Maybe it's not necessary to define truth for this. Considering metrics that you want to influence might be a better way - hate crime arrests in locales, negative/divisive message content, donations/volunteering for positive causes, etc. But I'm a pessimist and I think moving these metrics in the right direction would adversely affect the $$$ metric that shareholders care about, so it's not going to happen.
