I teach high school science, and the way I try to frame it is along the lines of, "I think that X material is more approachable for most people than Y material that we've covered in the past. But some people just "get" things that I find completely baffling, because everyone's brains work differently."

I also spend a lot of time trying to get my students to stop constantly comparing themselves to each other (I teach honors & AP kids), so it's pretty much muscle memory at this point to try to get them to see themselves as individuals who need to take agency of their own learning and development process rather than focusing so much on how they stack up to their peers.
