Project: Safety Constraints and Ethical Principles in Collective Decision Making Systems

Amount Recommended:    $275,000

Project Summary

The future will see autonomous machines acting in the same environment as humans, in areas as diverse as driving, assistive technology, and health care. Think of self-driving cars, companion robots, and medical diagnosis support systems. We also believe that humans and machines will often need to work together and agree on common decisions. Thus hybrid collective decision making systems will be in great need.

In this scenario, both machines and collective decision making systems should follow some form of moral values and ethical principles (appropriate to where they will act but always aligned to humans’), as well as safety constraints. In fact, humans would accept and trust more machines that behave as ethically as other humans in the same environment. Also, these principles would make it easier for machines to determine their actions and explain their behavior in terms understandable by humans. Moreover, often machines and humans will need to make decisions together, either through consensus or by reaching a compromise. This would be facilitated by shared moral values and ethical principles.

We will study the embedding and learning of safety constraints, moral values, and ethical principles in collective decision making systems for societies of machines and humans.

Technical Abstract

The future will see autonomous agents acting in the same environment as humans, in areas as diverse as driving, assistive technology, and health care. In this scenario, collective decision making will be the norm. We will study the embedding of safety constraints, moral values, and ethical principles in agents, within the context of hybrid human/agents collective decision making. We will do that by adapting current logic-based modelling and reasoning frameworks, such as soft constraints, CP-nets, and constraint-based scheduling under uncertainty. For ethical principles, we will use constraints specifying the basic ethical “laws”, plus sophisticated prioritised and possibly context-dependent constraints over possible actions, equipped with a conflict resolution engine. To avoid reckless behavior in the face of uncertainty, we will bound the risk of violating these ethical laws. We will also replace preference aggregation with an appropriately developed constraint/value/ethics/preference fusion, an operation designed to ensure that agents’ preferences are consistent with the system’s safety constraints, the agents’ moral values, and the ethical principles of both individual agents and the collective decision making system. We will also develop approaches to learn ethical principles for artificial intelligent agents, as well as predict possible ethical violations.

    • This article highlights (a) the poor incentives for transparency faced by AV manufacturers, (b) shifts in thinking that may occur as AVs go from sets of uncoordinated individual vehicles to coordinated AV systems, and (c) the shortcomings in contemporary ethical theory and commonsense moral intuition that must be overcome to imbue AVs and other autonomous systems with satisfactory ethical guidance.

  1. Colloquium Series on Robust and Beneficial AI (CSRBAI): May 27-June 17. MIRI, Berkeley, CA.
    • Rossi participated in this 22-day June colloquium series ( with the Future of Humanity Institute, which included four additional workshops.
    • Specific Workshop: “Transparency.” May 28-29.
      • In many cases, it can be prohibitively difficult for humans to understand AI systems’ internal states and reasoning. This makes it more difficult to anticipate such systems’ behavior and correct errors. On the other hand, there have been striking advances in communicating the internals of some machine learning systems, and in formally verifying certain features of algorithms. These researchers would like to see how far they can push the transparency of AI systems while maintaining their capabilities.
