Moderation note: Moved the first post of this thread from the math forum thread 5341, because it’s about human psychology, not math. Does anybody knows why people always pick number 3??? You if write down on a piece a paper the numbers 1, 2, 3 e 4 in sequence but not together, then you show to a friend and ask him to pick one of them and tell you what number they picked right away. Well, most people will pick number 3. It's very impressive. B) To make it a trick, you write the number 3 on the other side of the paper before to approach a person. Then you write the four numbers and ask him to pick one. Out of 10 people, 9 you pick number 3 unless they have the numbers 1, 2 or 3 as favorite numbers for some personal reason. Once they say "three" you ask them to flip out the paper. They will have the felling that you have read their mind. People always Freak:eek:UT!! But i have know Idea whey it works. Do you know? :hihi:
