It’s not surprising to me, though I imagine it’s vulnerable to massive selection effect. My observation is about people who actually internalized being a non-smoker, not those who tried to do so and failed. I’m not surprised those two things are extremely highly correlated. So it might not be any better as strategy advice than “the best way to quit smoking is to successfully quit smoking”.
