There isn't any higher standard knowledge that gets passed around. People learn the fundamentals as children: how to eat solid food, how to clean up after using the washroom, how to talk, etc.

Even those are things that we learn through experiences. If you think you're lacking something, then a therapist can help you work on that skill. There is very rarely ever a clear-cut answer to anything. We all learn through trial and error - some people just have better support systems to help them through it.
