The term “mansplain” has been coined to describe this: someone who talks as if he or she knows something – and does not listen to what someone else does know. It describes when someone dominates a conversation rather than having a dialogue. Women do it, too; but the term suggests men do it more. I explore reasons for this, including sources from the masculine end of the masculine-feminine continuum. A friend suggests that male birds attract and impress female with bright plumage. Lacking that, human males dominate conversations. I’d prefer plumage to mansplaining!
