The Seven Types of Knowledge Claims in the Social Sciences

Summary

The speaker explains how knowledge is formed and assessed, emphasizing that scientific conclusions are not treated as permanently indisputable facts. Scientific progress occurs when observations challenge existing hypotheses, prompting researchers to test and sometimes reject them. Because evidence can be disputed, science also has a social dimension: researchers evaluate one another’s claims, including through peer review.

The study of knowledge and how we know what we know is called epistemology. The speaker outlines seven ways people make knowledge claims:

1. Tradition — Beliefs accepted because they have been passed down through families, communities, or religions and have remained largely unchallenged. An example is a child-rearing practice inherited from one’s parents.
2. Intuition — A sense or feeling that something is right or wrong, without a clearly identified appeal to evidence. People may rely on intuition in everyday choices, such as deciding what to eat or what gift to buy.
3. Authority — Accepting a claim because it comes from someone regarded as influential or knowledgeable, such as a scientist, professor, doctor, or political leader. This involves trusting that person’s judgment rather than examining the evidence directly.
4. Personal experience — Drawing conclusions from what one has experienced before. For instance, someone might prefer a particular food because it has been a favorite in the past. This differs from intuition because it rests on prior encounters.
5. Reasoning — Reaching conclusions through logic. For example, one might decide to take an umbrella when rain is forecast, based on the expectation that being in the rain without one would be uncomfortable.
6. Empiricism — Relying on direct observation through the senses, such as seeing, hearing, or feeling something. People may observe the same thing but judge it differently—for example, hearing the same music and finding it either beautiful or dull.
7. Scientific method — The most systematic and rigorous approach in the speaker’s account. It combines empirical observation with reasoning to develop and test hypotheses, assess evidence, and build a broader body of knowledge.

How the Scientific Method Is Presented

The process involves:

• Beginning with a question or possible explanation.
• Considering what aspects of the subject can be observed.
• Forming a hypothesis that can be examined.
• Using reasoning to work out how the hypothesis might be tested.
• Gathering observations or other empirical evidence.
• Evaluating whether the evidence supports or challenges the hypothesis.
• Revising or rejecting the hypothesis when warranted.
• Continuing to test and connecting findings into a larger body of evidence and knowledge.
• Subjecting scientific claims to evaluation by other researchers, including through peer review.

The speaker’s overall point is that people use many kinds of knowledge in everyday life, but scientific inquiry aims to make claims more systematic by combining observation, logic, testing, and collective evaluation.
