Not even the Trump admin is alleging levels of indirect costs that high. See e.g.
https://grants.nih.gov/grants/guide/notice-files/NOT-OD-25-0...
"Yet the average indirect cost rate reported by NIH has averaged between 27% and 28% over time."
and a lot of that is simply because nobody wants to do the detailed accounting for things like: lab electricity usage, janitorial services, misc supplies.
> The result? 90%+ of academic science is fraud.
This is dramatic nonsense; a simple made up number.
