The singer insisted that the show doesn't produce good music and questioned the validity of the programme's experts such as Louis Walsh.
Cocker told Shortlist: "I gave up on The X Factor when they did that awful version of 'Heroes' by David Bowie. It's not music, is it?
"I don't want to sound like a fuddy-duddy, but to me it's everything I don't agree with.
"The thing that makes good music is the idea that somebody stumbles upon something or just through their enthusiasm and energy they invent something by accident."
He continued: "That's where great music has come from. Probably all great art, if we're honest.
"And the idea on The X Factor that these experts come in and tell you how to do it, how to style yourself and everything else.
"Also look at the level of these experts. In a world where Louis Walsh can be considered an expert, something's wrong. I hate that because it makes kids think that there's a proper way to be a popstar, like there's a formula. And it's crap."
Cocker recently hinted that Pulp may announce a new UK tour soon during a gig at the Royal Albert Hall.
