The work and edition history

Jonathan Haidt’s 2006 book considers ten ideas about living well in relation to psychological research. His own description presents it as an encounter between older wisdom traditions and contemporary questions about happiness and meaning.

Psychological reading

For each Great Idea, ask three things: what did the old tradition claim, what study does Haidt set against it, and does that study test the idea or only illustrate it? When ancient advice and a modern finding agree, is that confirmation or selective matching? What would it look like for a study to contradict an old maxim?

Why it earns inclusion

A bridge between philosophical accounts of a good life and the psychology of happiness (section 14.5 is a candidate link, not confirmed). It is useful for asking how a vague maxim becomes a testable hypothesis.

Academic pairing and claim scope

No research paper is paired. The studies Haidt cites inside the chapters were not inspected.

Limits and controversies

This profile rests on the author's page, catalog records and a short reference summary, so no study or claim inside the book is checked. A match between an old maxim and a modern finding is an interpretation, and the author's description of his own book is not independent evidence.

Evidence behind the claims
