Our censorship has sort of gotten a little too far. Too much censorship is just as bad as having none at all. Children need to be exposed to things, because if they don't see it, eventually, it's not like it's not going to happen, but it's just that there needs to be a balance.

The idea of critical windows extends beyond just vision, of course: almost every system in the brain has a critical window when it needs to experience certain stimuli, or it won't get wired up properly. The most obvious example is language: if you don't learn a language early on, it's nigh impossible to become truly fluent.
