High trust in society correlates strongly with being anti-innovative. Europe is going through another lost decade in a row because it got too addicted to social democracy. The fastest growing parts of Europe are some of the lowest trust (i.e. Poland). Please fleece the tax payer more.
More fun always come with more risk. Everyone has their own threshold. So it is pointless to say that "Boring is good". It might be good for you, but not for everyone.
Boring, high trust societies are conducive to risk taking. High trust reduces transaction costs. And people are more likely to take risks when they can trust the system under their feet is orderly, stable, and trustworthy.
You need LOW trust for risk taking.
I think in practice the conditions that lead to high trust societies forming also tend to lead to culturally valuing predictability which translates to a bias against risk. But that's not an inherent part of high trust rather that's just how things happen to be at a given point in time.
