You're absolutely right on both counts Pragma, regarding being thanked not meaning much and also doctors having limited understanding of stats, though obviously I have a very limited experience, and I'm not sure if my agreement means anything beyond my own immediate experience having worked in this lab for a few years. The lab has a very "medical school" feel to it. When I started out, I had to database maintenance stuff and I would have rather gouged my eyes out instead. Just the exact opposite of my interests and talents and all that. When I asked him if I could get involved with actual research that would lead to publication, he said something like, You know, everybody starts out doing "grunt work." Our postdoc is a very nice fella and he told me that I could help him with stats and that this would eventually lead to me having my name on a publication. I asked him why the female student who started out just a few months before me had a publication to her name, and he said something like, He (PI) is a traditional guy and has a "soft spot" for women. I'm not even sure what that means. Reverse sexism? He has a very professional relationship with her as he does with me and everybody else, although I do notice she gets "more interesting" tasks as times. But it's not we're in competition, we are not working on exact same project or same aspect of the project so, but anyhow.
As far as stats, you gotta see the PI's face every time our postdoc mentions stats. He looks like as if he ate something sour or is put in a very uncomfortable position and needs to escape. We have learned not to talk stats in front of him and focus on the big picture stuff. I still remember the confused expression on a volunteer's face when she questioned the validity of one of the main measures used in the study during the lab meeting and while looking at the PI who in response just looked at postdoc and made some vague gesture and then completely changed the subject to the timing of the next conference and if the poster will be ready in time.
I hate all these internal politics. I just want to sit in my corner, do the stats, write a paper, get published, etc. This stuff is very distracting and emotionally exhausting.
