These norms provide stability in the long run, preventing the society from decaying into chaos, and ensuring that even monumental change happens slowly. But they also 5 strongly influence individuals to conform to society. For instance, one study in the 1950s showed this very clearly. New students at a university were randomly assigned to live among either conservative students or liberal students. The researchers observed that these new students gradually adapted their values and beliefs over time to fit the 10 norms of their surroundings. 2 Other studies have shown that people followed group norms even when they had direct evidence that contradicted the norm. For example, in one study, people were asked to estimate the length of a line drawn on a piece of paper. People's estimates followed a group norm Soini insmye daug goland that the group 15 even in cases when people could see with their own eyes was wrong. 301 10 aniq 3 Social norms often stifle creativity in groups.

They don't even have difficulty running with the *herd within a few hours. Since young animals are certainly in danger, sometimes for weeks or even months after birth, compared with the human infant, they quickly develop the capacity to protect themselves.
