I’m a journalism professor and science journalist, and though I’ve written for Wired once or twice (and I happen to know and like Wired’s editor, Chris Anderson), I was a relatively neutral, outside party who could check Lehrer’s blog for journalistic malfeasance. So Wired.com asked me to take a look.

My task was not to decide whether Lehrer got everything right—every journalist makes mistakes and misinterprets things—but to determine whether he recycled, fabricated, plagiarized, or otherwise breached journalistic ethics.

I soon came to the conclusion that he had.
