Mistakes were made
This is an admirable post by Matt Yglesias.
What I especially like is his willingness to conclude that his mistake in judgment on a specific issue was a product not merely of idiosyncratic circumstances, but of a structurally flawed way of thinking about the world, and specifically an over-willingness to trust elite opinion (this is especially impressive for for someone from Yglesias’ background, i.e. upper class Harvard grad etc.).
