Experts perform a valuable function in our modern world.
Whenever we get into an argument, whether heated or as a diversion, it isn't long before we reach for a forceful quote or two from an expert. Experts strengthen our confidence in views we've chosen to defend. Experts supposedly know what they're talking about because they've got the inside track on specialized knowledge. Experts are called upon to give us the final word in matters both obscure and self-evident. And sometimes experts are wrong.
