1. Couch Potatoes A project to get college students off the couch and into the dining hall. Jimmy Chen & Alan Viverette, habits.stanford.edu

8. Finding #1 1 A predictor of participation was Facebook usage. The two subjects who used Facebook most frequently were the ones who were active in the study. Those that were not active used Facebook marginally more infrequently. This suggests that the channel is key – perhaps the same concept executed through email or SMS would have fairly different results.

9. Finding #2 2 When hot triggers are absent, there is a gap between online life and ‘real’ life. Subjects who read the daily menus could not act on them until later that day. One person commented that he forgot the relevance of the note by dinnertime. A physical component might help bridge this divide.

10. Finding #3 3 Small behaviors may not always have large impacts on behavior. Anecdotally, subjects stated that even though they were now more aware of the dining hall’s vegetable options, they already had fairly established eating habits.
