追加: 2026-05-23

[00:00:00]Have you ever agreed with a group even when you thought they were wrong? That is exactly [music] what psychologist Solomon Asch wanted to study.

[00:00:08]In the 1950s, [music] Asch created a simple experiment about conformity. One real participant was placed in a room with several other people, >> [music] >> but there was a catch. The others were not real participants. They were part [music] of the experiment. The task seemed easy. The group had to look at a line >> [music] >> and then choose which of three other lines matched it. The correct answer was obvious. At first everyone answered correctly.

[00:00:34]>> [music] >> But then the actors all began giving the same wrong answer. The real participant [music] now had a choice. Should he trust his own eyes? Or should he follow the group?

[00:00:45]Surprisingly, [music] many participants chose the wrong answer, too.

[00:00:48]Not because they could not see the truth, [music] but because the pressure from the group was strong.

[00:00:54]This is called conformity. It means changing your opinion or behavior [music] to fit in with others.

[00:01:00]Asch's experiment shows that people often want to belong even when the group is clearly wrong. This is still relevant [music] today. In school, friend groups, and on social media, people may change how they act, dress, or speak just to fit in.

[00:01:15]The Asch experiment reminds [music] us of something important. Sometimes it takes courage to stand by what you really think.
