The website and title here state the goal is to fight misinformation. In this post you state the goal is to show we have reasons to be optimistic about the world.

Which is it?

I'm not super convinced that the framing of the questions does provide reasons to be optimistic. Instead it comes across to me as a down-playing of issues of serious concern.

What is the evidence that your approach does increase optimism, and what is the evidence that such optimism is warranted?

Have you tried the alternate framing as suggested in above posts, perhaps A/B testing? This might give the lie to your assertion that people are "systematically" incorrect, which frankly I feel to be an overstatement.

Unfortunately I have the distinct feeling of wool being pulled over my eyes.
