I disagree.

Suppose you had a firm belief about something, and I sought to change that. So I told you something about myself which challenged your belief on the subject. Inspired by my personal story, you began to see the subject from a different perspective. Now suppose the story I told you was a lie, and I deceived you with the sole intention of getting you to reevaluate your beliefs. Of course, ideally, you would never find out about my deception. Nonetheless, I got you to think differently about something because of a lie.

When I was younger and more reckless, I used to play this game where I would attempt to Trojan Horse ideas into a community that would normally scoff at the mere mention of such ideas were someone to present them in good faith. For example, I would join a group of misogynists with the intention of undoing their misogyny. I would craft personas around this deception, first playing along with them, and then, little by little, challenging their beliefs.

It was a fun exercise. Learned a lot about people.
