Don't hyperbolize. It's not all. It's something around 95-99% of "soft science" research done in the last 50 decades. The older research was better, back before we turned the fields into a mix of signalling games and money pumps.

But don't worry. In the recent years we've seen that apparently 90% of medical research from last few decades is likely bullshit too.

Most medical research isn't science either. AFAIK they're stuck at two sigma and one-off experiments as well. (Molecular biology and the like are a different topic.)
