An interesting article in The Age raises the debate about the importance of scientific thinking in all walks of life, including politics. Here is a quote from Alan Alda about the importance of questioning and evidence in science and how this could be applied to politics:
"People individually and in their national assemblies think without the use of evidence … Scientists don't do that. Scientists question their hypotheses. … They don't do that in politics – you look at the debates, they don't come anywhere near it. It's a loss. Science has so much to offer us simply in the way we make decisions and the way we think."
