Michael Marshall is a British skeptical activist, freelance journalist, public speaker, podcaster, author and blogger. He is co-founder and vice-president of the Merseyside Skeptics Society and co-host of its official podcast Skeptics with a K, project director of the Good Thinking Society, and has occasionally written for The Times, The Guardian and New Statesman.
Marshall obtained a BA in English in Liverpool, and has worked there in marketing and web design since. In February 2009, Marshall, Mike Hall and Colin Harris founded the Merseyside Skeptics Society, a non-profit organisation which aims to develop and support the skeptical community on Merseyside. The society holds regular events in Liverpool City Centre and it also publishes three podcasts (Skeptics with a K, InKredulous and Be Reasonable), is behind the 10:23 Campaign (aimed at raising public awareness of homeopathy – resulting in international coverage and worldwide skeptical involvement), and, together with the Greater Manchester Skeptics, organises the QED (Question, Explore, Discover) conference.
Since March 2014, Marshall has been project director at the Good Thinking Society (GTS). Their goal is to encourage curiosity and promote rational thinking, battling against irrationality and pseudoscience by being pro-science and pro-evidence.
With a background in marketing and communications, his skeptical activism has included testing psychic claims, trialling sports performance wristbands, interviewing proponents of alternative beliefs and exposing the influences of PR in journalism.
