Evidence is essential stuff. It is objective. It answers questions and helps us to solve problems. It helps us to predict. It puts decisions on the right track. Evidence makes sure that decisions are safer. Evidence can turn guesswork into certainty. Evidence tells us what works. It explains why people think and act as they do. It alerts us to likely consequences and implications. It shows us where and when to intervene. We have robust methods for using evidence. Evidence is information; information is abundant. It is the most reliable basis for making policy. Evidence is the most reliable basis for improving practice. There has never been a better time for getting hold of evidence.
