The complaint is that their data often doesn't strongly support the hypothesis, and dubious statistical techniques are performed to make it appear otherwise. And just poor statistics abilities (not malicious intent).
Physicists get away with it because they often just don't do any statistics. Often the data aligns so well with the hypothesis that you don't need any sophisticated techniques, or their work doesn't involve any data (like my example in my prior comment).
Most US trained physicists have never taken a course in statistics. It's not in the curriculum in most universities. When I was in school and would point it out, the response was always "Why do we need a whole course in statistics? We learn it in quantum mechanics."
No. That's probability you learn. Not statistics.
In social sciences (and medicine) people take a lot more statistics courses because the systems are much more complex than typical physics systems. A lot more confounding variables, etc. They simply need more statistics.
(Yes, yes. I know. There's probably some experimental branch in physics where people actually do use statistics. But most don't).
