Why hasn’t big data & data crowdsourcing disrupted healthcare?, with Jamie Heywood

In this episode of the People Who Read People podcast, I interview Jamie Heywood (his Wikipedia page), about the benefits and challenges of conducting medical/health research using crowdsourcing of real-world, patient-reported data directly from the public. Heywood got his start on this career path when his brother was diagnosed with ALS; Jamie wanted to do everything he could do to maximize Stephen’s chance of survival. Jamie started ALS TDI to research and test treatments for ALS. Later, Jamie was co-founder and CEO of PatientsLikeMe, a platform for collecting real-world medical data directly from patients and giving them a network to share learnings about their conditions and treatments. He also is co-founder of biotech company AOBiome.

In this interview, Heywood discusses the strengths and challenges of big-data approaches to collecting medical data from the public, why such tactics haven’t been as revolutionary or mainstream as the potential suggests, and thoughts on healthcare challenges we face in general. Episode links:

Reading online dating profile indicators/tells, with Celia

First of two interviews I did about online dating. This is an interview with an acquaintance, Celia, about her experiences with online dating. We focus on the indicators/tells she uses when looking at online dating profiles/pics to determine if someone might be a good match for her. Episode links:

Some topics and research discussed:

  • Are there certain types of photos (like guys holding fish) that influence her to contact or not contact someone?
  • Are there certain written bio description approaches that are turn-offs?
  • What makes a guy’s photos “murder-y” and why is that a problem?
  • Discussion on how much info about yourself is too much in a dating profile (Celia discusses putting ‘vegan’ in her profile and the pros and cons of that)
  • 2007 study by Michael Norton et al showing that the more you learn about a person before meeting them, the more you’ll dislike them (familiarity breeds contempt).
  • 2013 study by Dan Jurafsky et al showing that the main indicator of a successful heterosexual date is the woman talking about herself.

How does not believing in free will affect one’s life?, with physicist Daniel Whiteson

A talk with Daniel Whiteson, a professor of physics and astronomy at the University of California, Irvine. He’s the co-author of “We Have No Idea,” about the unknown mysteries remaining in physics, and a co-host of the podcast Daniel and Jorge Explain The Universe.

I talk to Whiteson about free will. We talk a little bit about why we both think free will is unlikely to exist, but our main focus is on more psychological and emotional aspects: What are the results in our own lives of not believing in free will? What potential effects does lack of belief in free will have for people in general? Because the idea that free will doesn’t exist can make people anxious or sad, the idea that we are basically just automatons, the idea that our conscious experience of the world is like watching a movie we have no real control over.

A transcript is below.

There are many resources on free will out there, but here are a few that were either discussed in this episode or that I’ve found interesting:

On aphantasia (the lack of mental imagery), with Zach Elwood

I learned a few years ago that I have aphantasia, which is, to quote from Wikipedia: “characterized by an inability to voluntarily visualize mental imagery.” Before learning about this, I’d never believed people had actual visual mental images when they imagined things. Honestly, it’s still hard for me to imagine such a thing being possible. In June 2020, I was on Vikasan Pillai’s podcast The Untypical Podcast to talk about what it’s like to have aphantasia. I rebroadcast this episode for my own podcast. Here are episode links:

Questioning if social media plays a big role in political polarization, with Levi Boxell

A talk with Levi Boxell about his research into political polarization and the role social media plays in that. Boxell and colleagues did research showing that older Americans, who used the internet less than younger people, were more polarized and had more animosity towards the opposite political group than did younger people. While there could be less obvious, indirect processes at work, this seemed to show that the internet and social media were likely far from dominant factors in political polarization. Also, Boxell has done research comparing polarization change in different countries showing that because polarization isn’t happening consistently across many countries, the internet likely isn’t a primary factor.

We also discuss his research showing how there can be media bias in the choice of political leaders’ photos that news outlets choose, with negative bias leading to pictures with more negative emotion facial expressions and positive bias leading to choosing pictures with more positive emotion facial expressions.

“Opinion cascades” show some political party stances may be due to chance and initial conditions, with Dr. Michael Macy

In this episode of the podcast, I interview Dr. Michael Macy of Cornell University, whose research on “opinion cascades” show how some political group stances on issues can be rather arbitrary and due to initial conditions (a good summary of the study). Similar to how in many complex systems, slightly different initial conditions can lead to vastly different results later on, the early conditions in a country, including early opinion-holders and influencers, can influence a political party to be aligned with one or another stance on an issue. These early choices have a cascading effect, meaning that, for some issues, the political parties could hold reversed positions if things had gone a bit differently.

How does Facebook increase political animosity and polarization?, with Jaime Settle

In this episode of the People Who Read People podcast, I interview Jaime Settle, a political scientist and professor at William and Mary. A transcript of this talk is below.

Settle is the author of Frenemies: How Social Media Polarizes America. In that book, she summarizes thinking on American political polarization and describes the research she’s done, which shows that Facebook likely increases “psychological” or perceived political polarization, in the form of Facebook users becoming increasingly antagonistic towards members of the opposite political party.

I talk to Dr. Settle about what the psychological pathways are behind how social media polarizes us, what the downsides of extreme political polarization are, and what we can all do to decrease the most dangerous forms of this polarization.

Her latest work is Polarizing Polities: A Global Threat to Democracy, co-edited with Murat Somer (2019).

I talk to Dr. McCoy about what she views as the psychological and emotional forces behind extreme political polarization, how the United States is similar or different from other countries that have unraveled due to extreme polarization, and what might be done to solve these issues.

Examining the political impacts of violent protests and riots, with Dr. Omar Wasow

In this episode of the People Who Read People podcast, I interview Dr. Omar Wasow (here’s his Twitter), an Assistant Professor in the Department of Politics at Princeton University, and author of a paper entitled “Agenda Seeding: How 1960s Black Protests Moved Elites, Public Opinion, and Voting.” In that research, he found that civil rights-related violent activity in the United States in the 60s shifted public opinion and voting more conservative/Republican. I ask Dr. Wasow about his research, his methods for finding correlations, public reactions to his work (which have included some negative reactions), and what lessons are in his work for modern-day activists. We also talk about the role of news and social media in political movements, and about Trump-related worst-case scenarios.

This interview was the second I’ve done on the subject of protests and riots; in the last episode, I interviewed a Portland antifa/BLM protester.
