Hooked
by Nir Eyal
A product designer maps the four-step loop (trigger, action, variable reward, investment) that keeps you opening apps you meant to delete.
What does Reddit think of Hooked?
Hooked shows up in exactly the corners you'd expect: r/Entrepreneur, r/startups, r/gamedev, a scattering of book-request threads. Nir Eyal's four-step loop (trigger, action, variable reward, investment) gets cited as an X-ray more often than as inspiration. One r/Entrepreneur comment (↑67) uses it to explain why Reddit and Twitter validation loops work on people at all. r/gamedev takes the opposite angle: its top comment (↑16) recommends the book specifically so you can recognize the hook model and avoid building it into your own product. A single r/suggestmeabook thread (↑4) pairs it with Irresistible, calling one 'the guide to how to do it' and the other 'the book about how it's damaging us,' without picking a winner. Nobody argues the mechanics are wrong. People disagree about whether you should use them.

Who it's for
Read this if you build products and want the vocabulary for what you're already doing to users, intentionally or not. Founders in the r/startups and r/Entrepreneur threads treat it as background reading rather than a standalone plan, one item on a longer list that includes Rework and The Lean Startup. Care more about the ethics than the mechanics? The r/suggestmeabook thread's pairing with Irresistible is a better starting signal than the book alone. Product and growth people get more mileage here than general self-improvement readers, who don't show up in these threads at all.

Hooked — frequently asked
Is Hooked recommended for building products or for avoiding being manipulated by them?+
Both, depending which subreddit you ask. r/Entrepreneur's top comment (↑67) uses it to explain why social validation loops work, functionally a builder's read. r/gamedev's comment (↑16) recommends it explicitly so you can 'actively avoid adding that shit' to your own product. The book teaches the same mechanism either way; the displayed threads just disagree on what you're supposed to do with it.
Is Hooked just a shorter version of Irresistible?+
No. One r/suggestmeabook thread (↑4) presents them as a pair, not duplicates: Hooked as 'the guide to how to do it' and Irresistible as 'the book about how it's damaging us.' That's the only displayed comparison between them, and it treats them as complementary rather than redundant.
Does r/startups actually recommend Hooked?+
It shows up in startup reading lists more than it gets discussed on its own. The tracked r/startups mention sits inside a broader book-recommendation thread rather than a dedicated review, and with only one mention from that subreddit in seven years, there isn't enough displayed discussion to call it a community consensus pick.
Is Hooked worth reading if you're not a founder or product manager?+
The displayed threads don't really make that case. Every mention comes from build-something subreddits, r/Entrepreneur, r/startups, r/gamedev, not general self-improvement or book-request communities. If you're not shipping a product, there's no thread here arguing you need Eyal's framework anyway.
