Psychoanalysis, Milgram’s Obedience Study, Pavlov’s Dogs, and Beck’s Cognitive Therapy? Sure, you know what they all mean (that is, you’ve certainly heard of them), but do you understand enough about these psychology theories to join a dinner party debate or dazzle the bar with your knowledge?

30-Second Psychology takes the top 50 strands of thinking in this fascinating field, and explains them to the general reader in half a minute, using nothing more than two pages, 300 words, and one picture.
