Chapter 6: Developing hypotheses

‘Karl Popper’s Falsification’

Question 1: What was Karl Popper’s key argument about scientific hypotheses?

Answer 1: That they were falsifiable; that they could be tested through observation.

Question 2: Why did Popper not like Marxism?

Answer 2: Because Marxists claimed their theories were a ‘scientific’ analysis of history, but Marxists theories and explanations for the course of history could not be tested and thus falsified. Therefore, they were not scientific.

Question 1: How did Karl Popper distinguish between the science Einstein was conducting and the science Freud was conducting?

Answer 1: Popper argued that Einstein was conducting ‘real science’ where he was developing theories and hypotheses that could be tested and falsified.

Question 2: What are the three key elements of modern scientific hypothesis or theory?

Answer 2: That they are testable, refutable and falsifiable.
