Despite his dubious past, the billionaire John Arnold has focused time and money to amend scientific research. I've read maybe 2 years ago about that endeavor and followed him on Twitter ; I found it quite interesting and original. For example, he offers researchers to save their initial data (before any screening) so that other researchers can check which cases were thrown out of the study. He also funded reproduction tests. I haven't followed since, so I hope he kept on doing good work.

This is my first time learning about him and haven't been exposed to much more than the wikipedia article - what about his past is dubious?
