The crucial question, at least to her, is whether (and when) we want to use the tools of decision science to try and steer people toward better choices. If our preferences aren’t fixed the way we think they are — if, as Weber has argued, they’re sometimes merely constructed on the spot in response to a choice we face — why not try new methods (ordering options, choosing strategic words, creating group effects and so forth) to elicit preferences aligned with our long-term interest? That has to be better, in Weber’s opinion, than having people blunder unconsciously into an environmental catastrophe.
