Psychology
Psychology is the discipline that proposes testable answers to "why do people behave this way?" What separates it from self-help is that every claim is, in principle, backed by experiments, data, and replicable research — even as that research itself goes through periodic crises (the replication crisis of the 2010s overturned a depressing number of textbook studies, and the field is healthier for it).
We organize the books into three groups:
1. Foundations and overviews — These are written by serious researchers for non-specialist readers and represent the cleanest entry into the field: Daniel Kahneman's Thinking, Fast and Slow, Robert Cialdini's Influence, Steven Pinker's The Blank Slate, Lisa Feldman Barrett's How Emotions Are Made, Philip Zimbardo's The Lucifer Effect.
2. Clinical and therapeutic — Closer to the consulting room: Viktor Frankl's Man's Search for Meaning, Irvin Yalom's When Nietzsche Wept and Existential Psychotherapy, Bessel van der Kolk's The Body Keeps the Score on trauma, Marsha Linehan's Building a Life Worth Living on borderline personality disorder.
3. Applied self-development — The highest-risk category, where pop-science and real research are often only inches apart. We select on two criteria: claims must be sourced to academic work, and the author must acknowledge limits. Cal Newport's Deep Work, Mark Manson's Subtle Art, Carol Dweck's Mindset, Susan Cain's Quiet, Brené Brown's Daring Greatly.
Where to start: Thinking, Fast and Slow is the closest thing to a "you'll see the world differently after this" experience. If 500 pages feels too heavy, Influence is shorter, more practical, and you can apply it the same day. Don't start with The Courage to Be Disliked — its Adlerian framing is one interpretation among several, and starting there warps your reference frame.
What we don't include: MBTI, astrology, "read anyone in 5 minutes" titles. These are entertainment, not psychology.
