I'd submit that this is not adequate, because it allows for too much bias towards that which you already believe to be true; and to too-easily reject that which does not already fit in with your preconceptions. Actively falsifying claims you already believe is pretty key. Doing that on your own is essential. It's difficult, especially if you're embedded within a social context that believes "the other side" is stupid at best.
