Assistant Professor

Campus:

UTSC,

Biography:

  • PhD, University of Maryland
  • BA, University of Minnesota

Christian Tarsney works mostly in ethics, with a focus on ethically motivated decision-making under conditions of uncertainty. He is interested in questions like how much weight we should give to tiny probabilities of extremely good or bad outcomes, how to deal with uncertainty about basic moral principles, and how to make choices that affect (or might affect) the size of the future population. He also recently started thinking about philosophical questions related to artificial intelligence, like what it means for an AI system to be “deceptive” and whether there is a natural tendency for AI agents to engage in power-seeking behavior. Finally, he has a side interest in philosophy of time, particularly in the “bias toward the future” — our strong but strangely hard-to-justify preference that pleasant experiences be in the future rather than the past, and unpleasant experiences in the past rather than the future.

Dr. Tarsney earned his PhD at the University of Maryland, and before coming to U of T, held research positions at the University of Groningen’s Centre for Philosophy, Politics and Economics, Oxford’s Global Priorities Institute, and UT Austin’s Population Wellbeing Initiative.
