How this list is made

Every week we ask the same 12 questions, 2 times each, of ChatGPT and Claude (both searching the web live) and Gemini (answering from what it knows; Google's terms don't let tools like ours analyse its web-search answers). The questions are worded the way readers really ask. We read which books each answer recommends, count each book once however it is spelled, leave out any book or author the question itself named, and rank by the share of answers that name it. A list is published only when every assistant answered.

This week: 72 answers (48 live, 24 from memory). Question set uk-1, run 5 October 2026.

  1. “What are the best business books I should read? Looking for ones that actually changed how people work, not just fluffy motivational stuff.”
  2. “I've never really read a business book before but I've just started managing a small team. Where should I begin?”
  3. “What are the best business books that came out in the last year or so? I'm keen to read something current rather than the same old classics.”
  4. “Are there any underrated or lesser-known business books that are actually worth reading? I'm fed up of seeing the same five on every list.”
  5. “My dad is about to retire and has spent 40 years running his own building firm. What business book would make a good birthday present for him?”
  6. “I've got a long flight to Singapore next week for work. Can you recommend a business book that's easy to get stuck into and won't put me to sleep?”
  7. “Can you recommend good business books about starting and running a small online shop? I'm just setting up in the UK and want practical advice.”
  8. “I loved The Lean Startup and want more like it. What other business books would you recommend?”
  9. “I've read everything by Simon Sinek and really enjoyed it. Which business authors or books should I read next?”
  10. “Our work book club is picking a business book for next month. Which one would get people properly debating and talking?”
  11. “What are the best business books by British authors? I'd like something with a UK perspective for a change instead of all the American stuff.”
  12. “I want to get my head around managing money and finances in a business. What's the one book I should read first?”

A list shows what the assistants said that week. It is not a ranking of quality or of sales, and nobody pays to be on it.
