It's not even clear how they were recruited. Generation Lab says only that it was via proprietary methods i.e. they won't tell you. Why not? Is there anything so sensitive how they got in touch with students? Normally, polling firms are more open. It suggests they don't want you to know where their lists came from (could be as bad as MTurk).
