["Journal of Social Philosophy, EarlyView. ", "\nABSTRACT\nWe develop a comprehensive account of self‐trust in its role‐mediated, general and universal forms, highlight the connection between self‐trust and personal autonomy, and argue that we can have too much or too little self‐trust. Both can undermine personal autonomy. Our account explicates and supports three compelling theses about trust: that interpersonal trust is often trust in a person in a social role (Thesis One); that self‐trust is a nonprototypical variant of interpersonal trust (Thesis Two); and that self‐trust is essential to autonomy (Thesis Three).\n"]
