Psychology Essentials Distilled

Most pop psychology is either obvious or quietly debunked. This gives you five robust ideas that explain a real chunk of human behaviour, each with a practical use, and it flags the famous results that failed to replicate. For anyone who wants the useful core without wading through a textbook or a TED talk.

Give me the 20 percent of psychology that covers 80 percent of what is practically useful for understanding human behaviour, my own patterns, and how to communicate better with other people. Focus on robust findings rather than popular theories that have not held up. Five ideas only, each explained in two to three sentences with a practical application. Flag which famous psychology results have failed to replicate.
