I find that there is something like a genotype/phenotype relation in Quadra placement. Generally, descriptions of Quadra are written in places, times, or by minds that skew what is written to one "phenotype", or expression, of the underlying genotype, which is quadra. Presumably then, Quadra itself is a set of values that cause an expression given some environment and is not the expression themselves. So whereas one beta may abhor violence and another may constantly willingly engage in it, only the personality-based (there are also environmental/"genetic interference"-based/etc, but these woule not be quadra) root cause of both of those attitudes is the shared quadral value.
