Can confirm. My PI didn't review anything. Sent their journal reviews to students and told us to sign their name at the bottom. Straight up told us to falsify our results on more than one occasion (I refused). I reported them to admin. Admin didn't investigate, didn't even contact the witnesses I named, and gave the professor tenure. This was at UT Austin about ten years ago. Academia is broken.
I know, I'm in academia. But this silence is why these things keep happening. PIs hold power over their students to keep them in line, through letters of recommendation to networking and post doc/job offers. We need to work to correct that.
And this is why it's expected that the PI will take responsibility for any papers published by their lab – if the PI isn't doing their job, they should face the consequences.
Maybe I just don't understand biology, but there seems to be something up here.
