In the first study , 135 Japanese mellow school students solved mazes in exchange for points that could be deal for prize . Before the labor , they had to select whether they would rather get points according to the number of mazes they solved , or be entered into a tournament against other participants , in which you had to puzzle out more labyrinth than the rest of the chemical group to get point ( a competitive environs ) . Only 38 percentage of men who had an older baby entered the tournament , showing a lower druthers for contest than men with no sometime sisters .
In a follow - up survey , 232 university bookman solved math problems for immediate payment , with the same tournament setup . Only 24 per centum of men who had older babe accede the tourney , compare to 48 percentage of the rest of the men .
