What is the process by which social scientists evaluate ideas and theories through systematic analysis?

Answer: Scientific Method

Explanation: The scientific method is used across many fields of study to make observations, evaluate ideas and postulate theories. It is the way scientists establish a fact. The aim of the scientific method is to differentiate facts from opinions or gut instinct such that a fact is true universally. To do this, an observation goes through several processes and may be proven by several experiments, and peer reviews before it can be declared a fact.
