Yeah no people are too dumb to do that. Unless you're in some monoculture society, it's almost impossible to get trust consensus.

For example people like to see accreditation or regulation or certified organic or whatever and they also 'trust' the 'institutions' and choose products that have these certifications.

For example, people won't download apps that's not from the Google Play store. If you just host the APK. People don't trust like that..
