Science means traditionally, the systematic attempt to rationally categorize or explain empirical observations. Popper described science as a way of rigorously testing proposed solutions to problems, and

Kuhn emphasized the importance of paradigms that guide the research activities of scientists. Feyerabend believed it is impossible to give a generalized conception of science or scientific method.

In the context of psychology, science refers to the systematic and empirical study of behavior and mental processes. Psychology as a science aims to understand, explain and predict human behavior and mental processes by using scientific methods such as observation, experimentation, and data analysis.

Examples of the scientific methods used in psychology include:

The goal of psychological science is to create a body of knowledge that is accurate, reliable, and generalizable across individuals and contexts. By using scientific methods, psychologists are able to increase our understanding of the mind, brain and behavior and use that knowledge to improve people's lives through therapy, education, and other applications.
