Martin Seligman

Who

Martin Seligman (born 1942) is an American psychologist and professor at the University of Pennsylvania. He is the founder of positive psychology and a past president of the American Psychological Association (1998).

Major Contributions

Learned Helplessness (1967)

Before positive psychology, Seligman discovered learned helplessness — the phenomenon where animals (and humans) exposed to uncontrollable stress stop trying to escape even when escape becomes possible. This became a foundational model for understanding depression and later inspired his turn toward learned optimism.

Positive Psychology (1998)

As APA president, Seligman declared positive psychology the theme of his presidency, arguing that psychology had become overly focused on pathology and disease at the expense of studying what makes life worth living. This is widely considered the formal founding of the field.

Authentic Happiness Theory (2002)

Proposed three pathways to happiness:

1. The Pleasant Life (positive emotion)
2. The Good Life (engagement and flow)
3. The Meaningful Life (belonging to something bigger)

PERMA Model (2011)

Expanded to five pillars: Positive Emotion, Engagement, Relationships, Meaning, Accomplishment. See [[perma-model]].

Positive Psychotherapy (2006, with Tayyab Rashid)

Operationalized PERMA into a structured clinical intervention. Sessions target each PERMA element through exercises like:

• Using signature strengths in new ways
• The gratitude visit (writing and delivering a letter to someone never properly thanked)
• Active-constructive responding (enthusiastically engaging with others’ good news)

Shown effective for depression in multiple RCTs. See [[positive-psychotherapy]].

Comprehensive Soldier Fitness (2008–)

Applied positive psychology principles at scale through the US Army’s resilience training program, teaching ~1 million soldiers skills in emotional fitness, social fitness, family fitness, and spiritual fitness.

Philosophical Stance

Seligman argues that psychology’s traditional disease model (treating mental illness to get from -10 to 0) is insufficient. Positive psychology aims to get people from 0 to +10 — not just reducing suffering but building flourishing. This is a central premise for understanding how [[happiness-therapies]] differ from traditional clinical approaches.
