It's literally called "asch conformity" and it's a well documented phenomenon J man calls it "the hive mind sheeple" effect because he's uneducated but he's not entirely wrong.

The test was basically 6 people being paid actors answering the questions right. The questions were "which of the three lines is the same size as this line" you cannot fuck it up. Eventually, the paid actors start lying after answering right. Most of the time, the actual test subject would answer alongside the paid liars, because he's pressured.
Key words, Asch Conformity, peer pressure and fear of not being in the group.
