How to tell a good self-help book from a bad one

Self-help is one of the best-selling categories in publishing and one of the least checked. A few simple questions sort the useful books from the confident ones.

Ask where the claims come from

A good book tells you whether an idea comes from controlled studies, from the author's practice, or from one memorable anecdote. A weak one blends all three into the same confident voice.

The replication crisis in psychology is worth knowing about here. Several famous findings, including ego depletion and power posing, did not hold up when other researchers repeated the experiments. Books built on them aged badly.

Books that have held up

• Feeling Good, David D. Burns — cognitive behavioural techniques in plain language. It has itself been studied as a treatment, reading the book as the intervention.
• Man's Search for Meaning, Viktor Frankl — a psychiatrist's account of the camps, and what he concluded about purpose.
• Thinking, Fast and Slow, Daniel Kahneman — the psychology of judgement, from the researcher who did much of it. Some chapters rely on studies that later failed to replicate, and Kahneman said so himself.
• Atomic Habits, James Clear — a practical synthesis of habit research. Useful as a toolkit rather than as science.

A rule of thumb

Be wary of any book that promises one secret. People who study behaviour change rarely find single causes, and the honest books say so.

What you could build here

Three directions that would work on this name. None of them is the only answer — it is your name once it is yours.

1. A curated review site. Books judged on evidence, not sales rank. A rare thing in a crowded category.
2. A book club or newsletter. One book a month, read properly and summarised honestly.
3. An affiliate storefront. Book buyers convert, and a trusted recommendation converts better.

What it could look like

A sample concept, built to show the name in use. It is a starting point, not a business that exists.
