Dr Iason Gabriel
Philosopher & Research Scientist at Google DeepMind
My work focuses on the ethics of artificial intelligence, including questions about AI value alignment, distributive justice, language ethics and human rights.
More generally, I’m interested in AI and human values, and in ensuring that technology works well for the benefit of all. I’ve contributed to several projects that promote responsible innovation in AI.
Before joining DeepMind, I taught moral and political philosophy at Oxford University and worked for the United Nations Development Programme in Lebanon and Sudan.

Summary
Proposes a framework for characterising AI agents along four dimensions – autonomy, efficacy, goal complexity and generality – and uses it to build ‘agentic profiles’ for different kinds of agent, from narrow task-specific assistants to highly autonomous general-purpose systems, as guidance for effective AI governance.
- 2025We need a new ethics for a world of AI agents
Summary
As capable AI agents begin to act in the world on people’s behalf, they raise fresh questions about safety, about human–machine relationships and about social coordination – questions that call for a new ethics of AI agents.
- 2025Why human–AI relationships need socioaffective alignment
Summary
As AI becomes more personalised and agentic, people are forming deeper and more persistent relationships with it. Introduces ‘socioaffective alignment’ – how an AI system behaves within the social and psychological ecosystem it co-creates with its user – and argues for AI that supports, rather than exploits, our nature as social and emotional beings.
- 2025A matter of principle? AI alignment as the fair treatment of claims
Summary
Existing answers to the question of what AI should be aligned with – human intentions, or being helpful, honest and harmless – are incomplete and justified in the wrong way. Proposes instead that AI should be aligned with principles that are the product of fair processes, meeting the standard of public justification owed to people in pluralistic societies.
- 2024The Ethics of Advanced AI Assistants
Summary
A comprehensive study of the opportunities and the ethical and societal risks posed by advanced AI assistants – agents that plan and act on a user’s behalf. Covers value alignment, well-being, safety, manipulation, anthropomorphism, trust and privacy, and societal-scale effects, and closes with recommendations for researchers, developers, policymakers and the public.
- 2023Using the Veil of Ignorance to align AI systems with principles of justice
Summary
Applies John Rawls’s Veil of Ignorance to the governance of AI. Across five studies with over 2,500 participants, people choosing principles for an AI assistant from behind the veil consistently preferred a principle that prioritises the worst-off – a choice driven by concerns about fairness rather than risk attitudes or politics.
- 2023In Conversation with Artificial Intelligence: Aligning Language Models with Human Values
Summary
What does it mean to align conversational agents with human norms and values? Develops a philosophical analysis of linguistic communication between people and conversational agents, identifies ideal norms of conversation, and shows how these norms can guide alignment across different discursive domains.
- 2022Toward a Theory of Justice for Artificial Intelligence
Summary
Drawing on John Rawls, argues that the basic structure of society is increasingly shaped by AI, so egalitarian norms of justice apply to the technology. AI systems must meet a standard of public justification, support citizens’ rights and promote substantively fair outcomes, with particular attention to the worst-off.
- 2021Ethical and social risks of harm from language models
Summary
Maps the landscape of risks associated with large language models across six areas: discrimination and toxicity, information hazards, misinformation, malicious uses, human–computer interaction harms, and automation, access and environmental harms.
- 2020Artificial Intelligence, Values, and Alignment
Summary
Defends three propositions: the normative and technical sides of AI alignment are interrelated; it matters whether AI is aligned with instructions, intentions, preferences, interests or values; and the central challenge is not to find ‘true’ moral principles for AI, but fair principles that can win reflective endorsement despite widespread moral disagreement.
- 2017Effective altruism and its critics
Summary
Examines the main objections to effective altruism – that it neglects justice, equality, urgency and rights, that it suffers from methodological bias, and that it struggles to achieve systemic change – and weighs the force of each, along with possible responses.
