What is BAHFest?

The first ever Festival of Bad Ad Hoc Hypotheses (BAH!) was held on October 6th, 2013 at MIT's Kresge Auditorium. It was the first of what we hope will be many celebrations of well-argued and thoroughly researched but completely incorrect evolutionary theory. Our brave speakers presented their bad theories in front of a live audience and a panel of judges with real science credentials, who together determined who took home the coveted sculpture of Darwin shrugging skeptically. And eternal glory, of course.

Here’s the comic that inspired the event:


BAHFest 2013

After a rescheduling, the first-ever BAHFest was held in MIT's Kresge Auditorium on the evening of October 6th, 2013 in front of over 1000 attendees. The event was hosted by Ben Lillie of Story Collider. Click on a presenter's name to watch their talk!

Our brave presenters:

Our esteemed judges:

  • Robin Abrahams
  • Dany Adams
  • Richard Wrangham

BAHFest was put on by Zach Weinersmith (cartoonist of SMBC), breadpig, and MIT's Lecture Series Committee. It was sponsored by the EvoS Consortium and This View of Life magazine (Editor-in-Chief David Sloan Wilson). We were also proud to be part of the Cambridge Science Festival.

How do I submit?

Submissions for BAHFest East and West 2014 have closed! Follow us on Twitter or Facebook to keep up to date on future calls for submissions.

What’s in a good theory?

Our initial selection readers AND our judges will be grading theories on four criteria:

  1. Force of Science - how much “scientific” information was brought to bear (graphs, real citations, “research” etc.)
  2. Artistry - how unexpected and clever the idea and presentation are, and how well the presentation is delivered.
  3. Parsimony - the simplest theory that explains the most data is best.
  4. Strength of Defense - how well did you defend your views to the judges. Please note - being funny is not a good defense. We want to see you actually defend your terrible terrible theory!

Is BAHFest a family-friendly event?

It’s evolution, so there’ll no doubt be plenty of talk of sex. However, we're working with the speakers and will discourage anything overly grotesque or horrifying.

We hope to see you there!

BAHFest would like to thank:
