Thread Name: BS: Stupid riddle but can you explain it?
Subject: RE: BS: Stupid riddle but can you explain it?
frogprince, if one declares those stupid who don't find the solution it is critically important at least to be sufficiently precise and correct in the formulation of the test. Read what I wrote at 09:45 AM.

The "Twins at a Fork in a Road" riddle is well-known (in the style of ancient Greek "Liar paradoxa", but probably much newer) and not all that easy to solve. Here too, a complete formulation is required, e.g.

At a fork in a road, a traveller does not know which way to take. He meets a man, about whom he happens to know that he is one two identical twins who both know the correct way, but will answer only one question per traveller with either "yes" or "no". One brother will always give the correct answer, the other one the opposite, and this fact is known to everybody (including the brothers themselves). What question can the traveller ask to find out the correct path safely, although he does not know whether he is talking to the honest brother or the liar? --

The good thing about Mudcat is that everybody can choose whether to just read a thread, post to it, or neither. This one I find interesting for various reasons, otherwise I would have stayed out of it, as I do with most. Thanks, Mr Red; if there is any discomfort it is certainly not your fault.

The art of nitpicking, squabbling, and BSing is not to take it too seriously, but to find new aspects that are interesting or funny.
