Arguing with Zombies - Paul Krugman

The title of this book was coined to describe a specific kind of frustration: debunking a bad economic idea, watching it die in the data, and then seeing it shamble back onto cable news a few years later as if nothing had happened. Arguing with Zombies collects decades of

's columns and essays confronting exactly these undead ideas, tax cuts pay for themselves, austerity boosts growth, minimum wage hikes always kill jobs, and shows how each one keeps surviving contact with contrary evidence. Krugman's real subject isn't just economics. It's why bad ideas with powerful backers refuse to stay debunked. Here are 5 lessons from this book: 1. Some economic claims survive not because they're true, but because they're useful to someone. Krugman repeatedly shows that ideas like "tax cuts pay for themselves" persist for decades despite being disproven again and again, because they serve a political function regardless of their accuracy. Evidence alone rarely kills an idea that's protecting someone's interests. 2. Austerity during a downturn tends to prolong the very crisis it's meant to fix. Drawing on the aftermath of the 2008 financial crisis, Krugman argues that cutting government spending during a recession removes exactly the demand an economy needs to recover, turning a temporary slump into a longer, deeper one. 3. Inflation fears get invoked far more often than inflation actually materializes. Krugman tracks a repeating pattern of predictions, that a given policy will trigger runaway inflation, that consistently fail to come true, yet keep resurfacing as arguments against government spending almost regardless of the economic conditions at the time. 4. Healthcare economics defies simple free-market logic. Krugman argues that healthcare doesn't behave like an ordinary market, because information asymmetries and life-or-death stakes distort normal supply and demand, which is why market-based reforms alone rarely produce the outcomes their advocates promise. 5. Economic commentary needs to be held accountable to its track record. A recurring theme across the collection is Krugman's insistence on going back and checking who got major calls right and who got them wrong, arguing that economic punditry too often escapes scrutiny for predictions that simply didn't happen.
