There is something seriously erroneous in either this puzzle OR its answer.
1- In this puzzle:
In fact, if the Master really wanted to determine who the wisest one was using this experience, he had ONLY 2 choices to make:
A- All THREE should have RED dots
B- All THREE should have BLUE ones
He doesn't have any other choice!! Why?
Well simple: if he puts 2 RED and 1 BLUE or any other compbination, at least one of the "wise" men will be in a different situation than the others: it will either be easier or harder for him to know the answer, but NEVER THE SAME!
The initial conditions have to be the same for all of them so that the Master can compare their intelligence objectively and scientifically.
2- In the answer and its analysis:
The wisest man is simply the one who thought about the above analysis in 1, and predicted the master's choices. He will them shout out the same color that he sees on the others foreheads!
P.S: He doesn't even have to wait one second to do this!
