Study Notes
The Limitations of the Scientific Method
- The traditional textbook model of the scientific method is flawed and doesn't accurately represent how science is done.
- The textbook model involves developing hypotheses, deducing their consequences, and testing them in the natural world.
Problems with the Textbook Model
- The problem of the fallacy of affirming the consequent: false theories can make true predictions, so a correct prediction doesn't necessarily prove a theory is correct.
- Example: the Ptolemaic universe model made accurate predictions, but was later proven incorrect.
- The problem of auxiliary hypotheses: scientists make assumptions that may or may not be aware of, which can affect the outcome of experiments.
- Example: astronomers made incorrect assumptions about the size of the Earth's orbit and the sensitivity of telescopes, affecting their ability to detect the stellar parallax.
Inductive vs. Deductive Science
- A lot of science doesn't fit the traditional textbook model; instead, scientists often start with observations and work backwards to develop theories.
- Example: Charles Darwin's work, which was based on detailed observations of the natural world rather than a preconceived hypothesis.
The History of Science
- Albert Einstein's theory of general relativity predicted that light would bend around massive objects like the sun, but this is not a direct proof of the theory's correctness.
- The Ptolemaic universe model was widely accepted for centuries despite being incorrect, highlighting the limitations of the textbook model.
