Economic research determines economic policy, which determines economic politics" could be a summary of the basic philosophy of the World Complexity Science Academy (WCSA) applied to the field of economics. Such an evidence-based policy is lively in academic circles but still absent in the political world. However, there is more: looking back in order to extrapolate and forecast tendencies for the future, as the evidence-based policy does, needs to be complemented by forward-looking attempting to identify megatrends based on change drivers that should be translated into concrete policy action today. Therefore, to narrow the gap between economy, policy and politics, foresight thinking on top of evidence-based policy could be the best option for more accurate policy and law-making. Black boxes should be avoided in the evidence-based approach as it makes policy unexplainable to the citizens and politicians unaccountable. Black swans could be integrated into the foresight-based advice in an attempt to foresee the unforeseeable and think the unthinkable.
