Adopting evidence-based practice (EBP) has the potential to significantly improve policy outcomes, contribute to homelessness reduction and enhance societal wellbeing. But we know adopting EBP is not easy. It requires us to be sceptical, to question our knowledge and beliefs, to identify the key questions and not be afraid to admit we don’t have all the answers. It also requires placing as much importance in evidence as in the knowledge and experience of professionals and the value and preferences of those affected by, or at risk of, homelessness.
