MoralFoundations.org is an educational website run by the YourMorals.org collaboration, offering information and resources on Moral Foundations Theory (MFT). Developed by social and cultural psychologists, including Jonathan Haidt and Jesse Graham, the theory examines the psychological systems that shape moral intuitions across cultures. It describes how societies build virtues, narratives, and institutions on shared foundations, while recognizing that moral beliefs vary and can conflict. The site explains the theory’s development, research, and applications, including its distinction between descriptive accounts of morality and claims about what is morally good.

Visitors can explore materials on the foundations of care, equality, proportionality, loyalty, authority, and purity, along with possible additional foundations such as liberty, honor, and ownership. The website provides academic publications, videos and press coverage, questionnaires, and other learning materials, as well as links to further resources. It also recommends accessible and scholarly introductions to MFT, including books, chapters, and research papers, and presents videos about the theory’s relevance to American politics.
