Langer (1975) Assigned Participants a Lottery Number, or Invited Participants

Langer (1975) assigned participants a lottery number, or invited participants to choose a number themselves. Participants were then asked if they would sell their tickets back, and for what price. The results showed that:

A) those who chose their own numbers gave their ticket back at no cost.
B) those who had been assigned random numbers refused to sell their ticket back.
C) those who chose their own numbers demanded four times more money to resell as those who had been assigned random numbers.
D) those who chose their own numbers were significantly more likely to win the lottery than those who did not.
