Abductive Reasoning
The Basic Idea
The scientific method begins with a hypothesis—an educated guess. After making some sort of observation about the world, scientists come up with a potential explanation, which they put to the test using cleverly-designed experiments. But until there’s data to back them up, hypotheses are just stabs in the dark: they might be accurate, but they also might not be.
The generation of hypotheses relies on a particular kind of logical inference, known as abductive reasoning, abduction, “inference to the best explanation,” or, simply, “hypothesis.” Alongside its sisters, deductive (“top-down”) reasoning and inductive (“bottom-up”) reasoning, abductive reasoning is a core component of the methodology of science, and although it cannot itself be the basis for any sort of conclusions about the world, it represents the crucial first step towards that end.
Abduction is the process of forming explanatory hypotheses. It is the only logical operation which introduces any new idea..
