You can substitute the word openness for creativity in my post, it doesn't really change the argument. The words are made up anyway, they did a factor analysis over lots of questionnaire responses and then found the largest contributing factors. Then they kind of eyeball the questions and tried to come up with a word that described the kinds of questions in that cluster. Openness is prob more accurate, but creativity is more readily understood and close enough to be used when trying to convey a message imo.
I know how the Big 5 model was developed. Creativity is more complex than just openness. Needing new experiences everywhere is novelty seeking. It's more complex than openness too. And openness distributions for software developers and everyone else are about the same as far as I know.
Creative people can thrive in many companies. You're right startups tend to be good for novelty seekers.
Your condescending tone tells me that you are likely just the sort of person the OP is having trouble with. And they are everywhere in software development.
