There is an apparent tension in current accounts of the relationship between reason giving and self knowledge. On the one hand, philosophers like Richard Moran (2001) claim that deliberation and justification can give rise to first-person authority over the attitudes that subjects form or defend on the basis of what they take to be their best reasons. On the other hand, the psychological evidence on the introspection effects and the literature on elusive reasons suggest that engaging in explicit deliberation or justification leads subjects to report attitudes that are not consistent with their previous attitudes or with their future behavior. On the basis of these findings, Tim Wilson (2002) argues that analyzing reasons compromises self knowledge. I shall defend a realistic account of the effects of reason giving which is compatible with the empirical findings on introspection and also with the claim that deliberation and justification have epistemic benefits.

The right not to know is often defended on the basis of the principle of respect for personal autonomy. If I choose not to acquire personal information that impacts on my future prospects, such a choice should be respected, because I should be able to decide whether to access information about myself and how to use it. But, according to the incoherence objection to the right not to know in the context of genetic testing, the choice not to acquire genetic information undermines the capacity for autonomous decision making. The claim is that it is incoherent to defend a choice that is inimical to autonomy by appealing to autonomy. In this paper, I suggest that the choice not to know in the context of genetic testing does not undermine self-authorship, which is a key aspect of autonomous decision making. In the light of this, the incoherence objection to the right not to know seems less compelling.
