Personalities and skills impact a given team's success. Pretty sure this was already obvious. What is not addressed in this article is the implications of this. It might not be very PC to research or discuss how personality matters.
But if skills alone are not enough when hiring, then one implication is team's can't really hire blind - they will have to get into personality as part of the interview. I have seen people push for more blind hiring practices, that is to focus on grades, experience and skills and downplay personality or other character traits - but this doesn't appear to be a competitive solution. That also means all the workplace studies that don't include personality when comparing success in the workplace will not be telling the full story. Sorry I have no solutions, but I do see hiring based on personality or "fit" remaining a target even when it makes sense and is done appropriately and the right intentions.
