American Princeton university psychology professor Daniel card Ni the Man discover after thorough research, people while doing decision, usually be not strictly estimate correct income, but the good and bad that a little bit easily and quickly evaluates it.Professor Ka Ni Man once raised such an example and supposed the United States be saving to cure a kind of disease, saved to cure object to totally have 600 people, for this person put forward two kinds of two kinds of method descriptions that was different to save to cure a project, pass an underneath respectively:Describe a:There are two kinds of projects now, project A, can save to live 200 people whom 600 people win;The project B there is the possibility of 1/3 saving to live all 600 people, the possibility of 2/3 is a to also save not to live.Experiment result BE:People would not like to take risk, more would like to alternative A.Describe two:There are two kinds of projects now,oakley polarized sunglasses project C, will make 400 people death;The project D there is possibility no man death of 1/3 and have the possibility of 2/3 600 people's all death.Experiment result BE:The death is 1 kind to lose, people would like to even go to risky choose to have the affair to all lead, consequently alternative D.In fact, AN and C, the B is similar to the D essence, different description method, but the result is a vast difference between the two, people what to adopt is an as different as chalk and cheese mindset while facing income and loss.The economist thinks that under majority of circumstances that can compute, people's value to the thing lost presumably wants far far Gao Chu to get the value estimate of same thing.For giving award to the work of the Man of card Ni, the Royal Swedish Academy of Science decides 2002 Nobel economics the prize give him, the reason is that he blended with economics psychology research achievement together and especially at relevant the indetermination status make how people do the research of judgment and decision.Because the psychologist gets involved,oakley sunglasses wholesale our understanding to the mankind reasonableness seems to be clearer, card Ni Man's colleague's Richard in the university of Chicago is virtuous to fill Lei to once do such an experiment, let people describe in the following 2 kinds in carry on a choice:Describe a:Suppose you got a kind of disease, having the possibility of 1/10000 would die abruptly and have now a kind of medicine ate hereafter can death of the possibility lower to 0, you would like to spend how much buy this kind of medicine?Describe two:Suppose you are healthy, suddenly have the new medicine that the medicine companies want to seek some people test them, but this kind of medicine will have the possibility of 1/10000 to suddenly die, so you will request the medicine company how much come to compensate?In the participant of this experiment, the many people says to the description a short while to buy a medicine with several hundred dollars, since low thousand times of an of the death all lead, but on the other hand, for describe two, even if is the repair that can acquire several decuples, they don't wish to take part in this experiment that a death increased thousand times all leads as well.In fact, in the people economic behavior situation like this is also all like that, more see in the life.You really want to buy the ticket listens to a concert, but before going out, you discover that you threw an a piece the phone card of 200 dollars, but the concert admission ticket is just a 200 dollar per piece, whether you also buy ticket to go to the concert?The survey suggests that most of answerers still choose to listen to.But if the circumstance becomes for a while, before going out, you threw the concert admission ticket that your 200 dollars money buy, and whether you also go and buy an admission ticket again?Result but BE, greatly parts of persons all say not to go.Can cautiously consider, these two answers aboves are in fact self-contradictory.No matter if what to throw is a phone card or a concert admission ticket, in fine is the thing that threw to lose to be worth of 200 dollars,supreme snapback hats want to go to the concert, all want again spend 200 dollars to buy a ticket.Of so appear two kinds of different choices, its reason is a key dessert reason account.In fact, in the people's brain, phone card and concert admission ticket are returned in the different account, then fill the mental account that the Lei calls.It is the budget and expenditure of account that can't influence concert place to throw to lose a phone card, greatly parts of persons still keep choosing to go to the concert.But concert admission ticket and the admission tickets needing to be bought again afterwards throwing was all returned to go into the same account, so have a liking for go to seem and spend 400 dollars to listen to a concert.People certainly feel not so worthwhile.
