With current technology, it is impossible to tell whether survey respondents are real or bots. Among other things, makes it easy for bad actors to manipulate outcomes. No good news here for the future of online-based survey research

I personally think this is a "harder problem" than we care to admit.
So, are you a (social) scientist struggling with this situation? A break between what you _want_ to study (a causal process) and what you feel you _can_ credibly study (a correlation)?
Here are some readings that might help. 👇

Doing non-causal inference (and being explicit about it), yet using a causal word as second word in the title.
If you pay Nature € 10.690, they will publish this in Nature Ageing.
I can tell you what I think of that for free.
