For this joke to logically work, logicians must be weird people who always know whether they want a beer or not. Because if it happened that the first guy just hadn't made his mind up yet, then the third guy's conclusion could be wrong.

They all had made up their mind. You don't need to know the others decision to answer No to the question, but you do to say yes. If the first didn't want a beer they could definitively answer no. They did, but didn't know the others decisions so couldn't say yes. Same with the 2nd. The third could say yes because he knew the other two didn't say no, so whatever they wanted was the answer

OCs point was that if the first person hadn't made up their mind yet, that would also cause them to say "i don't know", but the two following logicians seem to assume that the first person said "i don't know" because they wanted it but didn't know if the other two did

It's a false dichotomy and faulty logic if you look too closely

But it's a pretty funny joke

If he has not made a mind, he does not want beer. He might want beer few moments later, but at the moment of answering the question, he does not. That's what my logic tells me.

Hmm, that's true, if the question is if all three in this moment wants a beer, then not knowing if you want it means that you don't currently want it in the strictest sense 🤔

This is a good point, but I'll move the goalposts very slightly and suggest that human brains are capable of wanting something without knowing that they want something. For example, if you say you don't know whether you want a beer, and then the person next to you orders a beer, then at that moment, you might realize that you really did want a beer before.

It's been shown that your brain makes it's decision several seconds before your consciousness is aware of it.

So, it just takes a second for the Ego to catch up with the Id

More like 100-300 ms, but yes. However, this is much shorter time than to say “I do not know”

What does it even mean to make a decision if you're not aware of it?

[–] [email protected] 2 points 1 year ago

I think the areas of your brain that would be responsible for carrying out the decision start activating before you're consciously aware of making the decision.

It's been a hot minute since I read the article on it, so I'm not 100% sure on the explanation.
