 In the cafeteria example while aware that the food is on different levels the students are not aware that the placing of the food has been done in order to promote a certain end—eating more healthy foods. The placement of the food is not random, nor motivated by aesthetic considerations. It is deliberate and motivated by a particular set of considerations. Some nudges are more transparent in the sense that it is obvious they have been deliberately introduced and their motivation is also clear. For example, the warnings on cigarette packages that smoking is dangerous to one’s health. Call these broad nudges.
