I think that certain personalities are more likely to develop certain skills as well, but not in an archetype kind of way. It has something to do, that people can see in communities around certain technologies, such as programming languages or databases. Idioms that develop result in certain ways of thinking, and often those are considered traits about a technology, when they are actually traits are mostly caused by the community, for example, but not only because certain techniques are applied. When someone for example compares C with communities around more modern languages you see that C has a way more fragmented community and despite people agreeing that C per default doesn't come with strong security measures you know that in the OpenBSD, djb, Colin Percival, community despite all of them using a lot of C you can find extremely secure communities. Of course one might argue that they also develop technologies around that, but then again, that's a community led effort and not a strength of a community. For personalities it appears that certain personalities or rather constellations of personalities, be that around an open source project or in a company lead to certain "values", that even when they are not outspoken and maybe not even thought about push things into a certain directions. I think that constellations of people might even be more important, as I've more than once seen people and personalities behave differently in relation to other people. To give an example, a programmer can have certain values and have a set of technologies that he commonly uses to approach certain problems and might be the perfect developer for the team, the same person might do a horrible job, because of being too opinionated, despite having the general knowledge for leading a team. Of course one might equal that to bad team leading skills, as the person is unable to let these things go, and that might be true, but then which personality trait isn't also a skill?
