Quadra, a truncation of the word quadrant obviously. What has four quadrants? The Star Trek galaxy of course. Alpha, Beta, Gamma and Delta. A bit more down to earth and we have four quadra’s in society.

A quadra could also be known as a small group “compatible dynamics” model. That is, four sets of four psychological types whom share relations deemed by the community as most understood, comfortable and psychotherapeutic.

Relations outside of a quadra tend to have some degree of misunderstanding, irritation, annoyance or simply tiresome.

It may not seem apparent at first although as time goes on in relations between types you may rationalise that in fact I do get on well with so-and-so who shares the same quadra.

Conversely you may find that somebody from another quadra may hold less interest for you even if you consider them a good friend.
