How to Build Ethics into Robust Artificial Intelligence (2017-2018)

The goal of this project was to combine computational methods, philosophy, game theory and psychology to develop robust and ethical moral artificial intelligence (“moral AI”) to direct autonomous agents.

The project team’s research address several of the main challenges in designing moral AI through three subprojects.

  1. The team used in-person experiments and online platforms such as Amazon Mechanical Turk (MTurk) to ask people what types of factors they believe kidney exchange algorithms should and should not take into account. Team members built a website for large-scale data collection for online participants, analyzed participants’ responses to find common ethical themes and then revised current kidney exchange algorithms so that their recommendations of how kidneys should be allocated will take these ethical themes into account. This “bottom-up” approach relied primarily on new data to learn the moral features that should be incorporated into AI algorithms.
  2. The team also combined principles from moral philosophy and economic game theory to design scenarios and games that asked participants to judge the actions described or displayed in specific moral situations. Team members began by focusing on the “trust game” and had MTurk participants play the trust game against one another and then report how morally wrong or acceptable they thought their actions and their partner’s actions were. Team members collected data, began analysis on performance and used participants’ morality ratings to refine game theoretic notions so that they account for behavior in the trust game more accurately. This “top-down” approach relied primarily on game theory and ethical theory to generate algorithms that can make ethical choices.
  3. Team members also asked participants whether they thought humans or computers should be making decisions in a wide range of scenarios and applications.
