How neoteny shapes human society: Can we escape our formative years, and fight the wrong kind of populism?

This article describes aspects of our biological nature that have contributed to the dangerous current state of societal, ecological and climatological affairs. Next, it deals with stratagems to take these aspects into account, so as to allow us better choices. I will concentrate on the concepts of evolved group mechanisms and "neoteny" and explain why they direct our responses throughout our lives. The connection between our biological make-up and our vulnerability to the current rise of certain kinds of irrational, undemocratic, populism is also laid bare. I will end by listing some simple, but possibly controversial, proposals that might have value in combating these societal tendencies and help decision making in a reality-based, more scientific, manner.
