I reviewed articles for two scholarly journals yesterday, one of which was quite good and one of which had a very good empirical analysis embedded in a badly biased introduction and conclusion.
It becomes more and more challenging to maintain my equanimity as I review articles which have such clear implicit — and, frequently, explicit — biases. In fact, not long ago my frustration boiled over onto Twitter and I nearly got in trouble for violating the confidentiality of the peer review process.
