First, it is simply not the case that “Brad DeLong speculates that Piketty himself would have answered “disagree” to the poll.” What he does is provide a quote by Piketty directly contradicting the content of what was suggested to the panel to be a Piketty position. This is rather different than “speculating.”

Second, yes, Piketty himself has now stated that he disagrees with the statement provided to the panel. Weissmann asked him, the most relevant part being, I guess “So this indeed has little to do with r>g” (Piketty!), see last paragraph here:

So, we have a) a quote by Piketty from before the panel session contradicting the panel question; and b) Piketty himself disagreeing with the panel question. The title suggestion that “No Economic Experts Agree with Piketty” is supported by nothing, at all – they were responding to a misinformation.

How ist it possible to not think, at this point, that the one who formulated this alleged Piketty position got it wrong, rather than your title conclusion? I’d also point out that you not only insulted Hoynes, but did so in a post in which you did not manage to get it right yourself.
