@nina_kali_nina i think people in general feel like he contributed to biological research (https://arxiv.org/pdf/1805.03854) There's a ton of poor research, even AI led research these days. Plagiarised and falsified results. That hurts. Human subject based studies are sensitive, but they require ethics review board approval, and with that approval, I believe its perfectly fine to be a involved, I've done that. I wasn't the lead investigator, but I helped.
