>> Positive emotion is not correlated with truth.

I assumed from your previous comment(below) that you are correlating negative emotion with misinformation and disinformation. If that's not what you meant, then I guess I misunderstood what you meant by your previous comment

>> Facebook has designed its algorithms for spreading misinformation and disinformation, because emotion drives engagement

The easiest negative emotion to cause with a post is outrage, which goes nicely with fake news.

The easiest positive emotion to cause are at the result of puppies and wholesome/faith-in-humanity-restored posts, neither are generally related to actual truthful news.

I don’t see how that assumption is implied by anything I said in what you quoted. There is no reference to the valence of the emotion.
