Gladwell does not cultivate gravitas and doesn’t much mind if you disagree with him. He is an intellectual hedonist: his big idea is that ideas should be pleasurable. Rather than trying to persuade, he seeks to infect readers with his enthusiasms: isn’t this interesting? This ethos has birthed a whole publishing industry. It’s only a slight exaggeration to say that, without Gladwell, there would no Freakonomics, no Nudge, no TED Talks, no “Smart Thinking” section in Waterstones. For those who find the whole genre unbearably superficial, Gladwell is to blame.
