Just as frequently, however, there was no tragedy that preceded people’s transformations. Rather, they changed because they were embedded in social groups that made change easier.

Self-discipline has a bigger effect on academic performance than does intellectual talent.”

Telling someone to run their tongue across their teeth, it turned out, was likely to cause them to run their tongue across their teeth. And when they did, they were likely to feel a film.

Bureaucrats and politicians, rather than making decisions, were responding to cues with automatic routines in order to get re

But we do know that for habits to permanently change, people must believe that change is feasible. The same process that makes AA so effective—the power of a group to teach individuals how to believe—happens whenever people come together to help one another change. Belief is easier when it occurs within a community.

those patterns always remain inside our heads. By the same rule, though, if we learn to create new neurological routines that overpower those behaviors—if we take control of the habit loop—we can force those bad tendencies into the background, just as Lisa Allen did after her Cairo trip. And once someone creates a new pattern, studies have demonstr
