From your link: frequent left-right confusion. It appears, however, to be linked to brain lateralization — the idea that the right and left halves of the brain’s cerebral cortex control different functions. ... “In 2009, British scientists found that those whose hearing was more biased toward one ear over another, a sign of asymmetry, were more likely to display confusion.”
well, that explains it. I also have a slight midrange hearing loss in right ear. Or is it the left? LOL
