There’s a funny effect called illusory superiority, which refers to how we all think we’re better than other people (especially Americans). For example, in one study, 93 percent of respondents rated themselves in the top 50 percent of driver skills—an obviously impossible number. We believe we have a better memory, and that we’re kinder and more popular and more unbiased than others. It feels good to believe it! Yet psychology has shown us that we are flawed.
