It's the only way, and it usually doesn't work.

Lies win, because reality is fighting with one hand tied behind its back. Truth is nearly always boring because it's forced to be consistent. Lies have no such limitations.

Truth does have the advantage that it appeals to people who aren't complete dumbfucks. Which is to say, a tiny minority.

The average person is much more susceptible to lies that seem evident than truths that are difficult. By proxy, it seems you're also making a statement on the intelligence of the average individual?

Things like truth and lies aren't constants. Generalizing how they come into existence is a self-fulfilling story.

The past decade of social media has proven that that isn't how the world works in practice. Lies fly all round the world before the truth even gets out of bed.

There's nothing wrong with incorporating how someone is likely to use information when determining which information to share with them. I'm no Kantian.
