Do scientists hold back on releasing data? You bet, just as Dr. Shiller did. And the reason he did was not because he feared a visit from the Men in Black Labcoats, but because he wasn’t 100% clear he had the data to support his suspicion. Good science can be triggered by a hunch, but it can never be supported by one: there must be evidence. And many scientists withdraw or redact their pet hypotheses if the data isn’t checking out. Peer review happens, and if you aren’t perfectly sure your data supports your claim, you’re sunk. This is what is happening with Global Warming right now: scientists have reviewed a lot of the data and declared it junk or flawed. Now they want to see the rest of it, and it is “disappearing.”There's a lot of Junk Science to be found, especially when you look at the Global Warming scene. Some scientists are on the gravy train, and some are publicity hounds. But the scientific community in general is working more or less the way it always does.
Not sure what he does for a living, but I wouldn't be at all surprised if he were a scientist, or was trained as one. RTWT.
