Our campaigns call for open discussion about evidence, free from intimidation, hysteria and political pressure 

Sense About Science has never lost a campaign it’s taken on” - Ben Goldacre

Don’t leave this page without changing something:

Ask for Evidence is a public campaign that helps people request for themselves the evidence behind news stories, marketing claims and policies. We hear daily claims about what is good for our health, bad for the environment, how to improve education, cut crime, treat disease or improve agriculture. Some are based on reliable evidence and scientific rigour. Many are not. #AskforEvidence today


The AllTrials campaign calls for every clinical trial, past and present, to be registered and their results reported.  Only around half of all clinical trials ever conducted have reported results, and thousands more have never even been registered. Information on what was done and what was found in these trials could be lost forever - leading to bad treatment decisions, missed opportunities for new medicine, and trials being needlessly repeated.  Support the global effort to get all clinical trial results reported. Without improved transparency vital information could be lost to medicine forever. Sign the AllTrials petition

Sense About Science launched the Keep Libel Laws out of Science campaign in June 2009, calling for reform of the libel laws to protect open scientific discussion. We then formed the Libel Reform Campaign in partnership with English PEN and Index on Censorship. We have been successful in reforming the libel laws in England and Wales – but there’s more to do. To support the expansion of the campaign to Northern Ireland and other efforts worldwide, get involved at



The impact of our campaigns

Some of our recent achievements include:

  • Thanks to the support of 86,000 people and 620 organisations, the AllTrials campaign has put transparency at the heart of new clinical trial law in Europe from 2016
  • With the support of 60,000 people, 60 civic society organisations and our partners English PEN and Index on Censorship, our Libel Reform campaign convinced the English and Welsh Governments to adopt the Defamation Act 2013
  • Sense About Science played a leading role in campaigning for the Government to include principles for the treatment of independent advice into the Minsterial Code in 2010
  • Young researchers from our Voice of Young Science programme worked with medics in Africa to persuade the WHO to condemn the promotion of homeopathy for serious diseases in the developing world for the first time
  • Sense About Science played a key role in persuading the EU to repeal the Physical Agents Directive which threatened research using MRI in 2008 – the first time an EU Directive has ever been repealed
  • With the help of leading neuroscientists and scientific bodies we raised awareness among local authorities and teachers about the lack of evidence for Brain Gym leading to many schools dropping the programme
