6. What worked?
Just in time triggers
“It definitely helped that you sent the messages
right before I entered the dining hall.”
“Sometimes I would see them, but not clear
them so then it was like a 2nd alarm to order
the eggplant.”
“If I liked the vegetables I ate them because it
was there, but the days they served bad stuff it
just took up space on my plate”

7. What did not work?
Emails did not provide
social pressure! They
generally did not care about
the morning emails.
“The only reason I didn’t do it was because I
didn’t have room on my plate. There was no
reason not to. It was free.”
