Which is often the right thing to do unless you have very specific knowledge of that experience e.g. a referral, because so many people flat out lie about their experience and accomplishments. If you can't directly verify it, the accuracy is so low it's best ignored.
As for your experience, I'm glad to hear you're now happily self employed (so am I!). How are you proving your skills to customers, if you can't handle job interviews? Or are you making a product?
"Have you considered that you might not have a full understanding and appreciation for human psychology and the wide variance among humans?"
I have an average such understanding, having lived an average life. But the problem remains: someone who claims to be able to do a job fine but can't demonstrate that capability when asked, is from an employer's perspective best avoided. That isn't a flaw in the interviewing process, that's the point of it! The reasons why someone can't demonstrate it are irrelevant because there's no better alternative available, and anyway, someone who can't handle the pressure of a job interview is very likely to crack in other situations. You claim it's not true and there's something psychologically unique about interviewing, but, I don't really believe this and clearly neither do other people doing hiring.
