Definitely this. I find that insecurity also correlates strongly with the above description.
edit: wow down voted into oblivion over this... I came for a reasonable debate. Its super clear now why "rude" people rule and all the passive aggressive do is down vote me over a reply.
Most of the time: the guy that’s going to leave an overly clever undocumented, unmaintable mess. Bonus points if it’s in a language that none of the rest of the company uses.
Contemporary development is a team sport.
In the case where the individual truly is more talented they don't need to profess it aggressively. It will be quite clear in feedback from colleagues to their boss and by the quality of the their output.
That is different than a control freak that refuses to leave other peoples work alone.
How would those 7 top performers act if placed alone in a situation of failure? Where its obvious the company is failing and is clear is certain individuals? Is it not "rude" to point that out? Or are we defining being rude or assholity differently?
I personally seen many times people who push back or raise justified criticism of anything be labeled as "rude"/"toxic"/"assholish".
I mean, I find it very natural that one would overestimate the qualities of the people he likes, und understimate those of who he dislikes.
Totally agree, although the trickiest times in my career haven't been when some IC is convinced they are a top performer and everyone should follow them, but when that person's manager also thinks the same. When it's both, it's almost untenable, as going to that person's manager makes some think you're a complainer going that high up the management chain.
I thought I was an asshole, but then when I read descriptions of assholes vs descriptions of not-assholes I think I fall under the latter
In contrast, the top 7 performers I can think of off the top of my head were to a person kind, generous with their knowledge, patient with those less talented, and generally Good People, both to work with and to be around in general.
So there's my anecdote to counter yours.
I will note that although I have never met an asshole who was a top performer, I have met many who were convinced that they were.
