“In 2005, researchers at the University of Southern California found the first evidence of brain abnormalities in pathological liars — the prefrontal cortex is always very active when people are telling lies, but their study found that liars had 25 percent more white matter, and 14 percent less gray matter, in their prefrontal cortex than non-liars, suggesting there can be a physiological predisposition to being a bullshit artist.”
“So bullshitting isn’t just nonsense. It’s constructed in order to appear meaningful, though on closer examination, it isn’t. And bullshit isn’t the same as lying. A liar knows the truth but makes statements deliberately intended to sell people on falsehoods. bullshitters, in contrast, aren’t concerned about what’s true or not, so much as they’re trying to appear as if they know what they’re talking about. In that sense, bullshitting can be thought of as a verbal demonstration of the Dunning-Kruger effect—when people speak from a position of disproportionate confidence about their knowledge relative to what little they actually know, bullshit is often the result.”
