Under the title “Academics drag feet on giving out data” Lott quotes extensively from an article about the hockey stick by Steve Milloy. One part Lott doesn’t quote is this:
Well, a scientist’s refusal to provide colleagues with his data and methodology is suspicious.
Now, Milloy is being deceitful by implying that Mann, Bradley and Hughes hadn’t published their data and methodology when they had already done so, but it is true that refusing to provide data and methodology is suspicious. As done by, to pick a name at random, John Lott. I guess that if Mann had claimed to have lost the data in a disk crash Milloy would not have breathed a word about the matter.
