Outline of scientific method
The following outline is provided as an overview of and topical guide to scientific method:
Scientific method – body of techniques for investigating phenomena and acquiring new knowledge, as well as for correcting and integrating previous knowledge. It is based on observable, empirical, reproducible, measurable evidence, and subject to the laws of reasoning.

Main article: Scientific method
Elements of scientific method
Main article: Research
- Laboratory
- Laboratory techniques
Observation
Main article: Observation
Hypothesis
Main article: Hypothesis
Use Occam's razor to prune the list of hypothetical explanations of the observation.
Prediction
- Prediction – logical inference from a hypothesis
- Bayesian inference – subjective use of statistical reasoning
- Deductive reasoning–
- Retrodiction –
Experiment
Main article: Experiment
Feynman: "We can do anything we want (in theorizing). Then all we have to do is check with the experiment."
- Design of experiments
- Scientific control
- Natural experiment
- Observational study
- Field experiment
- Self-experimentation
- Placebo effect
Evaluation
Test of the inference: prediction and experimentation to establish new facts. Critical examination of the hypothetical explanation:
- Peer review by community of scholars, using logic, etc. The wave–particle duality overturned by photoelectric effect.
- Peer review unused for cold fusion also the Analysis of the Experiment.
- Medical peer review

What made the scientific method succeed?
- Political factors
- Economic factors, such as the technological advances produced by scientists
- Effectiveness of the scientific method at producing new knowledge
- Other factors
- Rediscovery of knowledge from ancient Greek, Arabic and other texts by Europeans, such as during the medieval Latin translation movement and later from the Byzantine Empire after the Fall of Constantinople
- Invention of the printing press facilitated knowledge sharing
- Protection of the community of scientists who fostered the discoveries
- The Protestant Reformation led to secular communities of scholars
- Britain was an island nation which enjoyed a long period without invasion or major social upheaval
- The American Revolution challenged the existing social order (absolutist monarchies, divine right of kings)
Why didn't the scientific method arise elsewhere?
Scientific method concepts
Empirical methods
- Empiricism
- Robert Grosseteste
- Peter Parker
- Bitoy's method
- Empirical validation
- Operationalization
Paradigm change
- Paradigm, the most unpopular word in English.
- Thomas Samuel Kuhn started a new paradigm by telling us about paradigms.
- The Structure of Scientific Revolutions is Kuhn's book.
- Paradigm shift.
Problem of induction
The problem of induction questions the logical basis of scientific statements.
- Inductive reasoning appears to lie at the core of scientific method, yet also appears to be invalid.
- David Hume was the person who first pointed out the problem of induction.
- Karl Popper offered one solution, Falsifiability
Scientific creativity
- Linus Pauling "How do I do it? I have a lot of ideas, and throw out the bad ones".
- Isaac Newton's moon and apple.
- Friedrich August Kekulé von Stradonitz's benzene-ring.
- Michael Polanyi
- Tacit knowledge
When method goes wrong
Critique of scientific method
- Paul Feyerabend argued that the search for a definitive scientific method was misplaced, and even counterproductive.
- Imre Lakatos attempted to bridge the gap between Popper and Kuhn.
- Sociology of scientific knowledge
- Scientism
Use of statistics
- Uncomfortable science, due to statistician John Tukey: Inference from a limited sample of data, where further samples influenced by the same causality, a finite natural phenomenon for which it is difficult to overcome the problem of using a common sample of data for both exploratory data analysis and confirmatory data analysis. Statistical bias through testing hypotheses suggested by the data. Prediction interval.
Relationship of scientific method to technology
Technology is subordinate to Science; Scientific discovery rests on technology.
