falsifiable
fall-sih-FY-uh-bul
/ˌfɔːl.sɪˈfaɪ.ə.bəl/
Capable of being tested and potentially proven false by observational or experimental evidence.
Does not mean a statement is false, but rather that it makes specific predictions that could be disproven if the data contradicts them.
The story behind the word. Formed from Latin 'falsus' (deceptive, erroneous) combined with '-ficare' (from 'facere', to make). Austrian philosopher Karl Popper introduced the falsifiability standard in the 1930s. He argued that no number of white swan observations can permanently prove 'all swans are white', but observing a single black swan immediately falsifies it. Thus, scientific progress proceeds by trying to disprove hypotheses.
Word relationships
- refutable: Refutable means able to be disproved; falsifiable specifically carries the methodological standard required for empirical testing.
- testable: Testable is a broader term meaning open to trial, whereas falsifiable highlights the explicit condition that failure must remain a theoretical possibility.
- unfalsifiable: Unfalsifiable means immune to empirical testing because no possible observational outcome can disprove it.
Commonly confused with
- fraudulent: Fraudulent implies intentional deception, whereas falsifiable describes a standard of scientific rigor.
Word family
- falsify (verb): To prove a theory or claim to be false.
- falsifiability (noun): The capacity of a hypothesis to be disproven by experiment.
Collocations
- falsifiable claim
- falsifiable hypothesis
- strictly falsifiable
- falsifiable criterion
Example sentences
- "Karl Popper argued that for a theory to be genuinely scientific, its claims must be strictly falsifiable." Philosophy of science
- "Critics questioned whether string theory should be classified as empirical science if none of its core claims are currently falsifiable." Scientific debate
Memory hook
A claim is FALSIFIABLE if an experiment could show it FALLS down in failure. Testable because it can theoretically be proven false.
When not to use
Do not confuse with 'false' or 'fraudulent'; a falsifiable claim is often true, but scientifically valid because it risks being tested.
Fun facts
- Popper created the criterion of falsifiability specifically to explain why Einstein's physics was scientific while astrology and psychoanalysis were not.
