An interesting paper on Housing First;
Only with analyses that can look broadly at homelessness, not just by group, and its impacts across service sectors and broader society will we have better understanding of the implications homelessness has for society. Even by increasing the scope of our research, while providing valuable insights into the nature of the problem, this evidence cannot determine the complex, contextual and ultimate value based decision making that should be a part of the democratic policy process.In terms of the political arena, John Maynard Keynes once said “there is nothing a politician likes so little as to be well informed; it makes decision-making so complex and difficult”. Evidence based policy may, in fact, be a strategy to simplify decision-making, but the result is that politicians are not well-informed in the broader sense. Whereas, by being informed by a democratic process and from an inclusive knowledge base, policy makers can then genuinely grapple with decisions that are about sharing limited resources and improving the human condition which are, and always will be, complex and difficult.
