Skeptics on the Fringe has just completed its sixth year, making it the longest-running and most varied festival of free Skepticism in the world.

What is it?

We bring Science, Reason and Critical Thinking to the wolrd’s biggest Arts Festival by presenting a different free talk every night on the Edinburgh Festival Fringe.

Four Star

With 4* reviews from Broadway Baby and Three Weeks, we’re a recognised part of the Fringe.


We were proud to win Skeptic Magazine’s 2013 Ockham Award for Skeptical Outreach.


SotF serves three broad principles:

  • Reaching people who don’t normally identify as Skeptics

Our audience varies from night to night,  with fringe-goers who want a break from stand-up, people who are interested in the particular topic, “returners” who enjoyed previous talks and our regulars who come throughout the year.

  • Supporting diversity and grassroots skepticism

We strive to strike a balance between “big name” speakers who are well known, academics who are true experts in their fields, and grassroots skeptics who are just starting out. We support speakers who are under-represented such as women or who are from minority groups.

  • Lowering the barrier for entry

All Skeptics on the Fringe events are free.  All someone needs to come to our events is an enquiring mind or interest in the topic. No one profits but Skepticism as a whole.

Skeptics on the Fringe 2015

This year we asked Hey Dude, where’s my Hoverboard?

In the year that was 30 years ahead when Back to the Future went back to the future, we asked is the future all it’s cracked up to be?

Our speakers are always a mix of the stars of the skeptical world, academics and specialists, and grassroots speakers from local Skeptics in the Pub societies.
