Something to consider is that the feeling of being an imposter could also be the fault of a toxic work culture; the OP alludes to that by calling out the “real programmer syndrome”.
This piece points out that “syndrome” implies the fault is within the individual having an imposter experience, and causes people to not consider the structural issues that contribute to poor mental health: https://qz.com/work/1286549/imposter-syndrome-lets-toxic-work-culture-off-the-hook/
“One of the psychologists that coined imposter syndrome, Dr. Pauline R. Clance, once said that she wishes she called it ‘imposter experience.’” I love this.
Nightmare-level on-call rotations definitely add fuel to the fire of “real programmer syndrome.” You’re not only expected to stay up all night for an entire week, but you’re supposed to recount your war stories in a way that makes you sound like the hero.
Given the number of job applicants that can’t even write FizzBuzz, is it really impostor syndrome or are the people responding to this survey perhaps actually as bad as they think they are?
‘Do you suffer from impostor syndrome’ is a ridiculous question anyway. The whole point of impostor syndrome is that you think you’re out of place and everyone around you knows more than you. If you know you have it, you don’t have it.
I would be surprised if people that are genuinely out of place, genuinely aren’t capable of doing what they’re meant to be doing, and have Dunning-Kruger syndrome are likely to respond ‘yes’ to this survey as well, based on them occasionally realising how out of place they are then chalking it up to impostor syndrome.
Also what the hell is that graph in the middle? Where’s the section where it shows the people that responded with ‘no mental health issues’?
