Chek out Maya Mathur’s slides on the state of nudging research: https://osf.io/encd5

I also wrote a recent meta-analysis of MAP reduction research that identifies some high-quality RCTs as well as collates some prior systematic reviews: https://forum.effectivealtruism.org/posts/k9qqGZtmWz3x4yaaA/environmental-and-health-appeals-are-the-most-effective

From a moral philosophy/psychology perspective, check out Lucius Caviola at Harvard or Eric Schwitzgebel : http://www.faculty.ucr.edu/~eschwitz/

These aren’t exactly syllabi, but I think that between these researchers you’ll be able to put something nice together.

I would be obliged to see the final product when you have one!
