Everyone from Health staffers (full disclosure: I’m a Laurel) to Chrissy Teigen and Mindy Kaling can't appear to agree, so we felt it was time to name in an professional. Don Vaughn, PhD, a neuroscientist and musician, helps us make a sound judgment on the matter.
“It’s a actually attention-grabbing phenomenon,” he tells Health. The mind tries its finest to create "one unified mannequin of the world," he says–however on the finish of the day, one individual's particular person mind is only one particular person interpretation, he explains.
