I'm someone who finished a PhD, here's my perspective. You don't believe your supervisor or your research group and so you quit, great. It's great that you have the critical thinking abilities and confidence in yourself to make such a decision. However, I think it's extremely unprofessional to write a blog post saying that your supervisor is superficial or your research group is performative art. I don't say this bec…
Some light sometimes needs to be shed (look at Susan Fowler's post on Uber. I think it triggered a fairly necessary reevaluation, or Edward Snowden's revelations), but it is seldom without cost to the person that's holding the flashlight (Snowden is unlikely to receive a warm welcome, if he comes back to the US, and I suspect that Russia won't be a particularly joyful place, in the near future. I have no idea how Susan Fowler has done).
In my own case, my history (quite checkered) has given me some fairly unique views into a lot of terrible behaviors, rotten attitudes, and outright hypocrisy by many folks that like to project a wholesome, professional, image. Now that I'm out of the rat race, I could probably be more specific.
But I won't.
In some, rare, cases, perpetrators went on to cause harm (Not much. I never worked with John Wayne Gacy), but most ended up in rather unenviable places.
In a number of other cases, however, people ended up changing their behavior/attitude, and going on to be happier, healthier people.
For reasons that I won't go into here, I believe in second chances. I was given first-, second-, and third chances.
It has less to do with "professionalism," and more to do with being human. It's not my job to clean up the world (just the bits around me), and I need to pick my battles carefully, so I can do the most good.
