Skepticism - the critical analysis of claims lacking empirical evidence.

Not empirical evidence - you saying so; your mate saying so; 'that' video on youtube; Wikipedia; Infowars; the Daily Mail; "51% of 75 women agree"; and anything "scientifically backed".

"Skeptics in the Pub is an informal social event designed to promote fellowship and social networking among skeptics, critical-thinkers, and other like-minded individuals. 
The usual format of meetings includes an invited speaker who gives a talk on a specific topic, followed by a question-and-answer session. Other meet-ups are informal socials, with no fixed agenda. The groups usually meet once a month at a public venue, most often a local pub. There are now more than 100 different "SitP" groups running around the world."

Barnsley SitP meet on the first Thursday of each month in The Old No.7 cellar bar.
