research stats strategy

In an experiment that provided participants with an opportunity to buy a discounted coffee mug, those who were told they had been randomly selected to get the discount were 3 times more likely to want to buy than people who believed everyone got the discount. The esearchers say such "special" opportunities may be appealing because people's self-esteem is tied to factors that distinguish them from the crowd.
