Interest rates and business cycles
The Money Illusion.
We all have the tendency to look for evidence that supports our world view and dismiss items that run contrary. Here are a couple of posts by blogger Noahpinion, one on the general tendency for macro models/papers to have a conservative policy bias, the other a specific critique on the weak criticism by Tyler Cowen, of Marginal Revolution, on Keynesian economics.
As to my own confirmation bias, I once again say that those cheerleaders for the FED/ECB, US Economic recovery, and current valuations of the stock market are incredibly premature and most likely self-delusional.
Just saying its them -not me.
