One of the key abstract memetic components of LW is something along the lines of "use recent research findings about cognition from fields like psychology, artificial intelligence, probability, and economics to improve your own thinking." That seems like an idea worth spreading. People could use that idea even if they didn't accept or understand specific individual techniques like value-of-information calculations.
On the other hand keep in mind that many research findings in medicine (and especially psychology) fail to replicate.
My favorite is that people get credit for updating based on evidence.
The more common reaction is for people to get criticized (by themselves and others) for not having known the truth sooner.
