Welcome to Good Thinking

Our goal is “to encourage curiosity and promote rational thinking”, hence the positive title of the organisation. At the same time, this inevitably means battling against irrationality and pseudoscience. We are pro-science and pro-evidence, which means we are anti-woo and anti-quack. In short, we like skepticism, but not cynicism. We like nerds and geeks, but we hate bogus things without a jot of evidence.

Despite being a relatively-young charity, our work has taken many forms, including encouraging excellence in the teaching of maths, successfully challenging NHS spending on homeopathy, sponsoring awards for science blogging, organising awareness-raising campaigns about the nature of psychic claims, screening a documentary about James Randi & skepticisminvestigating and reporting dangerous alternative health treatments, publishing factsheets on common pseudosciences, and more.

Over the coming years, we hope Good Thinking will sit alongside all the other excellent initiatives in UK skepticism, such as the Skeptics in the Pub network and QEDcon. Follow us on twitter @GoodThinkingSoc for news of activities, or use the sign-up form to subscribe to our newsletter.

Good Thinking is a Registered Charity No.1147404


The Good Thinking Society is a small charity that is pro-science and anti-pseudoscience. Some of our recent projects have been linked to education in schools, particularly supporting mathematics. These projects have been seeking funds from a range of organisation that support STEM education, but Good Thinking’s other projects are largely funded by donations from its founder, Simon Singh.

He will continue to fund Good Thinking with further donations and by offering to speak at fundraising events for any institution interested in lectures on cryptography, alternative medicine, The Simpsons & Their Mathematical Secrets, cosmology, Fermat’s Last Theorem and science in the media. The goal was to raise £20,000 at ten such events in 2014 and 2015. So far, Simon has raised over £23,000 through his lectures – thanks to everyone who has supported Good Thinking in this way. If you want to donate to Good Thinking by booking a talk from Simon, you can find out more and get in touch with us.

Good Thinking is particularly grateful for a donation of almost £7,000 from QEDcon. We are also grateful to those individuals who have supported us by donating thousands of pounds every year to support our work. Find out how you can join them by making a one-off or monthly donation to help support our work.

One of the big strengths of the skeptical community is the breadth of talents, backgrounds, skills and passions we encompass.
