Steven Pinker concludes this observation (on p. 366) saying that:
"A more rational approach to politics is to treat societies as ongoing experiments and open-mindedly learn the best practices, whichever part of the spectrum they come from. The empirical picture at present suggests that people flourish most in liberal democracies with a mixture of civic norms, guaranteed rights, market freedom, social spending, and judicious regulation."
"Reason tells us that political deliberation would be most fruitful if it treated governance more like scientific experimentation and less like an extreme- sports competition."
I wholeheartedly agree with him.
