- In scientific reasoning, a hypothesis is constructed before any applicable research has been done. A theory, on the other hand, is supported by evidence: it’s a principle formed as an attempt to explain things that have already been substantiated by data. (Hypothesis- An idea that has been tested many, many times, pretty much works, still has some issues that might be worked out.) (Theory- The BEST explanation of the facts so far. Predictable. Testable. Most scientist agree that it is probably right.)
