In short, gamers think they are an inverter or a non-inverter because of how they were first exposed to game controls. Someone who played a lot of flight sims in the 1980s may have unconsciously taught themselves to invert and now they consider that their innate preference; alternatively a gamer who grew up in the 2000s, when non-inverted controls became prevalent may think they are naturally a non-inverter. However, cognitive tests suggest otherwise. It’s much more likely that you invert or don’t invert due to how your brain perceives objects in 3D space.
