Another aspect of playing the game unfortunately. There is some give and take I have to accept with playing-to-win and playing-for-education. First, studies are very hesitant with their results (and justifiably so, because they are just one study). The unifying analysis of one author is thus much more persuasive. Much more importantly in my experience, its really hard for me to read excerpts from a study to someone because the material is far more technical and harder to understand for a listening audience.

edited for clarity.
