The new era of positive psychology

Martin Seligman, University of Pennsylvania psychologist and former president of the American Psychological Association, announces the birth of a new field: positive psychology. After decades of psychology focused almost entirely on mental illness and human malfunction, Seligman argues that the field must also develop a rigorous science of human flourishing — of what makes life worth living for healthy people, not just what reduces suffering in sick ones.

Key Arguments

1. Psychology has been asymmetric. For a century, psychology has focused on pathology — depression, anxiety, schizophrenia — and done so brilliantly. The cost is that it has largely ignored what makes life meaningful, what produces genuine happiness, and what allows ordinary people to thrive.
2. Three routes to happiness. Seligman identifies three empirically distinguishable orientations to a good life: the pleasant life (maximizing positive emotions), the engaged life (using signature strengths to produce flow), and the meaningful life (using strengths in service of something larger than yourself). The engaged and meaningful routes predict lasting wellbeing more strongly than the pleasant life alone.
3. Character strengths can be identified and deployed. The VIA (Values in Action) Character Strengths survey identifies 24 universal strengths that cultures across time have recognized. Using your top strengths in new contexts — especially at work — reliably increases engagement and satisfaction.
4. Three Good Things exercise. Each night for a week, write down three things that went well and their causes. This intervention, tested in randomized controlled trials, has produced significant reductions in depression and increases in wellbeing that persist six months after the intervention ends.

Evidence Context

The Three Good Things intervention is one of the most replicated positive psychology exercises, with consistent effects across multiple trials and follow-up periods. The broader PERMA model (Positive emotion, Engagement, Relationships, Meaning, Achievement) that emerged from Seligman’s subsequent work has generated a large applied research literature. Some critics argue that positive psychology initially oversold the strength of its effects, and the replication crisis has affected some studies in the field. The exercises Seligman highlights in this talk, however, have held up relatively well under scrutiny.
