This was my take as well. At least microeconomics has moved away from large-scale observational studies and has moved into experimental and quasi-experimental studies.

While the methods alone cannot fix it all ("You can’t fix by analysis what you bungled by design" [1] after all), it gets somewhat closer to unbiased results.
