Psychology is an integral part of our modern society and its influence is quite widespread. Many important decisions made in our society can be based on psychology, decisions that affect the lives of many people. This is why it is important to determine whether psychology is a science or not. The answer to the question of whether psychology is a science is not a simple “yes” or “no”: it depends on the area of ​​psychological study, the theory used within an area, and often how the researcher chooses to study a topic. phenomenon (Makunda, 1997). It also depends on what you mean by “scientific” – for the philosopher of science Karl Popper, for example, the most important criterion was what he called “falsifiable”. There are also other scientific criteria, which I will present in this essay. I will examine different psychological theories in light of different aspects of scientific activity. Defining science is no easy task. There are many different concepts of science. According to Webster (1992) science is the observation, identification, description, experimental investigation and theoretical explanation of phenomena, through objective means. Simply put, scientists conduct experiments and observations to gather data about the world and to explain these facts. Chalmers (1999) states that science is something visible, tangible, audible, rather than opinions or beliefs. Davies states that: “Science is a fact-based structure” (as cited in Chalmers, 1999, p. 1). The American Heritage Science Dictionary seems to understand the general consensus and defines science as: “The investigation of natural phenomena through observation, theoretical explanation, and experimentation, or knowledge produced… in the middle of the paper…”. .aim at scientific principles to measure the entire world. In many areas of psychology there is no attempt to generalize from some human behaviors to all human behaviors. It might be a more useful exercise to divide psychology into its separate fields and ask questions of each. It could be argued that the behaviorist approach is the most scientific, as it focuses on what people do, rather than how they think; something that is observable. The approach ignores speculation with an emphasis on objectivity. In contrast, most of Freud's theories within the psychodynamic approach seem untestable, unfalsifiable, and ultimately unscientific. The question and answer sessions associated with psychoanalysis are based on introspection, of which there are scientific doubts. What is certain is that the debate over psychology as a science is likely to remain a debate for some time.
