Mind over Money: The Psychology of Money and How to Use It Better

Claudia Hammond is a Brit, so there are plenty of examples of British financial systems in this book. While this book does end with some "financial advice", it is done in a fairly tongue-in-cheek way.

Humans have an interesting relationship with money. Though money is an instrument for trading, the value attached to it is different from the value of goods it represents. People also attach a different value to physical money than to a credit card or abstract payment scheme. Burning money is seen as much worse than burning objects of a similar value.

There are also different psychological tricks to get people to part with money. People will base value on how something is framed. The middle priced item will often be purchased as it is better deal than the more expensive one, but better than the cheaper one. If a charity provides different "benefit levels", people will tend to donate that exact amount for the level. There are many other psychological quirks with humans and money that have been uncovered in psychological studies.
