If you had asked me when I was younger to to make a list of valuable skills, I probably wouldn't have included the ability to notice anomalies, but I'm increasingly convinced this is one of the most valuable skills of all.
If I ask what the difference is between this and the skills I would have listed, it's that the latter were taught (or at least measured) in school. But how could you teach noticing anomalies in a way that could be turned into a grade?
As soon as I asked that question, I realized you probably could teach noticing anomalies, if you taught essay writing properly instead of teaching it as a bad imitation of research on English literature (http://paulgraham.com/essay.html ).
Can you give us an example of how this ability translates to utility in the real world?
Most of the hyper growth lies hidden in the long tail ( past).
Can you give us examples of the types of anomalies you refer to?
Our 4 year old is already very capable of recognizing anomalies between what we promised him vs. what we delivered. “If you want to really remember something, make a promise to a 4 year old”
Totally agree with this 
I don’t know if it’s the most valuable one, but it’s a very tiresome one to live with. You’d better quickly grow a sense of humour or you risk losing frequently.
Elaborate on this Paul. It’s very vague
