So it's been revealed that Blanchflower is a friend of Peter White (bravo to those who found it, I checked for associations myself but missed it by checking only Wessely and Sharpe

), hence his bizarre obsession with PACE (rather than the general psychosocial debate).
Unfortunately he seems to have a large following. I have seen at least one retweet (a particularly nasty one at that) from well-know economist Brad DeLong, who has a much larger audience. Blanchflower blocks anyone who shows him wrong, though, so don't bother. He's mostly limited to insults and name-calling so far, with a good dose of logical fallacies.
Similar to what we have seen with the Cochrane reactions from seemingly random people, who mostly turned out to have been connected to some of the PACE team, or the weird ideological whatever-it-is at Spiked.
Normally this would be the work of the SMC. Instead this seems to have been a personal appeal from White to his friend(s). It seems pretty emotional and personal so I wonder if the tides are turning behind the scenes and the team is starting to fear accountability could befall them. As they should, frankly, the principal investigators' career will not recover once the scandal finally breaks open.
