Still, posture has become a boogeyman in the popular culture—and that's unlikely to go away anytime soon. "People, in general, over-assign posture as the source of their medical conditions," Robertson told PopSci in 2018. Some doctors, for example, attribute a condition called trigger finger, where an appendage gets stuck in a bent position, to the way some patients balance their phones on their pinkies. But Robertson says researchers are increasingly cognizant of the way countless other factors contribute to postural issues, many of them invisible. When it comes to trigger fingers, bone spurs, or even carpal tunnel syndrome, we now realize that genetics, overall fitness, individual behavior between various positions, general strength, immune response, and even nutrition can play a role.
