//chaotic stein anthology, february 23 "The thing about R^2 is that R^2 is r, squared." "R^2 is 53%. Nod your head, nod your head -- why are you nodding your heads? Shake your head, shake your head!" "I have a lot to say about this topic. I could talk for four hours about it. I could give a really good TED Talk about it. ... I could give 16 TED Talks about it." "There are certain things that Americans really like -- like guns, fast food, and rankings. ... That was really profound." "This was an obsession of mine -- arguing with Jay Mathews -- for a few years, and I even sent him a spreadsheet once."

#2: R^2 was not 53% but you could have easily thought it was, #3: regression to the mean and Sir Francis Galton, #5: the Challenge Index is horribly flawed // mod note: the challenge index sucks because it makes RM look better than us //mod note: that just means you're not taking enough APs, Andy
