Do You Spend Like a Baboon?

A great animated video explaining our evolutionary ability to process numbers, and why it’s a hazard to our wallets.

Beginning with babies, researchers demonstrated how they visualized simple math equations and proportions. Neuroimaging in adults also revealed which areas of the brain process representations of numbers and math equations. Further investigations showed that animals process numbers in similar ways.

The way we view numbers affects our spending habits, because it’s difficult to tell the difference between small differences in numbers. Our decision making is using the same evolutionary circuits it did when it didn’t need to process such complex amounts, and may be costing us money.

Based on research conducted by Karen Wynn at Yale University.
