Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale
NSF has posted an “update on priorities.”

They’re canceling all “DEI and misinformation/disinformation” grants.

And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent.
