Tips for solving logic problems quickly?

Hmm . . . not sure

 

Don't play them? Are games really logical????

 

There doesn't seem to be an answer to this. There is no way the blind man could be sure.

The only way to know is if you know the other two are wearing red hats.

If both the sighted people are wearing red they would each see one red and one white leaving them unable to tell their own colour.

If the blind man was the only one wearing red both sighted people would again see one red and one white.

This means there are two ways the sighted people could not know their colours. One where the blind man i wearing red and one where he is wearing white.

Tis a trick i tells ya

 

No but please post more of these. That was fun

Maybe we can come up with a system between us

 

If I'm not mistaking, and this could be since I haven't had a good night sleep in a while, the blind man is wearing a white hat.

As for the question of the thread, I'd say that there are many different logic problems. I think that there is some sort of generalisation but it sure doesn't cover all possible problems. If you are dealing with the problem similar as one you've presented here, I'd say that the quickest way is to see what was the underline idea behind the problem. While reading this one should make a mental note of sorts "three white hats and only two red, there must be a good reason why they gave that". In my opinion the solutions is always in the question itself.

 

Also for the presented problem you could go with truth tables, since you don't have to many combinations, but I didn't go that way. My idea was, if the first one wasn't sure what he had on his head, and the second one also, than that means that they were both seeing one white and one red hat, from which one could draw the conclusion that the hats on their heads were red, and that the hat on the blind man head was white. I don't see a flaw in my reasoning yet, but there is still time.

 

Don't take this in a dismissive way but when stuff like this is posted - my knee jerk reaction is "Ugh, who cares".

I've often wondered if this is common in other INFJs or if this is me just being lazy.

Although, I agree with PJ. The two prisoners with eyesight were wearing ready hats.

 

I find that a lot of NF's struggle with logic. To me, it just doesn't hold much value. My brain is programmed in a much more subjective and philosophical way. Logic really conflicts with that.

 

Sorry but no. I think you are assuming that both red hats have to be worn by someone. It doesn't state that

 

Yea but practice makes perfect, if you are familiar with the Ainstaine's intelligence test, the one with five houses, five men, five types of cigaretes, five pets and five beers, where in the end you are asked who owns a fish as a pet, if you practice that kind of problems on paper first after several of those you'll be ahead of the logic behind them so much that you can solve them in your head without thinking too much about them or even writing anything on paper.

 

Use your Ni, PJ. Trust your feeling!

 

I've working on this and still can't find a solution to your question.
