Reasonable decisions, regrettable outcomes

Bad financial decisions rarely announce themselves. They arrive dressed as common sense: paying off the wrong debt first, holding too much cash, avoiding insurance because nothing has happened yet, chasing a 'sure thing,' or treating a complex problem with a simple rule. Each feels prudent in the moment. Each is a predictable error that behavioural finance has named, and that costs families dearly precisely because it doesn't feel like a mistake.

Perfectly Logical is a tour of the reasonable-sounding decisions that quietly do the most damage. It draws on behavioural finance to reveal the biases behind them, walks through the specific 'logical' choices that most often backfire, and gives you a practical defence, the questions and habits that catch a comfortable error before it becomes an expensive one.

What's at stake

Four 'logical' choices that backfire

Comfort over correctness

Decisions that feel safe, like hoarding cash, quietly erode wealth.

Recency reasoning

'Nothing has gone wrong yet' is treated as proof nothing will.

Oversimplifying

Complex situations get one-size rules that don't fit them.

Confident error

Smart people trust their judgement most exactly where bias hides.

This book will challenge your confidence, gently

It's not about being foolish, it's about being human. The smartest readers benefit most, because intelligence is no defence against bias; awareness is. Read it on your own decisions, not just others'.

  • For confident, capable decision-makers
  • Intelligence is no defence against bias
  • Apply it to yourself, not just others
  • The dangerous errors feel perfectly reasonable
“The decisions that cost families most never feel reckless. They feel perfectly logical.”
