Highlights
The video begins by defining science as derived from the Latin word 'scientia,' meaning knowledge, and research as the production of new knowledge using scientific methods. It introduces the concept of the philosophy of science as the study of the foundations, methods, and implications of scientific knowledge, encompassing ontology (what is science), epistemology (how to build scientific knowledge), and implications (how scientific knowledge works in the real world).
The video outlines four major philosophical stances in research: positivism, constructivism (also known as interpretivism or constructionism), critical realism, and pragmatism. Each of these stances offers a different approach to understanding truth and conducting scientific inquiry.
Positivism is presented as the belief in a single objective truth, emphasizing rigor, replicability, reliability, and generalizability in research. Positivists often use deductive reasoning and favor experiments to test cause-and-effect relationships through manipulation and observation. They value knowledge that can be directly observed and objectively measured, dismissing subjective experiences like emotions as not being knowledge.
Constructivism offers a contrasting view, asserting that the world is mentally constructed and truth can vary by context and human observation. Constructivists are interested in how people's views are shaped by interactions and context, often employing qualitative research methods like group discussions and unstructured interviews to gather rich, contextual data, focusing on specific cases rather than generalizability.
Critical realism combines the belief in an external reality with the understanding that observations of phenomena like satisfaction or culture are subjective. Critical realists believe in an objective truth that may be difficult to reach, acknowledging that researchers are inherently biased. They advocate for data and method triangulation to reduce bias and get closer to objective truth.
Pragmatism is presented as a flexible viewpoint that doesn't adhere to a particular stance on what constitutes good research. Pragmatists prioritize the practical application and problem-solving aspects of research findings. They embrace eclecticism and pluralism, viewing current truths as tentative and subject to change over time, and believe theory should be derived from and applied back to practice effectively.
The video explains deductive reasoning, which moves from general theories to specific observations and hypothesis testing, and inductive reasoning, which moves from specific observations to general conclusions. While Karl Popper critiqued induction for its inability to definitively prove a hypothesis due to the possibility of contrary evidence (e.g., black swans), both inductive and deductive processes are recognized as essential and complementary in fundamental and applied research, often combined in abductive reasoning.
