Experiments on choice blindness support von Hippel & Trivers's (VH&T's) conception of the mind as fundamentally divided, but they also highlight a problem for VH&T's idea of non-conscious self-deception: If I try to trick you into believing that I have a certain preference, and the best way is to also trick myself, I might actually end up having that preference, at all levels of processing.

There are two kinds of epistemic theories about self-knowledge: the traditional account, and the inferentialist account. According to the traditional view of self-knowledge, we have privileged access to our propositional attitudes. “Privileged access” means that one can gain knowledge of one’s own propositional attitudes directly via an exclusive, first-personal method called introspection. On the other hand, the inferentialist view of self-knowledge postulates that we don’t have privileged access to our propositional attitudes and must infer or self-attribute them instead. In this (...) thesis I argue that the traditional view of self-knowledge, which postulates that we have privileged access to our propositional attitudes, ought to be abandoned in favor of an infernetialist picture of self-knowledge I argue that recent experimental results in social psychology strongly imply that we don’t have privileged access to our propositional attitudes. In the choice blindness paradigm, the majority of participants can be manipulated into becoming oblivious to choices that they made just moments previously. Not only do participants utterly fail to notice that they did not receive what they wanted, but they also provide confabulated reasons as to why they made their “decision.” I maintain that the phenomena of choice blindness and confabulation are very difficult for the traditional theory of self- knowledge to accommodate and explain; whereas, on the other hand, the inferentialist account actually predicts and anticipates these experimental findings. The traditional theorist cannot avoid the threat that choice blindness and confabulation pose by restricting the scope of privileged access even further, to exclude propositional attitudes, because privileged access to propositional attitudes is the very property which distinguishes the traditional view of self-knowledge from an inferentialist account. The traditional theorist might attempt to argue that privileged access to propositional attitudes is conceptually necessary, but I maintain that this argument fails. The traditional theorist’s only option, then, is to adopt a dual-method account whereby we sometimes gain self-knowledge via introspection and sometimes via inference. However, I maintain that the dual-method approach is a much weaker theory in terms of explanatory power when compared to the inferentialist account. On balance, then, the traditional view of self-knowledge should be rejected in favor of the inferentialist account. (shrink)

When subject to the choice-blindness effect, an agent gives reasons for making choice B, moments after making the alternative choice A. Choice blindness has been studied in a variety of contexts, from consumer choice and aesthetic judgement to moral and political attitudes. The pervasiveness and robustness of the effect is regarded as powerful evidence of self-ignorance. Here we compare two interpretations of choice blindness. On the choice error interpretation, when the agent gives reasons she is in fact wrong about what (...) her choice is. On the choice change interpretation, when the agent gives reasons she is right about what her choice is, but she does not realise that her choice has changed. In this paper, we spell out the implications of the two interpretations of the choice-blindness effect for self-ignorance claims and offer some reasons to prefer choice change to choice error.
