    This makes a lot of sense. Human brain is expensive in terms of energy, so it is useful to cache computation (moral or otherwise). Downside is that when the cache is corrupted, you get the wrong result.

      The brain’s energy consumption is pretty flat regardless of mental state (review paper)

      What our decisions do affect is how much energy/time we expend executing them and also deciding on actions. So stereotypes and other statistical short cuts we take are mostly to save time deciding so we can act quickly and not miss the moment.

      Nature is working on becoming magic err I mean illusion magazine?

        No. Illusion/trickery/magic is the means in this experiment, not the goal. The result of the experiment is articulated in the last paragraph:

        “These findings suggest that if I’m fooled into thinking that I endorse a view, I’ll do the work myself to come up with my own reasons [for endorsing it],”

          People can be tricked into reversing their opinions on moral issues, even to the point of constructing good arguments to support the opposite of their original positions, researchers report today in PLoS ONE

          Actual article is here: “Lifting the Veil of Morality: Choice Blindness and Attitude Reversals on a Self-Transforming Survey”

          I wonder about the longevity of the effect. There are a lot of things that can be done with “behaviorist” techniques like this that are surprisingly effective for short periods of time. Research into curing fear of flying, for example, abounds with cases of people who are seemingly trained out of it by sitting in an airplane seat, talking through takeoff and landing and other stages of flight – but then relapse within a few months.
