In David Burn's book "Feeling Good", a CBT self-help book, he teaches how to identify 10 cognitive distortions in our thinking patterns and develops practices for counteracting them.
Among the distortions he identifies are all-or-nothing-thinking (i.e. splitting). I don't remember if he says anything about projection specifically, but another of the distortions is mind-reading/jumping-to-conclusions, which at least is in ballpark of falsely attributing mental states to others.
The context of the book is to alleviate your own depression, but it is also really interesting from an anti-biasing perspective.
