Experimental Design
Experimental Design
For a weight loss experiment, we allowed students to opt into one information treatment or one no-information treatment (the details of which we prefer not to disclose at this stage).

Pairing for standard experiments such as dictator games is randomized among students, with names and majors revealed to each other.
Experimental Design Details
Randomization Method
in office by a computer
Randomization Unit
Individual students
