Bigger venue. Bigger stars. Bigger ideas. Bigger fun.

Las Vegas, October 18 – 21, 2018

CSICon is already one of the planet’s premier skeptics conferences, where hundreds of critical thinkers come to Las Vegas, the city of illusions, to hear from the leading lights of science and skepticism. For 2018, we want CSICon to be bigger than ever.

Note: Our room block is now full for the Westgate Hotel, as is our overflow room block at Harrah’s. We understand that you may be able to book rooms at either The Westgate or Harrah’s, however our special conference rate will no longer be in effect. The “Book Now” button will take you to the reservation window for Harrah’s.

Come to Las Vegas October 18-21 at the Westgate Resort and Casino to see:

  • The brilliant and hilarious Stephen Fry on stage with Richard Dawkins
  • A special Sunday morning conversation featuring James The Amazing Randi with Massimo Polidoro
  • A talk by Steven Pinker on the ideas behind his new book Enlightenment Now

PLUS: New York Times science writer Carl Zimmer, psychologist and memetics expert Susan Blackmore, the “SciBabe” Yvette d’Entremont, virologist and advocate for science-based medicine Paul Offit, and many more, along with comic-musician George Hrab serving as master of ceremonies, a magic show from Banachek, author book signings, and, of course, a Halloween Costume Party.

It’s true, conspiracy theorists, quacks peddling fake medicine, and the deniers of evolution, climate change, and vaccine science are bigger threats than ever.

With CSICon 2018, let’s show them that they just met their match.

We’ll see you in Vegas!
