Money Decision Index

The catalogue of the financial decisions people make every day, and the biases behind them.

Most money problems are not problems of income. They are problems of behaviour. Every entry names a decision you have probably faced, the bias driving it, and what to do differently the next time it shows up.

Example: Buying on the first price you see

The decision

You see something online for $389. Your card was charged $612.

What your mind does

It anchors to the first number and treats the extras as small additions.

What to do

Add all extras to the cart before comparing across providers.

SERVICES AND SUBSCRIPTIONS

Paying for a subscription you no longer use

Three months in a row, you have not used a service you signed up for. The $80 charge shows up anyway. You think about cancelling but tell yourself you will start using it again next month.

It feels like loyalty to your past intentions. There is a reason it isn't.
