We are capable of evaluating not only the content of a message but also the trustworthiness of its source (=epistemic vigilance). But that capacity can be hijacked… …and is being hijacked by Russian propagandists. @a-marie-sci.bsky.social describes how: buff.ly/n8ydY2Z

One sees articles with titles like “everyone hates AI”. They don’t mention the power of LLMs for accessing expert information. Is it possible that attitudes towards AI (warm vs cold) have become a single item measure of the strength of people’s accuracy/epistemic motivations?

Something this sad Arday story reminded me of is that it's possible to have ppl who do their best to do actual social Science (learn methods, coding, pre-reg, replication), while others will just do 'auto-ethnographic' papers based on a few introspections.

Hot take: Politically motivated thinking is common in face to face conversations because people want to influence their informational environment (starting with the people they're chatting with) and get triggered by their partners' speech.

🔥 All political movements, left and right, engage in speech repression when it favours their interests and worldviews, or offers status-enhancement opportunities. Even those claiming to be “pro-freedom”. The default is a state of *moral hypocrisy*.
