What is the Difference Between Positivism and Post-Positivism?

🆚 Go to Comparative Table 🆚

The main differences between positivism and post-positivism are related to their views on objectivity, reality, and the role of the researcher. Here are the key distinctions:

  1. Objectivity: Positivists believe that objectivity is a characteristic that resides in the individual scientist, and scientists are responsible for putting aside their biases and beliefs to see the world as it 'really' is. In contrast, post-positivists argue that no individual can see the world perfectly as it is, and that all observations are theory-laden. They believe that scientists, like everyone else, are inherently biased by their cultural experiences and worldviews.
  2. Reality: Positivists assume that there is a reality independent of our thinking about it, and that equivalent laws can be revealed about the social world. Post-positivists also believe that truth should be considered objective but assert that our experiences of such truths are necessarily imperfect because they are influenced by our biases and worldviews.
  3. Role of the Researcher: Positivists view the researcher as an independent observer of the world, while post-positivists reject this idea, arguing that the researcher's identity and biases influence what they observe and conclude. Post-positivists pursue objective answers by attempting to recognize and work with such biases in the theories and knowledge that theorists develop.
  4. Methods: Positivists prefer quantitative measurement and empirical analysis to overcome individual biases of the researcher. Post-positivists, on the other hand, are more likely to use mixed methods and triangulation of quantitative and qualitative approaches, accepting the problematic nature of "objective" truths. Some post-positivists also adopt a philosophy called critical realism, which lies between positivism and interpretivism.

Comparative Table: Positivism vs Post-Positivism

The main differences between positivism and post-positivism can be summarized in the following table:

Positivism Post-Positivism
Emphasizes empiricism and objectivity Rejects positivism and presents new assumptions to unravel the truth
Believes in objective reality and that facts can be observed and measured Critiques the idea that objective reality can be observed and measured directly
Focuses on observable and measurable phenomena Accepts that not everything can be observed directly, such as human behavior, but doesn't deny the possibility of measuring abstract concepts
Assumes that scientific reasoning and common sense reasoning are the same process, with only a difference in degree Believes that scientific reasoning and common sense reasoning are essentially the same process, but with different degrees of rigor
Asserts that equivalent laws can be revealed about the social and natural worlds Rejects the idea that a researcher can be an independent observer of the social world, as the researcher's identity and perspective influence their observations
Relies on a single method of scientific inquiry Uses multiple methods of scientific inquiry, known as triangulation, to avoid errors and achieve a more accurate understanding

In summary, positivism focuses on objectivity, empiricism, and the study of observable phenomena, while post-positivism criticizes these ideas and emphasizes the importance of considering the researcher's perspective and the use of multiple research methods.
