Why do so many otherwise rational individuals make irrational decisions when it comes to money? Why do shoppers overspend when using credit cards, but manage to stay in a budget when they use cash? And why would a person walk five blocks to save $10 on a $20 purchase, but not on a $1,000 suit?
“Our brains evolved to make decisions on the savannah or in a jungle. And a lot of the decisions we have to make as adults in a modern world aren’t necessarily applicable to what we might have made 10,000 years ago. The decisions aren’t crazy; they are simply obsolete.”
–Gary Belsky on irrational spending behaviors
