Shadow of a Doubt - January 2023


January 2023

NCAS Public Lecture Series

A Discussion of the Documentary Film Science Friction

 YouTube Live Event with Q and A 

Brian Dunning
Executive Producer / Co-Writer, Science Friction

Saturday, January 21, 1:30pm US/Eastern (UTC-05:00)

NCASVideo YouTube Channel: 

This month, NCAS presents a different kind of event. We invite you to watch the documentary Science Friction BEFORE January 21, 2023 (see below for ways to watch). Then join us on Saturday, January 21 at 1:30 PM ET for an online Q & A with Executive Producer Brian Dunning.

From the film's website:

"Finally, a documentary about scientists who get misrepresented by the media.
Those TV documentaries you see, and the science experts they feature? Did you know that producers often edit them out of context, and twist their words, to make it seem like they promoted some pop sensationalism instead of the real facts?

Science Friction exposes this practice and gives the scientists a chance to clear the record."

Executive Producer / Co-Writer Brian Dunning is the host of Skeptoid, the award-winning weekly science podcast. Since 2006, Skeptoid has been revealing the true science behind popular misinformation and urban legends.

Full information about this documentary can be found at

Sad News

Harriet "SkepDoc" Hall, MD has unexpectedly passed away at age 77:

Dr. Hall was a contributing editor to both Skeptic magazine and the Skeptical Inquirer. She was a weekly contributor to the Science-Based Medicine Blog and was one of its editors. This is another blow to the skeptics community, happening just a couple of months after the passing of Skeptical Inquirer editor Kendrick Frazier.

Teller's "Tempest" Extended to January 29

"The Tempest" run at Round House Theatre in Bethesda has been extended from January 15 to January 29.  Teller is credited for co-directing/co-adapting and magic.  (Yours truly, Scott Snell, will be celebrating Friday the 13th by attending that evening's performance!)

Happy Friday the 13th!
NCAS has no events planned for Friday, January 13, but encourages our members to celebrate the silliness of superstition responsibly.  Wear eye protection if you smash a mirror, be careful when walking under a ladder, etc!

AmazonSmile: Thanks to our members who are supporting NCAS!
When shopping at, you'll find the same low prices, vast selection, and convenient shopping experience as, with the added bonus that a portion of the purchase price (0.5%) goes to NCAS! It's simple and automatic, and it doesn't cost you anything!

AmazonSmile's disbursements to NCAS in the third quarter of 2022 came to $51, meaning that over $10,000 of purchases were designated in support of NCAS.  (As an example of how NCAS can put that money to good use, it's more than enough to cover two hours of a Montgomery County lecture room rental.)

Thanks again to our members who have chosen to support NCAS!
