This two-book paperback bundle pairs an international bestseller on human folly with a practical guide to financial behaviour. The Psychology of Stupidity gathers essays from leading psychologists, including a Nobel Prize winner, on why clever people believe nonsense, while The Psychology of Money Mindset unpacks the beliefs and habits that shape our relationship with money. Together they make a thoughtful gift set for curious adult readers who enjoy accessible psychology with real-world application to everyday thinking and personal finance.. About the Books. The Psychology of Stupidity is an internationally bestselling anthology edited by Jean-Francois Marmion, bringing together sharp psychological minds - including Daniel Kahneman, Dan Ariely, Alison Gopnik and Howard Gardner - to examine why intelligent people fall for nonsense. Witty, wide-ranging essays explore lazy mental shortcuts behind poor decisions, why arguing with irrational people backfires, how online noise dulls our judgement, and why the least self-aware rarely recognise their own folly. It's a sharp, funny, genuinely useful look at everyday cognitive traps. The Psychology of Money Mindset turns that same lens onto our finances. Written to help readers decode the beliefs behind spending, saving, and investing, the book explores how mindset - not just income - shapes financial outcomes, offering practical strategies for a healthier relationship with money, navigating money conflict in relationships, and building confidence toward long-term financial goals. Read together, the two titles complement each other: one unpicks the flawed thinking behind everyday human folly, the other applies that same psychological insight to money. Both are approachable, jargon-free reads for general adult audiences, ideal for readers new to popular psychology or looking for a fresh angle on personal finance.. Two complementary paperbacks covering cognitive psychology and money mindset.. Bestselling editor Jean-Francois Marmion paired with money-mindset author Dr. N. Gosain.. Accessible, jargon-free writing for general adult readers.. Sparks conversation on decision-making, bias, and finances.. A thoughtful gift set for psychology fans and personal finance readers alike..
