In his book “The Methodology of Social Research”, Moser argues that controlled comparison is an alternative to experimentation for some positivists. He states that “controlled comparison is a method of research which is used to investigate the causes of social phenomena by comparing the characteristics of two or more groups of people who differ in one respect but are similar in other respects.”
Moser argues that controlled comparison is a valuable tool for positivists because it allows them to investigate the causes of social phenomena without having to manipulate the independent variable. He states that “controlled comparison is a powerful tool for investigating the causes of social phenomena because it allows the researcher to control for other variables that might be affecting the dependent variable.”
Moser’s argument has been influential in the field of social research. His work has helped to shape the way that positivists think about the causes of social phenomena.
