About this book
Crime, school cheating, and even parenting look different when the obvious explanation keeps failing. This book turns everyday puzzles into a clear view of the hidden side of everything, where incentives matter more than common sense.
What you'll learn
- Identify hidden incentives in everyday systems, so you can spot why people may act against the obvious interest of the people they serve.
- Distinguish correlation from causation, so you do not mistake a convincing story for a sound explanation.
- Use data patterns to test surprising claims, so you can look for measurable signs of behavior that people would rather keep hidden.
A taste of chapter 1
Chapter 1
The book starts with a simple posture. Most social outcomes arrive with an obvious story attached, repeated so often it feels like an answer. The method here treats that story as a first draft. The real question is why the surface explanation might be wrong or incomplete, and what is happening underneath that people prefer not to see, cannot see, or are paid not to notice. That hidden side is not mystical. It is built from ordinary motives, uneven knowledge, and sloppy measurement.
That shift in posture looks like this.
The opening framework is a working lens, not a grand theory.
Incentives: what people want and what rewards or penalties push them, including money, status, approval, and moral self-image.
Information asymmetry: who knows what, who cannot observe what, and who can hide what.
