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.

Conformity does not require threats or rewards. Sometimes seeing others act a certain way is enough to change what you do. In this quiz experiment, fifteen plants know the true purpose and all pick the same wrong answer on purpose, while ten subjects have no knowledge of the design. As you go over each question, you watch whether each subject agrees with the group's wrong answer or stands alone with the right one. That tension — knowing the correct answer but choosing to match the people around you — reveals how powerful simple group agreement can be.
