I work for a very conservative company, and based on my observations as a single guy, I think being married, or even divorced with kids helps your career, not by showing competency, but by showing you are relatively normal compared to the rest of society.
As a single male in my early 40's, I get the odd occasional question why I am not married with kids. I think they think I'm an oddball because I'm not in a relationship.
