NPR: Put Your Money Where Your Girth Is

I really enjoyed this Morning Edition story on “Prospect Theory,” or the idea that loss aversion can be an effective motivator in goals related to health improvement like weight loss and smoking cessation:

“What we know about incentives is that people work a lot harder to avoid losing $10 than they will work to gain $10,” explains Ayres. “So something that’s framed as a loss is really effective at changing behavior.”

Related to that question I was asked at Macworld: I wonder if a gym membership might be even more motivating if you received a daily email updating you on the wasted dollars you’d spent by not working out in the last n days.

When I started paying most of my own college tuition, I remember realizing that every class I skipped was equivalent to throwing away about a day and a half of the money I’d earned from waiting on tables. It was very motivating for me, and I started missing a lot fewer classes as a result.
