Think about Belle from Beauty and the Beast. She is a smart, ambitious, independent young woman who trades her freedom for her father’s and over time comes to love the inconsiderate, dominating Beast who keeps her captive.
On one plausible reading, Belle’s case is a classic case of adaptive preference. By adaptive preference, I mean a preference that a person forms for an option in a limited set, that she would not have formed if other more expansive options had been available. And such preferences tend to raise problems for social and political philosophers and well-being theorists because they pull us simultaneously in two different directions: because they are the person’s own preferences, it seems that they are relevant to – perhaps even decisive in – determining what is good for her or how she should be treated; but because they involve settling for what she can get rather than a desire for what she would want if only it were available, they do not seem to capture what is genuinely good for her.
