Hi, today I would like to share with you all great presentation by Dan Ariely. You may be surprised how wrong our perception is. In psychology, there is a subject I do not know the correct name of. But, when you decide what book to buy, you cannot decide correctly because you do not know what is inside, so you answer different questions in your mind. Is the book’s face nice? Is the first chapter nice? Etc. So you replace the question that you cannot find the answer you replace it with expectations. But is it impossible to get an answer to the question of how much money CEOs earn around the world? So you answer a lot :). I do not know how this replacement of question should have a name, but I know there is such a thing. So, it is important to find an answer to the right questions, in my opinion. Enjoy this great TED presentation.
