Historical evidence supports the predictions generated by the model. In underdeveloped countries we are faced with the vicious circle of high fertility, with resulting population growth and economic stagnation. The cultural background of this economic situation is marked by the low status of women, usually sanctioned by major world religions, which enjoy women's enthusiastic support. Religion is often described as a major obstacle to family planning and all other changes in women's status, which are the key to lowering fertility. Economic growth, education, and birth control are all interconnected, and they are all tied to secularization.
Education seems the surest way, guaranteed to reduce fertility in most developing societies.
But on this basis, ethics is able to pass value judgements on the preferability of interaction in every sphere of any given ethos by religion or Weltanschauung . On the contrary, it guides observation and theory-building. It is gained through reflection on the universal traits of the conditio humana. Thus, in short, ethics is the conceptual meta-theory of interactional life in general. To analyse the cognitive and emotional problems connected with religions the idea of pure religion is elucidated, which has been used to immunise religious views against scientific criticisms.
