Collectivist Preference

"Artistic value is achieved collectively by each man subordinating himself to the standard of the majority."
--Ellsworth Toohey (The Fountainhead)

What Buck Sexton observes might be called collectivist preference. Collectivist preference can be seen as a person' penchant for complying with group demands and norms. It can be tied to both social identity theory and to institutional theory.

It would be interesting to measure collectivist preference. In fact, this has almost certainly been done in cultural research, since it is long known that some countries behave more collectivistically than others.

On a scale of 1 (low) to 10 (high), how might collectivist preference be distributed across a population? How might it vary between populations? 

The events over the past 18 months make me wonder whether collectivist preference is stable or does it evolve over time? What factors might influence collectivist preference? 

My sense is that collectivist preference may be more fluid than expected.
