I am not sure that trustworthiness has increased marginal utility. Think about ebay or Amazon, what is the difference between 99% positive and 100% positive. Or 97% positive or 100% positive. It would seem to me that with trustworthiness there is a tipping point, at which there is a huge spike in marginal utility, and all other increases don’t really add much utility.
100% positive on Amazon isn’t the same as the 100% trust mean. 100% on amazon really is just a bit higher the 99%. 100% trust can’t be expressed by Amazon ratings as the the underlying rating can still be hacked or ‘optimized’.

Agreed. The mapping from Amazon ratings to actual trustworthiness is pretty nonlinear.
Nonlinearity alone wouldn’t be a problem. The problem is that the mapping isn’t injective.
