Affirming the Scientific Consensus on Bias and Discrimination in AI

We, the undersigned researchers, affirm the scientific consensus that artificial intelligence (AI) can exacerbate bias and discrimination in society, and that governments need to enact appropriate guardrails and governance in order to identify and mitigate these harms. [1]

Over the past decade, thousands of scientific studies have shown how biased AI systems can violate civil and human rights, even if their users and creators are well-intentioned. [2] When AI systems perpetuate discrimination, their errors make our societies less just and fair. Researchers have observed this same pattern across many fields, including computer science, the social sciences, law, and the humanities. Yet while scientists agree on the common problem of bias in AI, the solutions to this problem are an area of ongoing research, innovation, and policy.

These facts have been a basis for bipartisan and global policymaking for nearly a decade. [3] We urge policymakers to continue to develop public policy that is rooted in and builds on this scientific consensus, rather than discarding the bipartisan and global progress made thus far.

[3] In 2016, the Obama White House published a report that noted how AI can exacerbate bias. In 2019, the Trump Administration endorsed the OECD Recommendation on AI, an agreement adopted by 42 countries which identified non-discrimination, equality, diversity, and fairness as values for AI development. In 2020, the Trump White House established fairness and non-discrimination as a principle for regulating AI, and President Trump signed an executive order that directed the federal government to use AI in a manner that protects civil rights. In 2021, a bipartisan law directed the Office of Management and Budget to issue guidance on mitigating discriminatory impacts and bias in federal use of AI. In 2022, the Biden White House issued the Blueprint for an AI Bill of Rights, which identified civil rights as a core priority for AI governance, and in 2023, President Biden issued multiple executive orders that directed agencies to root out bias in AI and the National Institute of Standards and Technology issued a Risk Management Framework that stated trustworthy AI is fair with harmful bias managed. In 2024, the Bipartisan House Task Force Report on AI stated that “one major set of risks caused by improper design and use of AI systems is harmful bias.” Also in 2024, all 193 members of the United Nations adopted a resolution calling on members to “avoid reinforcing or perpetuating discriminatory or biased applications and outcomes throughout the life cycle of AI systems,” and the United Nations, in its Global Digital Compact, called for action to ensure equitable deployment of AI systems that avoid harms of bias of discrimination in all aspects of governance. In 2025, the first International AI Safety Report, with contributions from 96 AI experts, highlighted the harms from bias due to malfunctioning of AI systems, and described ongoing research on risk mitigation.
