Peterson says that standing up straight with one’s shoulders back can go a long way toward helping someone-even “a loser”-change the way they feel and are regarded in society.

This dynamic can also be observed in human society. Meanwhile, “loser” lobsters, whose serotonin is low, skulk around and startle easily. Dominant lobsters, who win fights over territory, have different brain chemistry than submissive lobsters: their high serotonin levels prompt them to strut aggressively. Rule 1 is “Stand up straight with your shoulders back.” In this chapter, Peterson considers lobsters’ behavior as a model for human behavior. He offers his 12 rules as the best guide he has to walking that border, hoping that as individuals learn to live well, humanity will collectively flourish, too.
