Discipline: Philosophy

Somewhat bizarre name occasionally given to the view that the scientist should look for the most improbable hypothesis, because it will be the easiest to refute, if false, but the most significant to accept if it survives testing.

Improbabilism is associated especially with Karl Raimund Popper (1902-1994).

For him, the only way a hypothesis can be 'probable' is by saying comparatively little, and so hedging itself against refutation.
