A Bias in the Prediction of Tastes
研究发现人们存在“禀赋效应”，即得到物品后会更依恋它。两个实验表明，没有物品的人会低估自己得到物品后的价值判断。
Recent research has documented an `endowment effect' whereby people become more attached to objects they receive than would be predicted from their prior desire to possess the object. In two experiments, we test whether people are aware of the effect--whether they realise that they will become attached to an object once they receive it. In both experiments, subjects without an object underestimated how much they would value the object when they received it.
