Are a majority of Americans actually racist?, with Leonie Huddy

A talk with political scientist Leonie Huddy on the topic of research on American racism and prejudice.  I was interested in discussing framings like this one from a 2012 USA Today article: "U.S. majority have prejudice against blacks" and ask her if such confident framings were justified based on the research, or if they were over-stated and irresponsible. Topics discussed: the ambiguity that can be present when attempting to study prejudice, especially for studies that seek to measure it rather indirectly; how worst-case and pessimistic framings and interpretations of studies and surveys can add to us-versus-them political animosity.

Inherent aspects of social media that amplify divides and bad thinking

This is a piece that I, Zach Elwood, wrote about the ways in which social media (and internet communication more broadly) may be amplifying us-versus-them polarization and extreme thinking.  Much of the mainstream coverage of how social media may be amplifying divides and making people unhappy is on product-specific features and algorithms. But what if there are inherent aspects of internet communication that amplify animosity and bad thinking, no matter the format or structure of the tool? What if "the medium is the message" in some way? This piece examines the psychological processes by which social media may be deranging us and talks about strategies for reducing unhelpful group-versus-group animosity.

Is paying so much attention to politics hurting us?, with Chris Freiman

If you're someone who pays a lot of attention to politics, but feels that doing so makes you miserable, this may be an important listen. What if someone were to tell you that paying attention to politics is not a morally correct way to spend your time and energy? Political philosopher Chris Freiman is the author of Why It's OK to Ignore Politics. He makes a case that paying a lot of attention to politics is often a waste of time, and may even be immoral compared to other ways you could be spending your time and energy.

Now that GOP has become the party of "the election is illegitimate", things have swung the other way and it is Democrats who seem unwilling to acknowledge flaws that many on that side were willing to talk about up until recently. We talk about how politics and polarization can impact attempts to solve election security problems, and she gives insights on the problems she sees with elections.

Does blaming "media" help us avoid personal responsibility?, with Elizaveta Friesem

Elizaveta Friesem thinks and writes about media and how we relate to it. Her recent book is called "Media Is Us" and it examines the idea that media is not something "out there" but more something that is part of us, something that happens internally, similar to any other human communication. And perhaps this means that acting as if "media" of various sorts is to blame for various problems is a simplistic way to view the world. We talk about the need for personal responsibility for how we consume media, power dynamics in society, the power of empathy and understanding others, and more.
