Super interesting theory. I think the implication here is a little bit unnerving though: if an individual has three "weird" views, and the most effective way to convert another individual is to only expose them to one of those three, then are we doomed as a society to evolve at a slow pace, since humans are just not psychologically prepared to comprehend so many new ideas at the same time?
Yes that slows the rate of change, but the rate of change adjusts based on the times (and hopefully it’s reasonably optimal but that would be hard to measure objectively because it’s a complicated risk-vs-reward, explore-vs-exploit trade-off). Eg Historical revolutions usually saw rapid changes in many areas like politics, art, culture, technology. Societies (like organisms and ecosystems) are extremely complicated so there are serious risks to evolving too fast so slow isn’t automatically bad.
