Cover of “Spot the Flaw”

“Thousands of customers can't be wrong.” “We've always done it this way.” “Sales up 400 %!” Every day someone tries to convince you of something – in ads, meetings, family chats and headlines. Most arguments are fine. Some only look convincing. This workbook trains you to tell the difference – calmly, fairly and with plenty of practice.

Part 1 shows what an argument is – claim, reasons and the hidden assumption between them – and starts with a self-test. Part 2 explains 24 common flaws in five families, each with a plain name, its textbook or Latin name, a typical example and one question that exposes it. Part 3 mixes everything: tests without hints, longer texts with several flaws, and advice on how to respond without starting a fight.

No politics, no religion, no real people or brands – just clear thinking for everyday life. In the paperback there is room to write in every worksheet; in the e-book, every worksheet is a numbered list linked to its answers.

What is inside

  • 24 flaws in five families: relevance, evidence, cause and consequence, language and structure, numbers and chance
  • 300+ exercises with invented everyday examples: name the flaw, match, multiple choice, sound or flawed, rewrite the argument fairly, write a calm reply
  • Plenty of sound arguments too, so you learn not to see flaws everywhere
  • A self-test, six mixed tests and three longer texts – a team meeting, a flyer, a forum thread
  • A four-week plan, a complete answer key that explains every answer, and a quick reference with all 24 flaws
