To be a brilliant jerk (BJ) is a social phenomenon. I think everybody (brilliant) is a BJ sometimes. In academy one does that to protect own field of research, or virtue signalling. A BJ can recognize a good idea and use it later without attribution (and perhaps in a better version, because he's brilliant). A BJ can bark at the stranger's idea and later become a supporter of the same idea, done by one of the friends. So in conclusion I think it is not constructive to NOT listen a BJ, instead treat them like an evolved form of a troll, face them with evidence and do what they don't: learn their field.
