Ideology certainly plays an important role in generating false hypothesis, but all the observational sciences suffer from the problem that you can't run experiments to rigorously test the robustness of your hypothesis.
In the experimental sciences you can get far using the rule of thumb that if you need statistics you did the wrong experiment, while in the observational sciences the use of statistics is inherent.
