Proof

For over two thousand years, from the Medieval Arabic world to the midst of the covid-19 pandemic, scientific progress has relied on different methods of establishing fact from fiction. Achieve logical perfection, the reasoning went, and you would be rewarded with ultimate, universal truth.

But there is far more to proof than axioms, theories and laws: when demonstrating that a new medical treatment works, persuading a jury of someone’s guilt, or deciding whether you trust a self-driving car or a financial transaction, the weighing up of evidence is far from simple.

In Proof, bestselling author, statistician and epidemiologist Adam Kucharski spans science, politics, philosophy and economics, to explore how truth emerges – and why it falters.
