What we’re about

"Scientific Skepticism" is a social movement that began in the 1970s to investigate & debunk topics like ESP, faith healing, astrology, UFOs, ghosts, and other "paranormal" phenomena. Skepticism was essentially a pro-science movement in reaction against the rise of New Age mysticism on the left and Christian fundamentalism on the right. Over time, the skeptic movement has addressed other debates about the dividing lines between science & pseudoscience, medicine & quackery, history & mythology, reason & faith, etc., and has tried to ascertain why people often hold irrational beliefs and how they might be persuaded to adopt more evidence-based beliefs.

"Skeptics In The Pub" started in London in 1999 as an informal social event designed to promote fellowship and social networking among scientific skeptics, free thinkers, rationalists, science enthusiasts, and other kindred spirits. The group is now held in various forms around the world, with well over a hundred local chapters.

The Philadelphia chapter of "Skeptics in the Pub" was founded back in 2014 and hosts bi-weekly group discussions on a range of topics related to science and rationality. There's several things that set our group apart from many other skeptic groups out there:

(1) While most Skeptics in the Pub chapters rely on guest lecturers, we're primarily an intellectual discussion group. That means that our regular bi-weekly meetups have a discussion topic and require some preparation and involve active participation.

(2) Most other chapters of Skeptics in the Pub host their events in "pubs" as the name suggests, but we found them to be too loud and shifted to cafes in 2017. However, since the COVID pandemic began in 2020, most of our events have moved online. Even with the pandemic over, we've found that online events have a big advantage in terms of being able to attract participants from all over America and even overseas, rather than just catering to people in the Philly metro area.

(3) When it comes to addressing pseudoscience & the paranormal, we tend to address controversies among serious scientists & scholars that aren't clear cut rather than just debunking fringe beliefs like homeopathy, Flat Earth, Bigfoot, ghosts & alien abductions for the hundredth time. We typically only address pseudo-scientific beliefs once they become widespread enough to cause major risks or interfere with major benefits to society (e.g. the anti-vaccine, anti-flouride, anti-GMO, anti-nuclear power, AI doomer, AIDS denial, COVID denial, and climate change denial movements). We also try to understand the social & psychological factors behind pseudoscientific beliefs.

(4) While we champion the scientific approach to empirical questions, we're careful to avoid a common pitfall of some skeptic groups -- i.e. "scientism" -- the application of science to non-empirical questions in fields like ethics, aesthetics & political philosophy. Also, while we generally defer to the scientific establishment, we also occasionally act as critics when it comes to issues like funding biases, academic fraud, and the replication crisis.

(5) When we cover conspiracy theories, we tend to focus less on bizarre beliefs about "Men in Black" and the "Illuminati" in favor of somewhat more plausible allegations of political corruption, corporate malfeasance, police cover-ups, covert military actions, domestic spying, etc. We also look at how low science literacy & internet echo chambers lead many normal people to go beyond realistic concerns about Big Government & Big Business and embrace irrational conspiracy theories.

(6) We tend to cover "pseudo-history" more than other skeptic groups. While the skeptic movement has done a fairly good job debunking far-out claims about "ancient aliens" & lost civilizations like Atlantis, we tend to focus more on dubious historical claims that have bigger implications for modern-day politics like the various cases of genocide denial (e.g. Holocaust, Holodomor), Neo-Confederate "Lost Cause" apologetics about the Civil War, the 1619 Project's revisionism, the antisemitic theories of the Black Hebrew Israelites & the Nation of Islam, and historical conspiracy theories about Pearl Harbor, the JFK assassination, the Apollo moon landing, the 9/11 attacks, etc. We also occasionally cover lighter topics related to mythology, folklore & urban legends from both a historical & socio-psychological perspective.

(7) When we address problems with the news media, instead of debunking obvious hoaxes from junk tabloids & "fake news" websites, we tend to focus on problems within the mainstream media coverage, such as the exaggeration of scientific findings in "pop science" journalism, political biases that corrupt journalistic objectivity, and the fear-mongering that drives "moral panics". We also try to help members cut through conflicting accounts of highly polarizing events, like foreign wars or domestic social turmoil, and find out what's probably true and what's unwarranted speculation or outright disinformation.

(8) Although we occasionally address ethical & political issues, we do so from a non-partisan, empirical approach. Any politician, pundit or political party that makes claims that are unsupported by logic & evidence are open for criticism. There's also no expectation that members have specific ethical or political commitments, beyond a commitment to the use of reason & empiricism to make arguments and support for free inquiry & open debate. Whether or not atheists should adopt specific secular philosophies like "ethical humanism", "objectivism", "transhumanism", "longtermism", "effective altruism", etc., or even whether or not a scientific worldview can support certain ethical or political principles is an open question as far as this group is concerned.

(9) While most skeptic groups double as atheist groups, this meetup doesn't require members to have any particular position on abstract metaphysical questions like the existence or non-existence of a "higher power” or "ground of being", free will vs determinism, the nature of the "self", the hard problem of consciousness, panpsychism, the simulation hypothesis, the multiverse, etc. While many of the supernatural claims made by traditional organized religions are either unfalsifiable or don't withstand scientific scrutiny, the skeptic movement's major figures have had a variety of metaphysical positions, from Carl Sagan's pantheism to Richard Dawkins' anti-theism, and from Paul Kurtz's "ignosticism" to Martin Gardner's "fideism". When we cover religious issues, rather than debating the existence of God or creationism vs evolution for the thousandth time, we often focus on topics related to the psychology & sociology of religion, or we look at the ways in which the frontiers of physics can inform metaphysical speculation.

If this sounds interesting to you, we hope you'll join us!

    Event Description:
    Get ready for something spellbinding: A look at various depictions of witches as reflections of ideas about female sexuality, independence, agency, and power.

    Offering up this pre-Halloween treat will be folklorist Linda Lee, who previously has given excellent talks at the Black Squirrel Club in Philadelphia’s Fishtown on dark Christmas folklore and the goddess Persephone.

    We’ll start with an introduction to witches from European folklore, fairy tales, and legends. You’ll learn how they’re generally portrayed as powerful, solitary, and defiant figures who can be either helpful or harmful. They may appear as mothers, helpers who aid a hero on a quest, or monsters to be vanquished. They can represent a threat to the community by snatching children or pilfering cows’ milk.

    Individual witches who will be conjured up include the child-eating witch from Grimms’ “Hansel and Gretel” and Baba Yaga, the ambiguous witch of Slavic folklore who lives in a hut on chicken legs and flies around with a mortar and pestle.

    Lee will then contrast such fictional depictions with the ideas about witches and witchcraft espoused by Christian demonological thought.
    You’ll learn how witches are described by early modern sources like Malleus Maleficarum, the 15th-century treatise on witchcraft which also served as a witch hunters’ manual. Such texts present witches as entirely malevolent figures who gain magical powers through a pact with the Devil (usually signed with menstrual blood). The witches in them are believed to use a special ointment that allowed them to fly to a Witches’ Sabbath, where they dance and perform demonic rituals.

    You’ll see how such ideas were visually reinforced through engravings, woodcuts, and drawings, by artists like Albrecht Dürer, that depicted naked women riding broomsticks and dancing with devils.

    You’ll come away with a better understanding of why witches are among the most versatile, notorious, and enduring figures from fairy tales and legends and remain an iconic part of contemporary Halloween traditions.

    About Profs & Pints:

    Commonwealth Club Event: "Abuse of Power" by Mark Shaw

    Online

    Join the Commonwealth Club of California on Monday, Dec. 8, 2025 to hear Mark Shaw discuss how he thinks Mafia Dona Carlos Marcello used "patsies" to mastermind the deaths of JFK, Dorothy Kilgallen and RFK, which he details in his new book, Abuse of Power: Connecting Robert Kennedy's Assassination with the Murders of JFK and Dorothy Kilgallen Exposes Who Was Responsible and Why Sirhan Sirhan Deserves a New Trial.

    HOW TO WATCH:
    This event is $10 for online tickets, and you must register at the link below, at which point you'll be emailed a link to the online event -
    https://commonwealthclub.my.salesforce-sites.com/ticket/#/instances/a0FVb000008MQLpMAO

    NOTE: This event is free for members of the Commonwealth Club of California. Membership costs just $10/month and you can cancel at any time. To become a member, go to: https://www.commonwealthclub.org/membership

    EVENT DESCRIPTION:
    Bestselling author and noted historian Mark Shaw returns to Commonwealth Club World Affairs to discuss his latest research and his newest book. They strengthen his conclusion that New Orleans mafia don Carlos Marcello was the point person pulling the strings behind the murders of JFK and famed journalist Dorothy Kilgallen. And, for the first time, he also links Marcello to the murder of Robert Kennedy. In his previous books, Shaw established the connections between Marcello, Oswald, Ruby and Kilgallen and Marcello’s use of Kilgallen’s lover to silence her before she could expose Marcello’s involvement in the JFK assassination. In his latest book, Abuse of Power, Shaw lays out compelling evidence that Marcello’s pattern of using patsies to exact his revenge culminated in his setting Sirhan Sirhan up to take the fall for the assassination of RFK on June 6, 1968.

    Shaw’s new research includes his examination of the JFK assassination records recently released by the federal government. In those files is a December 1985 FBI transcript in which Carlos Marcello was taped “confessing” to his role in JFK’s death: “Yeah, I had the son of a b---h killed. I’m glad I did. I wish I could have done it myself.”

    Shaw investigates whether Marcello decided on a similar approach when it became clear in early 1968 that RFK could become president. Shaw says that since Robert Kennedy, as attorney general, had ordered Marcello deported in April 1961, charging him with racketeering, Marcello had no intention of allowing RFK to get in his way again and so had Bobby killed.

    Shaw alleges that Marcello used his “associate,” mobster Mickey Cohen, who controlled the Southern California racetracks, including Santa Anita, and knew the layout of the Ambassador Hotel where RFK was killed, to “recruit” 24-year-old Sirhan just as the mafia don had recruited Lee Harvey Oswald to assassinate JFK. Evidence for Shaw’s allegation is a never-before-published, eyewitness, video-taped account from John Shear, a celebrated paddock captain at Santa Anita Racetrack. He had hired Sirhan to work as a “hot walker” at the racetrack and considered him “easily manipulated.”

    Shortly before RFK was killed, Shear noticed that Sirhan was all dressed up, had money and was hanging around nearby Hollywood Park Racetrack with “two hoodlums” despite being poorly paid and having gambling debts. Shaw says that shortly after RFK’s murder, it was Shear who first identified Sirhan for the LAPD and the FBI from the photo of Sirhan being shown on TV—but Shear was never contacted by either the LAPD or the FBI about Sirhan, pointing to a cover up.

    Then, just as twice before regarding JFK’s and Kilgallen’s deaths, the trail of evidence quickly and suspiciously went cold. Join us as Shaw makes sense of the newfound evidence and heats up his call for justice in the murders of JFK, Dorothy Kilgallen and Robert Kennedy.

    ABOUT THE SPEAKERS:

    • Mark Shaw is an investigative reporter, former defense attorney, a former legal analyst for USA Today and CNN, and the author of over 20 books. To date, Shaw has published six books touching on the JFK assassination including Melvin Belli: King of the Courtroom in 2007 and The Poison Patriarch: How the Betrayals of Joseph P. Kennedy Caused the Assassination of JFK in 2013. Nearly three years later, Shaw penned the bestseller, The Reporter Who Knew Too Much (2016) about the life and times and the death of legendary media icon Dorothy Kilgallen and her coverage of the assassination. He followed up that book with Denial of Justice (2018) which exposed never-before-published evidence about the assassination and Ms. Kilgallen being denied justice when she was murdered. He tied these narratives together in his books Collateral Damage: The Mysterious Deaths of Marilyn Monroe and Dorothy Kilgallen, and the Ties that Bind Them to Robert Kennedy and the JFK Assassination (2021) and Fighting for Justice (2022), and updated his theories with more evidence in his latest book, Abuse of Power (2025).
    • George Hammond, the moderator, is a retired lawyer who now serves as the Chairman of the Humanities Forum at The Commonwealth Club of California. He's the author of six philosophical books on issues in rational idealism, theoretical physics, Plato's theory, early Christianity, the Soviet Union, psychology, and constitutional law.
