If you’re interested in critical thinking and the remarkable ability of many people to delude themselves and others, it’s worth reading this short reference on crank magnetism, which may remind you of several people you know.

RationalWiki is a good resource for critical thinking and research on ideas and people you encounter. I’ve found it well written and have not found any obvious false or misleading statements in my occasional visits to the site.
