The summary I quote below represents the paranoid or less-successful-than-they-want-to-be professor. There are many at all levels of success and career development have literally devoted their lives to ideas they think will change the world if implemented. I've heard of people "scooping" ideas, decade long blockades on ideas, etc. People fail to cite the right people. Is that because they don't want to share glory or because it's not easy to keep up with research? The phrase "success has many fathers failure is an orphan" comes to mind.

----- he thinks his ideas are very important;

he thinks he doesn’t get as much credit as he deserves (especially for those important ideas);

he interprets in unflattering, even dark, terms the motivations of people who seem to keep him (or his relatives) from getting credit;

he strains to see pattern where it may not exist.
