Data behaves badly and it’s time we admitted it.

Data is a lot like teenagers and politicians: it has an uncanny ability to misbehave at the worst possible moment. You can spend millions on platforms and governance frameworks, yet a single rogue spreadsheet can still bring a global bank to its knees or derail a government’s pandemic response.

This book exposes the uncomfortable truth that data doesn’t always tell the truth. Even when it’s accurate, it can mislead, distort, or detonate when stripped of context. Surveys can be gamed, statistics can be bent, and AI for all its hype, is fundamentally engineered to make mistakes.

As the world drowns in zettabytes of information, the real challenge isn’t “data quality” but data veracity: truthfulness, reliability, and integrity in a landscape riddled with bias, noise, incompleteness, and error.

Data Behaving Badly is a guided tour through the chaos. A sharp, entertaining, and essential read for anyone who relies on data to make decisions. If you’ve ever suspected your data was plotting against you, you’re in the right place.

Welcome to the world of data behaving badly.
