Want to help everyone in your office or building eat healthier? Want to trick yourself into making healthier choices? Why not re-wire all the vending machines near you to give out only the healthy snacks and drinks, no matter what option a user chooses.
Sure, you might hit the vending machine for a little 3pm pick me up, but now it would be OK.
Stick a note on the healthy option that ends up being vended and set up a camera to see how people react. Maybe it’s the little push they, and you, need. If nothing else, it’ll make them think a little harder next time they go to push the unhealthy option.
