Join us at CSICon 2019

October 16-20 at the Flamingo Resort in Las Vegas

People are finally starting to wake up.

  • Anti-vaxxers: Denounced as a danger to public health.
  • Climate science deniers: Exposed as ideological zealots.
  • Celebrity psychics: have been caught red-handed using trickery.
  • Homeopathy: Debunked as fake medicine.
  • Flat-Earthers: …seriously?

Skeptics must seize this moment, as misinformation is colliding with reality in plain sight. Now is the time for the brightest minds in science and reason to come together to turn the tide against pseudoscience, conspiracy theories, and alternative facts.

And naturally, we should do it in Vegas. It’s more fun that way.

“It is easier to judge the mind of a man by his questions rather than his answers.” — Pierre-Marc-Gaston, duc de Lévis (1764-1830)

We like answers. We like to know them and to give them. Sometimes we want others to think we are smart or knowledgeable, so we jump to give answers rather than ask questions.  And the questions we do ask are sometimes based more on our personal assumptions and biases than they are about getting to the real answer.

Skeptical thinking is more about asking good questions than knowing good answers. In this interactive workshop, we will practice methods for posing questions that lead to better understanding and new ideas, while avoiding bias and hasty assumptions.

Skepticism Activist

This workshop is for the skeptic that is interested in making a difference by finding realistic and practical methods of fighting back against the nonsense we see in society every day. Mark Edward and Susan Gerbic are involved in hands-on activism interactions. Focusing on the current results of their activities since CSICON 2018, their successful psychic stings on “grief vampires” will be discussed in detail. For the most recent results visit and read the section on grief vampires under the Susan Gerbic tab with special attention to the NYTimes article by Jack Hitt and the Holy Koolaid video interview.

Our world is full of strange mysteries; ghosts, monsters, UFOs, alleged miracles, and so on. In this workshop, Kenny Biddle and Jim Underdown will share some of the techniques they employ to investigate and solve these extraordinary mysteries. They’ll discuss tips and techniques for investigating, and do a deep-dive into a few case files that demonstrate how these techniques were instrumental in breaking the case and solving the mystery. The workshop will wrap up with a Q&A session, giving attendees an opportunity to pick the brain of the hosts.

It is imperative to understand why we fall for bullshit if we are ever to effectively overcome it. I will discuss the cognitive science of human beliefs with a specific focus on political fake news and new-age woo (“pseudo-profound bullshit”). I propose that the all-too-human propensity to reflexively rely on our gut feelings and intuitions in lieu of more analytic thinking processes is the key to understanding why we fall for bullshit.

An insider-outsider look at the Facilitated Communication movement—how it works, who really benefits, why critical reviews have not stopped its progress, and what we can do about it.

Presented by

Janyce L. Boynton

Artist, Educator

I lead a team of scientists focused on brain theory, specifically, how the neocortex works. In the past few years we have made dramatic progress on this problem. In this talk I will give an overview of what we have learned and propose how brain theory might impact the future of AI and robotics. I will end with a discussion of what can go wrong, how the brain can form false beliefs and why it doesn’t always behave rationally.

All of our work is published in open access peer-reviewed journals. You can find links to these and other resources at

Being a skeptic is not just about correcting others and protesting for science, it is a daily and very personal thing. Professor Troy Campbell looks beyond “the issues” at the rich beautiful existence of being a skeptic. Skepticism is an orientation toward the world, where you just keep asking more questions and looking for more detail. And that orientation makes you a better and more successful person. Professor Campbell talks about how he is skeptic everyday an academic, a creative at Disney Imagineering and Netflix Insights, as well as when interacting with strangers and just planning dinner parties. In a skeptical existence, he says one sees more of existence, because you are constantly asking what else is there. And yes, he says, some non skeptics may perceive that their life is ‘full’ but we know that those people have seen only a few drops of reality. He will close will a call show the world that skepticism isn’t here to critique them but offer them a better and fuller existence on a society but also a personal level.

11:30 AM | David Mikkelson Presentation

Homeopathy, naturopathy, acupuncture, and subluxation-based chiropractic are all grounded in pseudoscience, yet practiced daily in the U.S. without sanction. Why? Because lawmakers have incorporated pseudoscience into the law, permitting the sale of healthcare products and services that have no plausible basis in science and no evidence of effectiveness to an unknowing public. We’ll look at how these laws are made and operate in practice and what skeptics can do about it.

Human-caused climate change represents arguably the greatest threat we face as a civilization. Efforts to attack and deny the scientific evidence have constituted a major impediment to action over the past two decades. At a time when we appear to be moving past outright denial of the problem, another obstacle has emerged on the scene: Doomist framing that exaggerates the threat in such a way as to make catastrophic changes seem unavoidable. Such framing can lead us down the very same path of inaction as outright denial of the problem. It is important, in the end, to emphasize both urgency AND agency in climate change communication efforts.

The most awarded mentalist in history is back at CSICon! Described as the “Cream of the Crop” when it comes to entertainers, Banachek is undisputed as the world’s greatest mindreader. Astounding audiences across the globe, his talents are so incredible that he is the only mentalist ever to prove to scientists that he possesses “authentic ‘psychic powers’.” Luckily Banachek is also a skeptic and debunker of charlatans.

Join him for a show full of mind reading, predictions, and telekinesis. You may even learn the skills of a mentalist yourself!

In this talk, Dr. Lilienfeld will examine recent psychological theorizing and research, including some from his laboratory, on the poorly understood construct of intellectual (epistemic) humility, which refers to the extent to which individuals are aware of their own cognitive fallibility, including their propensity toward biases. He will discuss the potential implications of intellectual humility for political and religious extremism and polarization, as well as for scientific and unscientific thinking. He will also discuss how intellectual humility may help to elucidate the differences between healthy and pathological skepticism and examine its implications for the skeptical movement writ large.

Scott Lilienfeld

Dating back to Darwin himself, the “argument from poor design” holds that examples of suboptimal structure/function demonstrate that nature does not have a designer. Perhaps surprisingly, human beings have more than our share of quirks and glitches. Besides speaking to our shared ancestry, these evolutionary “seams” reveal interesting things about our past. This offers a unique accounting of our evolutionary legacy and sheds new light on how to live in better harmony with our bodies, in all their flawed glory.

It’s time to open our eyes to the skeptical deeds that evade our awareness. Television shows hosted by skeptics; a university-based office dedicated to protecting the public from pseudoscience; a homeopathy degree cancelled due to skeptics’ engagement with the media…   these accomplishments will inspire you to join an active defense against misinformation!

Naturopaths have defined their brand of medicine using a set of “healing” principles that sound pleasant, but really describe an archaic and sometimes twisted understanding of medicine. Having been a former naturopathic “doctor,” I can say that the overwhelming majority of naturopathic care relies extensively on dubious alternative therapies, rather than established protocols based on medical and scientific research. When it comes to naturopathy, “nature” always trumps the oath to do no harm. Join me for a deconstruction of naturopathy’s defining principles and what to do about the growing trend of natural medicine.

In one of astronomy’s greatest modern triumphs, we now know that there are a trillion planets in the Milky Way.  Roughly one in five may be similar to Earth.  So with so much cosmic real estate, there must be someone out there, right?  Science agrees, and may soon augment opinion with discovery.  But what about the fact that one-third of the public is convinced that aliens are busy visiting Earth?  What does a SETI researcher tell the hundreds of people who phone him every year to report sailing saucers and unauthorized assaults on their persons?  Is logic and a recourse to data the best approach to dealing with the UFO believers, and does it even matter?

For several decades, I have been manufacturing memories in unsuspecting minds. Sometimes this involves changing details of events that someone actually experienced. Other times it involves planting entire memories for events that never happened – “rich false memories.” People can be led to believe that they did things that would have been rather implausible. They can be led to falsely believe that they had experiences that would have been emotional or traumatic had they actually happened. False memories, like true ones, also have consequences for people, affecting later thoughts, intentions, and behaviors. Can we tell true memories from false ones? In several studies, I created false memories in the minds of people and then compared them to true memories…  Once planted, the false memories look very much like true memories – in terms of behavioral characteristics, emotionality, and neural signatures. If false memories can be so readily planted in the mind, do we need to think about “regulating” this mind technology? And what do these pseudomemories say about the nature of memory itself?
