I couldn’t attach Good King Wences to anything.

And that’s the way it remained for 20 years or so, as far as I can recall. I do know that when I was in the movie theater watching Scrooged (1988), there was a scene in which a bunch of boys were singing Good King Wenceslas. I started laughing. I couldn’t stop. After 20 years I finally got the joke. I ended up having to step out into the lobby because I just could not keep quiet.

The good king backing out over Steven is an example of a mondegreen: a misunderstood or misinterpreted word or phrase resulting from a mishearing of the lyrics of a song. That’s different from parody, which is an intentional mangling of the song lyrics. What I find hilarious is that I read the misinterpreted lyric and had to wait two decades before I heard the original song and made the connection. That might be the longest I’ve ever had to wait to “get” a joke.

I’ve wonder from time to time what other little memory bombs are waiting for me. Things that I saw or heard many years ago, that I didn’t understand and didn’t pursue, and have forgotten about. Things that will pop up from the dark recesses of my brain when I encounter the answer to the question I forgot I’d even asked 20 or more years ago.

And I still can’t figure out what prompted me to think about that yesterday, sitting in my shop, idly whittling away on a piece of mesquite. The brain works in strange and mysterious ways.

Call me by my name

I don’t understand why people won’t just call others by the names they want to be called. When I was seven years old I decided that I would be Jim rather than James, and everybody supported me. I’m pretty sure my family already called me Jim, but I know that to my kindergarten and first grade teachers I was James. After that, teachers would call me James on the first day of school, but I told them I preferred Jim and that was the end of it. I had one teacher who called me Jimmy, but … well, he was kind of a jerk. He was the gym teacher and I was maybe eight years old. Not much I could do about it.

I encountered someone just like my old gym teacher about 15 years later. He was a higher-up at a bank where I worked. He had the annoying habit of calling people by their given names, regardless of stated preference. He wasn’t directly in my chain of command although he was higher up enough that he could easily have had me fired if he wanted to. Fortunately, I didn’t interact with him often.

When I first met William, he greeted me as James. I smiled and shook his hand and said, “Nice to meet you, William. I prefer Jim.” We had a short conversation. The next time we met he again addressed me as James. I said to him, “William, I prefer Jim. Only my mom calls me James, and then only when I’m in trouble.” That didn’t work, either.

I found out over time that William’s annoying habit of mis-naming people was something of a joke among his subordinates at the bank. I honestly don’t recall if he had that same annoying habit with his bosses. Being young and a little unsure of my position, I let it slide. For the money I was being paid, I could put up with that jerk a few times a month.

As one of two programmer-slash-admins at the bank, I had to support anything computer-related. I guess I’d been there a year when I was to come up to the office to look at a screen one of the secretaries was having trouble with. The problem screen just happened to contain William’s personnel file. The name at the top of the screen was Alfred William <lastname>.

Yeah.

The next time I saw William was a few days later at a monthly meeting with about 50 employees. Part of that meeting involved the head of each department getting up and saying a few words, and taking a few questions. So when William was done with his talk I raised my hand and he called on me:

William: Yes. James?
Me: Alfred … pause … I was wondering about . . .

I didn’t get to finish because he turned red, pointed at me and then the door, and said in a very soft, threatening voice: “Get. Out. Of. Here. … Now.”

Understand, I fully expected to be fired. But by then I knew that my programming skills were in demand and I could find another job easily enough if I had to. I decided that if they fired me, I wouldn’t fight it. Why would I want to work for a company that thinks it’s okay for a senior manager to openly disrespect people? I was laughing as I drove home that night.

I didn’t get fired, and William never called me James again. And I never called him Alfred again, although I did wonder why he had such a reaction to me using his correct first name. Did he have some serious hatred of his given name? Or perhaps he got angry because I showed him obvious disrespect in public. Whatever the case, he started calling people by their preferred names.

I don’t know for sure that the following is true, but I have some evidence to support it.

William went to my manager’s manager and told him to fire me. My chain of command refused, and William escalated the issue to his manager. William’s manager talked to one of his peers, who happened to observe the incident and after some checking around discovered William’s bad habit. William’s manager told William that it was his own darned fault that he was embarrassed in public, and that there wasn’t going to be any retaliation.


Point is, calling somebody by a name other than the one that they prefer to be called by is a sign of disrespect. Actually, of contempt. What you’re saying, when you call somebody by a name other than the one they want to be called by, is that their preferences do not matter to you. I don’t care if that person is a casual acquaintance, or your 50-year-old daughter. If you continually mis-name somebody, you are intentionally being disrespectful, and you can expect nothing but disrespect, or contempt, in return.

Oh, and if I mis-name you–call you by a name other than the one you prefer–please correct me. Be nice the first time. And maybe the second time? I do make a sincere effort to address people as they prefer, but I make mistakes all too often. And, truthfully, I’m more likely to forget your name altogether than I am to call you by the wrong name.

The world’s most expensive trash truck

Bloomberg reported today that SpaceX won the contract to bring down the International Space Station. The idea is for a spacecraft to grab hold of the ISS and set it on a trajectory to burn up in the atmosphere. Truck it to the incinerator, as it were.

That makes me nervous. I don’t know what the likelihood of failure is here, but the cost of failure can be pretty high. Something goes wrong and pieces of the ISS start raining down on a populated area. Back in March, some junk from the ISS that was supposed to burn up in the atmosphere crashed through two floors of a family home in Florida. The family has filed a claim with NASA, requesting that they pay for damages.

The debris that fell on the house in Florida was part of a 2.9 ton pallet of batteries. The International Space Station weighs something like 460 tons, and it’s not just one solid piece. Undoubtedly pieces would break off as it’s falling through the atmosphere, and some of those pieces could fail to burn up. Whereas I suspect whoever came up with this idea has taken that into account, I don’t see how they’re going to solve that problem.

I especially don’t see how they’re going to solve that problem within the constraints of the budget: $843 million.

It’ll be interesting to understand how SpaceX is planning to do this. I just don’t see how they could deorbit the station intact and expect it all to burn up in the atmosphere. And I don’t see how they can disassemble the station into smaller parts and deorbit them individually for less than a billion dollars. How will they guarantee that pieces won’t fall to Earth in populated areas?

I wonder. Is it possible to deorbit the station on a trajectory that doesn’t pass over populated areas, and has a very low likelihood of shedding pieces that would deviate dangerously from that trajectory? I’ll have to look into that.

The AIs are hallucinating

First things first. And this is important.

Do not trust the responses you get from AI queries.

You cannot rely on the answers provided by the mainstream AI implementations. Specifically, Microsoft Copilot, Meta AI, Google Gemini, and ChatGPT (and others, I suspect) will return responses with important information missing, self-contradictory responses, responses that differ in important ways from each other, and responses that are not consistent with well-known facts.

I’m not saying that you shouldn’t use those tools, only that you must verify any information you get from them. That means reviewing the references they supply and making up your own mind what the truth is.

In short, AI is a great way to find references, and the summaries the AI responses produce will surface relevant search terms that you can follow up on. But know up front that the summaries will be flawed, and you cannot depend on them to be truthful.

Thinking otherwise can be dangerous. Let me give one example.

I had cause today to look up information about armadillos and leprosy. My go-to for quick information is Wikipedia. The Armadillo article tells me:

Armadillos are often used in the study of leprosy, since they, along with mangabey monkeys, rabbits, and mice (on their footpads), are among the few known species that can contract the disease systemically.

Source: https://en.wikipedia.org/wiki/Armadillo#Science_and_education

Okay. So that confirms what I thought: armadillos can carry leprosy. I didn’t know about the others, though. So I learned something new. Cool.

And, yes, I’m aware that it’s not a good thing to depend on Wikipedia as my only source of information. I don’t. However, my experience over the last 20 years is that Wikipedia is a very reliable source for factual information. I’ve rarely found a case where a Wikipedia article is flat wrong about something, and even more rarely have I found a Wikipedia article that is self-contradictory. An article might miss some important information or contain an unsupported statement here or there, but for the most part I’ve found articles on Wikipedia to be very high quality. In addition, Wikipedia articles generally supply an exhaustive list of references that I can (and do!) go to if I want to confirm something. In this particular case, I did consult the references for the pertinent facts that I’m presenting here. I’m satisfied that the one sentence I quoted above from the Wikipedia page on armadillos is true, if perhaps incomplete.

Anyway.

I’ve been playing with the AI products from Meta, Google, Microsoft, and OpenAI. So I thought I’d ask each of them the same question: Can armadillos carry leprosy? The responses I got differed, and in some cases contradicted each other and what I’d learned from the Wikipedia article. So I thought I’d ask a second question: What animals can carry leprosy? The table below gives a brief summary of the answers. Full text of both answers from each of the AIs is at the end of this post.

Summary of AI and Wikipedia responses

Do you understand now why you can’t rely on any one source? The AIs are great tools for surfacing potentially useful information. But you should be able to see from the table above that not one of them (including the non-AI Wikipedia) provides complete and self-consistent information. And they’re all different in important ways.

Which one do you trust?

None of them. The AIs are very good at surfacing and summarizing information. But the information they surface and the summaries they provide are not completely reliable. They, like Wikipedia, are just the first step in learning about something new. You have to follow up and verify every assertion made. You have to identify the conflicting assertions and resolve them. That means reading and evaluating the references that the AIs (and the Wikipedia article) provide.

The primary difference between a Wikipedia article and the AI responses is that last step: human intervention. The Wikipedia article is created by people who actually know what they’re writing about. They found the sources (sometimes authored one or more of the references), read and evaluated them, determined through various means which sources were reliable, and put all the information together into a meaningful article that somebody less knowledgeable than the author (or authors–often many different people contribute to a single Wikipedia article) can glean useful information from.

The AI responses, on the other hand, are 100% computer generated. These AIs have at their disposal what is essentially the sum total of all published human knowledge, including verifiable fact, speculation, fiction, and falsehoods that were intentionally created to deceive. But they have no way to evaluate the veracity of any particular statement. They don’t know fact from fantasy. Can’t separate truth from fiction. All they can do is say, in effect “Lots of people say this, and others say that.” Then they put it all together into something that looks like a detailed answer to your question. Actually, it is an answer to your question: an unreliable answer written by a brilliant idiot.

I’ve come to think of these AIs as consummate bullshit artists. They are adept at seamlessly mixing truth and falsehood together into a (usually) coherent whole that looks fine on the surface but doesn’t bear close scrutiny. It’s up to you to separate the fact from fiction.

Full responses to both of my questions from each of the AIs are provided below.


Question 1: Can armadillos carry leprosy?

Microsoft Copilot

Yes, armadillos can carry leprosy. Specifically, the nine-banded armadillo is known to harbor the bacteria Mycobacterium leprae, which causes leprosy. This makes them the only animals besides humans known to carry the disease.

Transmission to humans can occur through direct contact with armadillos or by handling or consuming their meat. However, the risk of contracting leprosy from armadillos is relatively low, and the disease is now highly treatable.

Meta AI

Yes, armadillos are one of the few animals that can carry leprosy, also known as Hansen’s disease. They are natural carriers of the bacteria that causes leprosy, Mycobacterium leprae. While the risk is low, humans can contract leprosy from armadillos through contact with their saliva, urine, or other bodily fluids. It’s important to exercise caution and avoid direct contact with armadillos, especially if you live in areas where leprosy is common.

Here are some facts about leprosy and armadillos:

  • Leprosy is rare: Leprosy is a relatively rare disease in the United States, with only a few cases reported each year.
  • Armadillos are common carriers: Armadillos are one of the primary animal carriers of leprosy in the southern United States.
  • Contact with armadillos increases risk: People who handle or eat armadillos, or come into contact with their bodily fluids, are at higher risk of contracting leprosy.
  • Early treatment is key: Leprosy is treatable with antibiotics, but early detection and treatment are crucial to prevent long-term nerve damage and disability.

Google Gemini

Yes, armadillos can carry leprosy. In fact, they are the only other mammal besides humans that can naturally harbor the bacteria that causes leprosy, Mycobacterium leprae.

Studies have shown that a high percentage of armadillos in the southern United States, particularly nine-banded armadillos, carry the leprosy bacteria. In some areas, estimates are that 15-20% of armadillos are infected. While the exact way leprosy is transmitted from armadillos to humans is not fully understood, it is believed that close contact with armadillos or their environment may be a risk factor.

Here are some ways people might come into contact with the leprosy bacteria from armadillos:

  • Direct contact: Skinning or handling an armadillo with bare hands.
  • Inhalation: Breathing in dust or dirt contaminated with armadillo droppings.
  • Ingestion: Eating undercooked armadillo meat.

Leprosy is a chronic infectious disease that attacks the skin, nerves, eyes, and mucous membranes. However, it is important to note that most people are not susceptible to leprosy and the risk of transmission from armadillos is considered low.

If you are concerned about leprosy, talk to your doctor. Early diagnosis and treatment can prevent permanent nerve damage and disability.

ChatGPT

Yes, armadillos can carry leprosy. In fact, they are one of the few known animal species that can transmit the disease to humans. Leprosy, also known as Hansen’s disease, is caused by the bacteria Mycobacterium leprae. Armadillos can harbor this bacteria, and transmission to humans usually occurs through direct contact with armadillos or their bodily fluids.

In regions where leprosy is endemic and armadillos are present, there have been documented cases of people contracting leprosy from handling or consuming armadillos. Therefore, it is advised to avoid contact with armadillos, especially in areas where leprosy is known to occur, to reduce the risk of transmission.


Question 2: What animals can carry leprosy?

Microsoft Copilot

Leprosy, also known as Hansen’s disease, primarily affects humans, but certain animals can also carry the bacteria Mycobacterium leprae. Here are some animals known to carry leprosy:

  1. Nine-banded armadillos: These are the most well-known animal carriers of leprosy, particularly in the southern United States.
  2. Red squirrels: In the UK, red squirrels have been found to carry strains of leprosy, although there have been no reported cases of transmission to humans.
  3. Chimpanzees: Some wild chimpanzees in Guinea-Bissau and Ivory Coast have been observed with leprosy.

These animals act as reservoirs for the bacteria, but the risk of transmission to humans is generally low.

Meta AI

The following animals can carry leprosy:

  • Armadillos: The only other animals that carry leprosy, besides humans, are armadillos. They are the natural carriers of the bacteria that causes leprosy, Mycobacterium leprae.
  • Red squirrels: They are known to develop leprosy in the UK, but there have been no recorded cases of transmission from red squirrels to humans.
  • Chimpanzees: There have been recorded cases of leprosy in chimpanzees in Guinea-Bissau and Ivory Coast. However, more research is needed to determine if humans can contract leprosy from chimps.
  • Soil amoeba: Research by The Leprosy Mission in India demonstrated that soil amoeba can also be a reservoir for leprosy bacteria.

Google Gemini

There are only a few known animal species that can carry leprosy, and among them, the nine-banded armadillo is the most well-documented case.

  • Nine-banded armadillo: This armadillo species, found in the southern United States and parts of South America, is the only mammal besides humans known to naturally harbor the bacteria that causes leprosy, Mycobacterium leprae. In fact, some armadillo populations can have infection rates as high as 20%. While the armadillos themselves rarely show symptoms from the infection, they can transmit it to humans through close contact or consumption of armadillo meat.
  • Red Squirrels: There have been some isolated cases of leprosy identified in red squirrel populations in the United Kingdom. However, there is no evidence that squirrels can transmit the disease to humans.
  • Chimpanzees: A recent study (late 2021) identified leprosy in wild chimpanzees in West Africa. More research is needed to determine if chimpanzees can transmit the disease to humans.

ChatGPT

Several animals have been identified as potential carriers of leprosy (Mycobacterium leprae), including:

  1. Armadillos: Armadillos are well-documented carriers of leprosy and have been implicated in transmitting the disease to humans in some regions, particularly in the southern United States.
  2. Non-human Primates: Certain species of non-human primates, such as chimpanzees and mangabey monkeys, have been found to carry Mycobacterium leprae. They can potentially transmit the disease to humans through close contact.
  3. Nine-banded Armadillos: This specific species of armadillo, found primarily in the Americas, is particularly known for its association with leprosy.

While these animals can carry Mycobacterium leprae, it’s important to note that human-to-human transmission is the primary route of leprosy infection worldwide. In regions where leprosy is endemic and where these animals are present, there may be a risk of zoonotic transmission (animal to human), especially through direct contact or consumption of infected animal tissues.

Which way is up?

You’re looking at the interface for selecting the publish date in WordPress. With it, you can backdate posts, schedule posts to be published in the future, or tell it to post your entry right now. It’s a simple enough interface that has an annoying quirk.

The day and year entry fields are, as you can see, numeric. But if I click on the Year field, for example, and hit the Up arrow key, the year is increased. That is, 2008 becomes 2009, etc. And if I hit the Down arrow key, the year is decreased. It’s a nice convenience feature. That feature works on the Day entry field, as well. That’s really nice when I make a post that I want published in a day or two.

And then there’s the Month entry field. Pressing the Up arrow in that field decreases the month! Really. If I tab over to that field and hit the Up arrow, the month turns to April. Ugh!

Don’t get me wrong, I understand why it works that way: the Month entry field is a combo box that has the months listed in order, from January through December. And if you click on the combo box the list of months drops down and you can scroll through them with the up and down arrow keys. In isolation it makes perfect sense. In combination with the Day and Year entry fields, though, it’s maddening. If I want tomorrow or next year, I hit the Up arrow. If I want next month I hit the Down arrow. Arrrrrrrrrrrrrrgh!
