> competence is often inversely correlated with charisma

Source needed. I've been working in tech for 15+ years, alongside highly charismatic and competent people, terrible engineers with less charisma than my coffee pot, and everything in between.

You do not need to be charismatic to be a good engineer, but also it certainly doesn't hurt, and friendly teammates make for a better team atmosphere. If I'm considering two candidates otherwise similar, I'm going to go with the one that's more pleasant to work with.

If we assume they are two normal distributed characteristics that aren't related, then it is a natural consequence once you select for those who are at the top of either distribution.

Someone in the top 10% of competency or charisma will have average distribution of the other. If you consider the full population, you'll find no relationship, but because you are only look at the top 10% of each, those in the top 10% of one will be average in the other and vice versa. While some (~10% of each top 10% group) will be represented in the other group, you'll still find that they are more likely to be at the bottom of the group in the second group.

The end result is that if you only plot the data for the top 10% of each group, there will be an inverse correlation.

This can hold true even if there is a positive relationship between the two characteristics depending upon the strength of the relationship and how selective you are in selecting the top of each group.

This leads to some interesting results, such as when fruits are grown for look and shelf life risk losing taste and flavor despite these factors being unrelated.

Of course you want to work with people who are "pleasant" and "friendly" but these are not synonyms for "charismatic", defined as having "special magnetic charm or appeal". [1]

Would you disagree that software development, as a profession, tends to have fewer charismatic people in it than other fields in which charisma is more valuable and/or essential? For instance, if I were to suggest that the average successful politician is more charismatic than the average successful software engineer, would you disagree with that statement?

If we think about it in purely economic terms, I'd suggest that people who are very good at getting other people to do things (i.e. they have charisma) have a powerful incentive to enter careers where they can leverage that special ability.

Maybe charisma is the wrong term. I've found pleasantness and willingness to communicate to be strongly correlated with engineering ability amongst those in the profession. Likewise, the worst engineers I've worked with all had major anti-social personality issues. The profession has always involved soft skills in my experience. When I've hired people I designed small tasks similar to the actual day-to-day work they would be doing, and that filtered out candidates who lacked coding ability quite easily.

Experience and observation. When one is deeply involved in solving hard problems, one has less time for pleasantries, superfluous stuff ( but important to people in general) and subtle manipulations of relationships, that make up 'charisma'. Over time that becomes your personality. Not saying that this is the best thing to happen to an engineer, but it's the way things are IMO.
