NEW YORK - Katie Couric says her move to CBS would have been less appealing if she had known she'd be doing the more traditional "CBS Evening News" broadcast that she anchors now.

"People are very unforgiving and very resistant to change," Couric said in an interview with New York magazine. "The biggest mistake we made is we tried new things."

Couric's move to CBS has been a bust so far. The evening newscast's ratings are deep in third place, and CBS has rolled back some of the changes it made last fall to shake up the format. Couric conducts fewer interviews, an outside opinion segment was scrapped and the anchor admits she's even dressing down a little to give her critics less ammunition.

Under new executive producer Rick Kaplan, the "CBS Evening News" is a more traditional hard-news evening newscast in the mould of its predecessors and competitors.

If she had known that would happen, the job "would have been less appealing to me. It would have required a lot more thought."

A thriftier corporate culture at CBS and colleagues who back-bite anonymously in the media surprised her, she said. She also said she under-estimated the feeling that people would not consider herself a credible news person because of her work on NBC's "Today" show, even though she thinks it's "patently unfair."

She said she's looking forward to doing more work for "60 Minutes" next season. "If it turns out it wasn't a perfect fit (at the evening news), then, you know, I'll do something else that's really exciting and fulfilling for me."

Couric admitted there are days when she wishes she hadn't made the move to CBS.

"Of course," she said. "I'm human. I'm not going around 'dee-da dee-da dee.' I have days when I'm like, 'Oh my God, what did I do?' But for some weird reason, they don't happen that often."
