@KAnthonyAppiah refers to the extended mind in @NYTmag: "Our beliefs depend not just on our own brains but also on the social worlds we live in. One way of capturing this truth is what some philosophers have called the extended-mind hypothesis.

Our minds don’t simply repose between our ears (the argument goes) but extend into the world around us, a world that may or may not include Fox News, Parler, talk radio, a voluble workplace colleague, filtered Twitter feeds and the like.

What’s obvious is that people can be epistemically disadvantaged by gaining their beliefs from social networks that are radically unreliable. We get many of our false beliefs in the same way we get true ones: by listening to the views of people we trust.

You can be partially responsible for being in an unreliable network if there are signs that something is wrong and you don’t examine the possibility that it’s misleading you. But the misjudgment here may not reflect bad moral values."

Are we responsible for the state of our extended minds? https://www.nytimes.com/2020/12/01/magazine/should-i-stop-speaking-to-my-trump-supporting-friends.html
