Harvard Business School professor Clayton Christensen’s ideas about why some businesses adjust to competition and some don’t were so controversial that a battle broke out on Twitter within hours of his death last Friday at the age of 67.
Christensen’s best-known critic by far, though, was Harvard historian Jill Lepore. Nearly six years ago, in a long essay for The New Yorker, Lepore lambasted Christensen’s theories as flights of fancy with little evidence to back them up.
I had read Christensen’s first book about disruption theory, “The Innovator’s Dilemma,” and thought he had some provocative things to say about the struggling news business. So not long after Lepore’s piece appeared, I wrote a self-published essay for Medium about Lepore and Christensen’s battle of ideas, which I’m republishing here this week.
Obviously the world doesn’t look exactly the same in 2020 as it did in 2014. But if you’re wondering who Clay Christensen was and what disruption theory is all about, I hope you’ll find that this is a useful introduction.
