People Who Read People: A Behavior and Psychology Podcast
Zachary Elwood
This is a podcast about deciphering human behavior and understanding why people do the things they do. I, Zach Elwood, talk with people from a wide range of fields about how they make sense of human behavior and psychology. I've talked to jury consultants, interrogation professionals, behavior researchers, sports analysts, professional poker players, to name a few. There are more than 135 episodes, many of them quite good (although some say I'm biased). To learn more, go to PeopleWhoReadPeople.com.

Why they riot: A Portland-based antifa explains their militant actions
An interview with a self-described anti-fascist who has taken part in the more militant and unlawful aspects of the BLM-focused protests and riots that have occurred in Portland, Oregon in the wake of George Floyd's death. This person has also taken part in physical confrontations with alt-right pro-Trump groups, like the Proud Boys. They talk about the motivations and goals of their violent activities, why violent protest is justified, and their justification for getting in violent confrontations with groups like the Proud Boys.

Was the Cambridge Analytica scandal mostly bullshit?
You've probably heard about how Cambridge Analytica used access to the Facebook data of millions of U.S. citizens and advanced digital advertising wizardry to essentially “hack” Americans’ minds and deliver a surprise presidential victory to Donald Trump. This depiction of Cambridge Analytica as nefarious data geniuses has been shared in many news stories (probably most prominently in the documentary The Great Hack).
But what if this perception is untrue? What if Cambridge Analytica were exaggerating their behavior-influencing abilities, as many companies do? And what if our perceptions of CA as geniuses of digital influence is based on people accepting those exaggerated claims uncritically?
That is the stance of political scientist Dr. Dave Karpf, and in this episode he explains why. Learn more about your ad choices. Visit megaphone.fm/adchoices

From Tourette's to personality disorders: Examining offensive, taboo speech factors
A talk with psychologist and expert on cursing Timothy Jay about some lesser known factors involved in people saying offensive things. This episode has a focus on the phenomenon of videos widely shared on social media showing people saying or doing offensive things (including racist rants). We discuss factors that can nfluence offensive behavior, including Tourette's Syndrome, brain disorders like Alzheimers, substance abuse, mental illness, and personality disorders. Topics discussed include: how cursing can be governed by a different part of the brain than “normal” language; the nature of Tourette’s Syndrome, and why some TS sufferers (a small percentage) exhibit offensive language or behavior and most do not; why people with mental illness and/or personality disorders may lash out in aggressive and offensive ways as a coping mechanism; how we as a society need more understanding and empathy for the factors that can lead to outrageous and offensive behavior; social media's role in making conflict and taboo-transgression into entertainment.

Can you predict schizophrenia by studying language?
An interview with psychology researcher Neguine Rezaii about her work using machine learning to predict conversion in teenagers from prodromal symptoms to psychotic episodes. The two language patterns found in the subjects' speech were 1) a low semantic density (i.e., little meaning), and 2) speech related to sound or voices. Topics discussed include: how exactly they determined “low meaning"; how the algorithm found, on its own, indicators related to sound-related speech content; the future of using machine learning and automatic diagnosis tools in psychology and therapy; theories that might help explain these findings.

Can brain scans identify people's thoughts?, with Marcel Just
I talk with Marcel Just about his research using fMRI brain imaging to identify brain activity associated with specific thoughts: for example, identifying that a subject is thinking about an apple, or about death. Dr. Just and his team have been twice featured on the show "60 Minutes." Topics discussed include: the nature of human thought; how much is our consciousness individual thoughts vs many things firing at once?; why brain activity for specific thoughts and emotions trigger specific areas of the brain in consistent, predictable ways; why thoughts and emotions activate the same types of patterns for so many people, even across language divides; how fMRI works and why it is a good choice for this type of work (versus EEG, for example); the state of this technology, its potential applications, and what its practical limitations are.

What brain scans reveal about trauma, suffering, and therapy benefits
A talk with Dr. Rob Tarzwell about his research using SPECT neuroimaging to find indicators of traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). This work was voted by Discover Magazine as one of the top 20 science stories of 2015. Topics discussed include: the ways physical harm to the brain (e.g., traumatic brain injury) shows up differently in brain imaging compared to more psychological conditions like PTSD or depression; the differences between different types of brain imaging (PET, SPECT, fMRI) and their strengths and weaknesses; Tarzwell's research showing the effects of therapy in brain scans.
