I point this out to help locate what your heuristic is really approximating[1]. I.e., two components of something like memetic fitness: (1) a reason to care, (2) low entanglement with other beliefs.
By the term “reason to care” do you mean that the claim is relevant to someone’s interests/goals?
eg, a claim of the form “X is healthy” is probably relevant for someone who highly values not dying
eg, a claim of the form “Guillermo del Toro’s new movie is on Netflix.” is probably not relevant for someone who does not value watching horror films
