Rational or emotional decisions
To determine whether humans are rational or emotional, it not good idea to ask them: everybody thinks he is a sensibly person. It simply has to be tested, and this has been done, through the following experiment:
A room is filled with a few dozen people, who are shown a picture projected on a screen, containing two diagrams, see below:
The audience is posed the question "Which of the bars in the left-hand diagram is equally large as the one in the right-hand diagram?" It is apparent that the answer is the middle one. Next the audience is instructed to give the next time a wrong answer: the left one. Into the room is introduced our test person, who doesn't know about the instruction. The question is posed again: "Which of the bars in the left-hand diagram is equally large as the one in the right-hand diagram?", and the audience answers openly: the left one. Now what will the test person do: vote for the right one, or go with the crowd and choose the wrong one, or: does he follow his rational mind or his emotions? After having done a number of these tests, the conclusion was that about eighty percent of people vote with the crowd.
So thereby it has been proven: Given a situation where people have to choose between rationality and emotions, people in general choose for their emotions.
