 While a relatively small percentage of empirical work on “heuristics and biases” directly addresses moral reasoning, numerous philosophers who have addressed the issue (Horowitz 1998; Doris &amp; Stich 2005; Sinnott-Armstrong 2005; Sunstein 2005) agree that phenomena like framing effects are likely to be pervasively implicated in responses to ethically freighted examples, and argue that this state of affairs should cause philosophers to view the thought-experimental method with considerable concern.
