The big breakthrough, of course, was they had data. That's what changed everything. Before 1960, there really wasn't research quality data that you could test very many hypotheses.
David Booth
And with that, then it's hard to refute the arguments. These are what the data show. This is it. You can argue that you don't like the data, but this is the data.
David Booth
I believe it and I have data. You don't believe it and you don't have data. Once you get some data, come back to me.
