Physics has moved towards a process based approach related to thermodynamics because it explains observations better. Biology has moved to a focus on evolutionary models and analyses because they explain observations better. Neither biology nor physics made this move in order to mimic the other. Economic analysis will make such a move if the explanatory, predictive, and perscriptive value of such a move is superior to what we do now. A weakness of EE follows from the fact that it argues for changes in the ways things are done for ethical reasons.
Political correctness is another matter.
To claim that economics needs to be just one part of how a problem is analyzed is one thing, a thing with which I agree. To say that economics needs to be replaced, etc. There is a world of difference between claiming that the discipline of economics carries too much weight in the decision making process, and claiming that economics does not study human behavior 'correctly' in some way. The former is a statement about the politics of academia, the latter demands a superior theory.
