How do pseudo-scientific hypotheses protect themselves from being testable?
Vagueness—If a statement is sufficiently vague, it will be impossible to verify or falsify it.
Ad hoc exceptions—a hypothesis that makes exceptions every time it meets counter examples.
Pseudo-science
Pseudo-science is fake science.
What distinguishes a pseudo-science is that it claims the status of science while lacking its substance.
Scientific method
Also known as Inductivism. What distinguishes science from non-science is a distinctive method.
Controllability
Varying only one factor at a time to determine its effect.
Measurability
Measuring the relevant variables. This adds precision and objectivity to the experiment.
Repeatability
The ability for others to repeat the experiment and confirm the results. This ensures objectivity.
Observation
Making observations and recording data during an experiment.
Problems with observation
Selectivity
Expectations
Expert seeing
The observer effect
Hypothesis
An idea or guess that tries to explain the observations.
Problems with hypothesis
Confirmation bias
Background assumptions
Argumentum ad ignorantiam
Under-determination
Prediction
How a phenomenon should “act” according to the hypothesis.
Law
A statement based on repeated experimental observations that describes some aspects of the universe
However, there is the problem of induction.
Theory
Explains and unifies various laws in terms of some underlying principles. A good theory explains why the laws are the way they are and provides a focus for further research.
Confirmation bias
People tend to look for evidence that confirms their beliefs and overlook evidence that goes against them.
Falsification
A theory that explains everything explains nothing.
According to Popper, there’s no such thing as a true statement, and scientists should spend their time trying to prove their hypotheses are false.
Any theory that resists our best efforts to falsify it should be provisionally accepted as the best we have for the time being.
