psychology by psychologist

A lot of the good stuff sort of comes from reading and interpreting papers directly, but discussions and material on those papers can be equally great

Some of my favourites reads are Obedience to Authority (Milgram) and Beyond Freedom and Dignity (Skinner). They are a bit on the dated side, especially Skinner, since he was the last of the radical behaviourists and still had a locked-away view of cognition, but he paved the way for Bandura and his Triarchic theory, which was a great step into a nuanced point between the tensions of the medical model and the psychological/social models. Eysenck's work on memory and personality, Seligman on happiness and Dominic Murphy on the philosophy of delusions('Psychiatry in the scientific image' I think) are also great
