This is such a big thing Ive seen over the years.

People simply dont know how to think logically. And many people cant take criticism or feedback. So they cant think, and they dont improve because they cant handle feedback. They take feedback as a personal attack and just ignore it.

• learn how to think from tv / movies
• no interest in serious self education
• many people think they know it all
• barely research subjects they claim to know a lot about

Society is really becoming heavily handicapped by these things.

If you wanted to know a lot about subject XYZ you'd need to read 2 or 3 books and watch several documentaries - at a minimum. That would be a good START. Most people do 10% of this, and think they know it all.
