I am a (lapsing) mindful meditator, and I'm still not sure this article contradicts any of that stuff (which is the distilled science from things like Buddhism.)
Quite possibly its arrogance, or jadedness. But I've come to develop my own opinions about issues like that, through other means of acquiring knowledge than science, which I feel is grossly inadequate to address such issues. And no, I'm not talking about secular/clinic types of mindfulness.
Probably that makes me a weirdo in circles like HN, but oh well.
