Do you think that this affects any other area of science, and if so, is this effect equal to that in the social sciences? One area I can think of is in topics such as String Theory, where there is a lot of current discussion going on and many different ideas. Could this broad list of options open this area of physics up to similar risks from studies that cannot be replicated?
As I see it a "study" as used here is some form of experiment. There are no experiments (or damned few) that apply to string theory as yet. It is all very interesting mathematics.
The math is checked very rigorously (no one wants to publish and find they didn't carry the 1) so I doubt that this is a serious issue in that field.
