Merseyside Skeptics Society


Foundation

In February 2009, Marshall, Mike Hall and Colin Harris founded the Merseyside Skeptics Society. He commented that skepticism is "not about just saying 'no' to things, it's about thinking about them. And we use the
American spelling Despite the various list of dialects of English, English dialects spoken from country to country and within different regions of the same country, there are only slight regional variations in English orthography, the two most notable variati ...

, the word isn't as strongly linked to cynicism. It's not seen as being as negative as it is over here." In July that year, they launched the podcast ''Skeptics with a K'', which Marshall described as "a fairly-shambolic, overly-enthusiastic and snarky mix of science, skepticism and sarcasm". The idea for ''SwaK'' came from the conversations Hall and Marsh were having in the pub about news and ideas, such as a

10:23 Campaign

In January 2010, Marshall co-ordinated the 10:23 Campaign with Mike Hall and Andy Wilson to stage a mass overdose of homoeopathy outside branches of
Boots UK Boots UK Limited (formerly Boots the Chemists Limited) is a British health and beauty retailer and pharmacy chain that operates in the United Kingdom. It also operates internationally, including Ireland, Italy, Norway, the Netherlands, Thailand ...
in several major cities throughout the country, to publicly demonstrate the inefficacy of homoeopathic products and protest against their sale. In February 2011, he also co-ordinated the global 10:23 Campaign, during which protesters on all continents in 70 cities (at least 30 participants per city) overdosed on homoeopathy. He himself led the overdose on 5 February 2011 at 10:23 during QED 2011, the first annual skeptical conference in Manchester co-organised by the Merseyside Skeptics Society and the Greater Manchester Skeptics Society. In November 2019, Marshall was in Brazil to officially launch the campaign that aims to withdraw financial aid for homeopathy by the country's public health system (SUS).

through her lawyers instead. Nevertheless, the MSS decided to make the Halloween Challenge an annual event and invited any psychic in the UK to take part. When two psychics failed an experiment in October 2012, Marshall remarked: "While the result of our experiment doesn't disprove psychic ability, the fact that our mediums couldn't pass what they felt was a very fair and simple test does seem to suggest claims that these abilities exist aren't based in reality."

Engaging with "Believers"

In January 2013, Marshall and Hayley Stephens started a podcast called ''Be Reasonable'', where Marshall interviewed people with beliefs outside of science. The aim was to try to understand why people believe in these things without criticising or mocking the person being interviewed. He has stated, "...I try to avoid as much as possible talking over the details of factual claims, where I can't tell in the moment whether a fact is valid or misrepresented, but instead I try to look at the logic built around that particular fact.", " it offers a genuine reflection on how people come to any beliefs—real or false, reasonable or irrational—and how we all build our identity and our world view around our beliefs, to help us make sense of the world". Episodes of the show include interviews with

Modern belief in a flat Earth

In recent years, Marshall is reporting on the

and individuals, who promote the erroneous idea that the Earth is flat rather than a sphere, in order to understand the root of rejecting such uncontroversial facts. Marshall attended the UK's annual Flat Earth UK Convention between 27 and 29, April 2018 and noted that believers in a flat Earth vary widely in their views. While most agree upon a disc-shaped Earth, some are convinced the Earth is diamond shaped. Furthermore, while most believers do not believe in outer space and none believe mankind has ever traveled there, they vary widely in their views of the universe. To Marshall, one of the most telling moments at the convention was the "Flat Earth Addiction" test that was based on a checklist used to determine whether someone is in a

, without the convention attendees realizing the possibility of themselves being in a cult. Furthermore, Marshall points out that while the belief in a flat Earth might rightly be labelled ridiculous, it is perhaps important to approach believers in a flat Earth as much with understanding as ridicule. Namely, as Marshall states, "it is striking how many people who doubt the global model of the Earth also subscribe to all manner of other beliefs, from

During QED 2018 Marshall presented his findings from the Flat Earth Convention to the skeptic community, during an interview with Alex Moshakis, of The Observer, before the talk he said ''"his intention was not to pillory Flat Earth beliefs, but to explain what might turn a person against conventional science, and how their beliefs can become contagious."''
