Not direct revelation? Works okay between two people. Unless you do controlled blind study on everything you observe and hear.

The only truth I think you could confirm is that you believe you got information X from person Y. You couldn't have a high degree of confidence that X is 'true' in any meaningful sense just from the revelation.

According to your view, I can't have confidence that your statement is "true" in any meaningful sense. But in my view, I can (though I don't, because it's "false").
