Warren Buffett appears to have done for "negative feedback" what Alanis Morisette did for irony:
The U.S.—and much of the world—became trapped in a vicious negative-feedback cycle. Fear led to business contraction, and that in turn led to even greater fear.That is a description of a positive-feedback cycle, not a negative-feedback cycle.
Buffett's "slip" is eerily reminiscent of George Costanza's "on the wagon" mind-fake:
Jerry: Yeah. He's been off the wagon for two years.
George: "Off the wagon"?
Jerry: I think it's off the wagon.
George: I think it's "on the wagon".That was actually Jerry Seinfeld's my "off the wagon" mind-fake.
