So how do _you_ make any sort of judgments based off of what people say? What information do you use to judge whether their statements are accurate? Or do you always start with the assumption that everything everyone says is suspect? What sort of information do you use to come to any sort of conclusion, and how do you determine the trustworthiness of that information?

>This is domain authority again - trust some domains manually, let it flow from there. If that domain trusts another domain then they link to it, trust flows to the other domain, and so on. Maintaining such trust for a long time adds to a particular domains trust factor, linking to domains not trusted by others detracts from it.

This can be gamed if you're able to update the trustworthiness of a domain for other people, and that's why a trust metric needs to be mostly personal, and should update dynamically based on your changing trust valuations.
