On Tuesday November 1st a meeting organised by Sense About Science was held in the Speaker’s room in the UK Parliament. It was attended by MPs, civil servants and 100 members of the public. The purpose of the event – ‘Evidence Matters’ – was to promote the importance of evidence to people across all walks of life. Sense About Science put out a call for stories of the importance of evidence, and collated them into a booklet that was handed out at the meeting.
