Openness 92%Something I am always wondering about is whether polyamorous folk I know have qualities that stand out as common among them compared to monogamous folk. Openness is the obvious personality trait that comes to mind. It does seem that polyamorous people have greater openness than most. That could be because being in a minority that are doing things that are socially quite different to the majority engenders greater openness, or people with greater openness are more likely to have polyamorous ideals and attachment styles, or both or more!
I found an article that speaks about this: Are Some Personality Traits More Common in Polyamorous People? Its short but interesting.

I suspect openness may be one of the things that makes polyamory easier because dealing with the ups and downs of maintaining multiple intimate relationships benefits from the capacity to take in other people's perspectives and ideas.
