Preferência Revelada x Felicidade

Will Wilkinson writes,
The neuroscience shows that satisfaction of the highest ranked preference does not imply the greatest hedonic satisfaction. It does not imply any hedonic satisfaction. Take a look at this paper, “Parsing Reward,” [pdf] by Kent Berridge and Terry Robinson. They report that “wanting” and “liking” have “are in fact dissociable and have different neural substrates.” Roughly, the dopamine system is more about wanting–”incentive salience”–and liking or hedonic satisfaction has more to do with opioids.

Roughly speaking, economics shows how resources can be used most efficiently to satisfy wants. It does not connect satisfying wants with hedonic satisfaction, or happiness.
