Science knowledge indicates what can happen in natural systems not what should happen. Explain this statement and provide an example

Science knowledge indicates what can happen in natural systems not what should happen because scientific knowledge give us a way in which things are done but sometimes it did not happen at that way.

Explanation:

Scientific knowledge cannot be used in all aspects of life such as politic, social and culture. In some matters, decisions were made not through scientific knowledge but by using the laws or principles of culture and society. Scientific knowledge give the possibility that an event can happen but sometimes we solve the problem according to the culture and laws of society.
