The [Just Mathematics Collective](https://justmathematicscollective.net) maintains a [list of resources](https://justmathematicscollective.net/resources.html) related to ethics in mathematics.

One of those resources is itself a list of resources, an [Ethics in Mathematics reading list](https://docs.google.com/document/d/1P4xAUa9qfEbeCjurGOdJH3dW2JErVRJZ1K9DLAT8uYE/edit) by Allison N Miller. This reading list alone is 12 pages long - food for thought for those who think there's nothing to say here.
