The findings of natural scientists being built on less competing paradigms are more often used for showcasing the need to policy action. When it comes to economics, or social sciences—their role is bigger in providing policy options or approaches which may contribute to finding solutions to policy challenges. The practitioners, policy-makers and scientists who share these views form communities, while between them different world views are competing, creating competing scientific evidences and competing assessments. This competition is often preferable to policy-makers. When it is about communicating decisions to politicians, civil society or the general public, it is also important for policy-makers to incorporate different world views to fit different opinions. The English language is very favourable for this discussion—there is a distinction between "policy" and "politics". Some institutions, such as scientific councils act as an interface between science and policy by producing reports of the state-of-the-art scientific knowledge on any topic.
