More commitment strategies – for humans and birds!

From Yale psychologist Paul Bloom:

As I write this article, I’m using a program that disables my network connections for a selected amount of time and does not allow me to switch them back on, thereby forcing me to actually write instead of checking my e-mail or reading blogs. A harsher (and more expensive) method, advised by the author of a self-help book, is to remove your Internet cable and FedEx it to yourself—guaranteeing a day without online distractions.

Even pigeons can craft commitment strategies.

Ainslie conducted an experiment in which he placed pigeons in front of a glowing red key. If they pecked it immediately, they got a small reward right away, but if they waited until the key went dark, they got a larger one. They almost always went for the quick reward—really, it’s hard for a pigeon to restrain itself. But there was a wrinkle: the key glowed green for several seconds before turning red. Pecking the key while it was green would prevent it from turning red and providing the option of the small, quick reward. Some of the pigeons learned to use the green key to help themselves hold out for the big reward, just as a person might put temptation out of reach.
