“Yet getting people to use simple language isn’t always easy. Smart talkers have considerable incentive for saying things that are incomprehensible. Unfortunately, people who spew out incomprehensible ‘jargon monoxide’* are rated as smarter than those who use simple words – especially when they are renowned for their expertise. This attribution even occurs when people use unintelligible language to mask meaningless and useless ideas. So beware that when people seem so smart that you can’t understand a word they say, these pretenders may have learned that blasting out jargon monoxide is the best way to get ahead and mask their incompetence at the same time. Authentic experts have no incompetence to mask but must beware of ‘the curse of knowledge’: The more people know about something, the harder it is for them to package explanations and instructions in ways that others can comprehend. Stanford’s Pamela Hinds, for example, showed that people with the greatest expertise at operating a cell phone did the worst job of teaching novices to operate the phone. This curse happens because experts have a hard time putting themselves in the shoes of neophytes. Experts’ actions become so automatic to them that they forget the simple steps they had to learn and other struggles they faced as novices.”
