Our Moral Parliament Tool allows users to navigate uncertainty about key assumptions that affect our assessment of interventions. It does so by representing diverse perspectives as delegates in a democratic decision-making process about how to distribute resources.

We have added functionality to the original Parliament Tool, which allows it to be adapted to novel resource allocation problems simply by editing a spreadsheet.

We have built four ready-to-use parliaments that demonstrate the versatility and utility of the tool:

• GiveWell Parliament: Evaluate global health charities using different moral weights, including animal welfare considerations that GiveWell does not currently include [post /​ parliament]

• Animal Parliament: Set funding priorities across different kinds of farmed animals (chickens, fish, shrimp, and insects) given uncertainty about sentience, welfare ranges, and project success rates [post /​ parliament]

• Bioethics Parliament: Allocate healthcare resources in light of diverse bioethical views (e.g., Rule of Rescue, Utilitarian, etc.). [post /​ parliament]

• Movement Building Parliament: navigate strategic decisions about growing effective altruism (though this is more speculative and serves primarily as a template for users to modify) [post /​ parliament]

We also provide instructions for how users can adapt the Parliament for their own resource allocation problems.
