Let's get this back on topic.
I ran across this really interesting article that seems to support my contention that, at least at an intellectual level, ethnically diverse collaborations seem to have a greater impact than more homophilous ones.

This is based on research that shows that academic papers with a greater ethnic diversity in family names have more of an impact than those from collaborations of people from what are more likely to be similar backgrounds.
The authors speculate that scientists may benefit from the multiple perspectives offered by people from different cultural backgrounds, and from the additional effort required to communicate between them.
This would seem to support the notion that a
permaculture community, even an ecovillage of two, would be more likely to be successful, especially if you were to be conducting research into novel ecosystems, with as much diversity as possible.
There's still a lot of work to be done on what makes the most effective scientific teams, and this probably also applies to
permaculture. In my case there are partnership arrangements that would result in greater conflict, not better collaboration. Some of the people in my life who I've got on best with have been
vegetarian Indians (although Sunder and I had a long and interesting discussion about cows one evening*); meat-eating Americans not so much. I'd probably last a fast ten seconds in a larger community, because of my own limitations.
Meanwhile I'm still looking for my
heterobi!sexual, heterophilous life partner-collaborator.
She'll probably turn out to be heterosexual autistic blonde middle-aged Scot, now (I ran across another paper that suggests that many neurodivergent people tend to mate assortatively and homophilously), but that might still work.
