Oh my

Oh my, not something specific to medical sciences:

… I know of people that have given a purportedly crippled software to a collegue to sabotage his project. I’ve been violently attacked verbally for having dared talking with my supervisor of a project I was collaborating with, because she feared that I wanted to “steal” her credit. I’ve seen more than once people “helped” during a project, only to find all credit for their work taken by the nice and smiling people who scammed them by “helping” them. There are endless horror stories like that. Everywhere.

The ones I’ve seen thriving in Cambridge, apart from geniuses (there are a few), are the guys who cling to a simple ecological tenet: Find your niche, where you are indispensable, and keep it in your claws at all costs. This means basically that these people do always the same thing, over and over again, simply because it’s the lowest-risk option. I could have done the same (I was pretty skilled during my Ph.D. in a quite obscure but interesting biophysics experimental technique) but I thought that doing science properly was also about learning and broadening your expertise. How wrong I was.

You can imagine yourself what does it mean also for research in general: Nobody takes risks anymore. Nobody young jumps and tries totally new things, because it’s almost surely a noble way to suicide your career.
