I would say it's more because companies and other organisations are social systems, and your ability to succeed in a social system comes down largely to your social skills. I think people with poor social skills don't understand the importance of them, and therefor don't understand why the people with better social skills are succeeding, and subsequently come up with these post hoc rationalizations that allow them to explain these outcomes without confronting any of their own issues.
I'm not the parent commenter but I like your point.
People who have a reason to form a group will cooperate/collaborate best when they have some confidence in one another. People share ideas, projects, and skills, and "read" one another and form bonds. This is a social system. It could be a brief association or have a long duration. It could have a formal context, such as a business or a governmental entity.
Social interactions build people's confidence and sense of value in the group, in the individuals, and the work at hand. The challenge grows exponentially as the population of the group scales. Communication is hard.
An individual's discernment and connectedness (a confidence/value score) within the group will reflect potential for success. Communication matters.
The human plot twist is that there can be dysfunctional social systems as well as dysfunctional individuals.
You’re reading an awful lot into that person’s question. Social skills are a very basic concept, the wikipedia page for them gives a decent overview. But I’m skeptical that the parent commenter actually misunderstood what I meant, and instead wanted to engage in some debate about organisations valuing the wrong skills or something like that. A debate about the causes of social maladaptation is also not especially relevant to my initial point.
