Heuristic argument

A heuristic argument is an argument that reasons from the value of a method or principle that has been shown by experimental (especially trial-and-error) investigation to be a useful aid in learning, discovery and problem-solving. A widely used and important example of a heuristic argument is Occam's Razor.

It is a speculative, non-rigorous argument, that relies on an analogy or on intuition, that allows one to achieve a result or approximation to be checked later with more rigor; otherwise the results are of doubt. It is used as a hypothesis or conjecture in an investigation. It can also be used as a mnemonic.^[1]
