مثال 1
A widely cited study found that shoppers offered 24 varieties of jam were less likely to buy any than shoppers offered only 6, a result often summarized as "more choice is demotivating." Later researchers who combined the results of dozens of similar experiments, however, found that the average effect of larger assortments on people's decisions was close to zero. The effect appeared reliably only under particular conditions, such as when the options were hard to compare or when people lacked clear preferences beforehand.
