Book reviews are only useful if you know how they were made. Here’s ours, in full.
We finish the book
Every full review on this site is based on a complete read. Not a skim, not a summary, not a podcast interview with the author. If we abandon a book partway through, we’ll either not review it, or we’ll say clearly that we stopped and why — that’s a review too, just an honest one.
We separate the idea from the execution
The most common failure in nonfiction is a genuinely good insight padded to book length. Those are two different judgements, and we make them separately: is the core idea sound? and did this book need to be this long? A five-star idea in a two-star book gets described as exactly that.
We tell you who the book is for
There is no universally good book. The Intelligent Investor is essential for one reader and a slog for another. Every review names the reader it’s written for — beginner, practitioner, or someone who already knows the field and wants depth.
Our rating scale
We rate out of five, and we use the whole range.
- 5 — Essential. Changes how you think. Worth reading twice.
- 4 — Strong. Genuinely useful, well-executed. Recommended without reservation for its audience.
- 3 — Mixed. Real value here, but padded, uneven, or partly wrong. Read the takeaways, maybe skip the book.
- 2 — Weak. One idea, overstated. Your time is better spent elsewhere.
- 1 — Avoid. Misleading, unsupported, or actively bad advice. We’ll explain precisely why.
A three is not a failure. Most books are threes.
How we handle evidence
For books making empirical claims — psychology, economics, health, anything citing studies — we check the load-bearing claims against the underlying research where we can. Popular science books have a well-documented habit of citing findings that later failed to replicate. When a book’s central claim rests on shaky evidence, that goes in the review regardless of how well the book is written.
Review copies
We accept review copies from publishers and authors. Accepting a copy buys consideration and nothing else — not a review, and certainly not a favourable one. Any review of a book we received free says so, in the review itself.
Affiliate links
Some book links on this site are affiliate links, meaning we may earn a small commission if you buy through them, at no extra cost to you. Commission rates are identical across every book we link to, so there is no financial reason for us to rate one book above another. Full details on our affiliate disclosure page.
Corrections
We get things wrong sometimes. When we do, we fix the post and add a note saying what changed and when. We don’t quietly edit. If you spot an error, tell us.
