Facts about the Scientific Method
- 08
Thomas Kuhn's 1962 book The Structure of Scientific Revolutions introduced paradigm shifts, showing that scientific progress occurs through revolutionary changes in fundamental assumptions rather than purely incremental advancement.
- 07
Occam's Razor, formalized by William of Ockham in the 14th century, established that simpler explanations requiring fewer assumptions are preferable in scientific method applications, influencing hypothesis selection for centuries.
- 06
Controlled variables, systematically isolated during experiments since the 1700s, became crucial to the scientific method by allowing researchers to determine cause-and-effect relationships rather than mere correlations.
- 05
Reproducibility, requiring independent researchers to obtain identical results using the same methods, became a cornerstone of the scientific method by the late 1800s to distinguish legitimate science from fraud.
- 04
Double-blind experiments, where neither researchers nor subjects know who receives treatment versus placebo, became standard practice in the 20th century to eliminate observer bias in scientific method applications.
- 03
Peer review, formalized in the 1665 founding of the Journal des Sçavans, became essential to the scientific method by requiring independent verification before publication.
- 02
Karl Popper's 1934 falsifiability principle established that a hypothesis must be testable and potentially disprovable to qualify as scientific, fundamentally reshaping methodology standards.
- 01
In 1620, Francis Bacon formalized the scientific method by introducing systematic observation and experimentation, moving away from purely theoretical Aristotelian approaches.
