Whether boys and girls respond differently to peer pressure is a social behavior question as much as a scientific one. You set up a group of 10 people secretly told to choose an obviously incorrect response — then one real participant joins without knowing the plan. The group is shown simple shapes and asked to match two that are the same size. The planted members all pick the wrong pair first, putting pressure on the participant who answers next. Running this with 20 male and 20 female participants, then comparing how often each group follows the crowd, reveals whether peer influence shapes choices differently by gender.

A shape-matching task can reveal just how strong the push to follow the crowd really is. Ten planted members all pick the wrong pair on purpose — then one real participant, unaware of the setup, answers the same question. A second question reverses the order so the participant answers before anyone else, giving a baseline free from group influence. Running this with 20 male and 20 female participants makes it possible to compare how often each gender goes along with a room full of wrong answers.

When the group speaks first, conformity grows stronger. In this experiment, ten planted members all pick the wrong pair first — matching two obviously incorrect shapes — before the real participant answers. That order matters. You then reverse it on a second question so the participant answers before anyone else, letting you measure how much the prior group pressure shaped their response. Running this with 20 male and 20 female participants shows whether gender affects how often someone follows the crowd.
