Ready Research (formerly READI) is a group of volunteers who conduct research and provide evidence-informed, rigorous and implementable recommendations for practitioners working on significant societal problems. As a research collaboration, we - identify research areas where behaviour change or improved decision-making would do the most good - coordinate and conduct rigorous applied research to discover how to change behaviour or improve decision-making, and - amplify the reach and impact of behavioural evidence so that it can help support doing the most good with what we have. If you're trying to decide which messaging will best encourage prospective donors to contribute financially to your charity, then you should read about our charitable donations review. If you’re working in animal welfare or trying to encourage the public to eat less meat and other animal products, then you should read our animal products consumption review preprint.If you’re trying to decide on the policies that will most reduce harm and support a sustainable recovery from COVID-19, you should read about our Survey of COVID-19 Responses to Understand Behaviour (SCRUB) project.
