When do I use "Refute" and when do I use "Rebut"?

"Refute" = to definitively prove something false (requires conclusive evidence). "Rebut" = to counter-argue or respond (does not require proving anything definitively).

What is the most common mistake with "Refute" and "Rebut"?

The most common error in journalism: "The minister refuted the allegations" when they only denied or responded without proving them false. "Refute" implies total intellectual victory with conclusive evidence; "rebut" only implies a response or counter-argument.

How do I remember the difference between "Refute" and "Rebut"?

REBUT contains "BUT": "yes, BUT here is my counter-argument" (no proof required). REFUTE contains "FUT" (future), after a true refutation, the claim has no future; it is definitively disproved with evidence.

Did you know?

The REFUTE/REBUT confusion in journalism is so widespread that some descriptive dictionaries (which record actual usage, not prescriptive rules) now accept REFUTE in the sense of "deny or question" without proof. However, in formal logic, philosophy, and academic writing, the distinction remains essential: a "refutation" without proof is not a refutation, it is a denial. Karl Popper based his philosophy of science on "falsifiability", the idea that a scientific claim must be REFUTABLE (able to be proved false with evidence). If something cannot in principle be refuted, it is not science but metaphysics. The word REFUTE is therefore at the heart of the scientific method.
