True, was responding to the comment more than the article. That "morale" is contagious does not seem to me to be a particularly surprising finding. Nor that a person's mental health can affect their working relationship with someone and that person's mental health. Anyone who has lead groups of people gets an intuitive sense of that pretty quickly. And I think the author is trying to put that intuition on a more reasoned footing, which I think is a good effort, but mental health is rather hard to measure quantitatively so it resists this form of analysis pretty strongly.
