Its simply not true that children won't believe they can do something if they don't see someone who looks like them doing it.<p>If it were the case, there'd be all sorts of adopted kids completely incapable of doing things.<p>It is true that if people do not see a certain behavior or do not see that it is successful, they are less likely to adopt the behavior themselves. But even then, children create and experiment with behaviors all the time. Unless, of course, they are actively discouraged from doing so.<p>We don't simply repeat what we see. We are capable of assessing the way people act around us and judging whether or not behavior works.<p>But if children are surrounded by people not practicing successful behaviors and also are actively discouraged from experimenting, its a lot less likely they will be successful at whatever they choose to do.
