Popper vs. Kuhn: Philosophy of Science and Paradigm Shifts
Differences Between Verificationism and Falsificationism
The two major approaches to scientific methodology are:
- Verificationism: An increased number of confirming cases suggests the hypothesis is true and possesses greater scientific value.
- Falsificationism: A hypothesis is only important if it is deemed unlikely to happen and is capable of being proven false.
Critiques of Falsificationism
