An algorithm is a step-wise procedure for solving a specific problem in a finite number of steps. The result (output) of an algorithm is predictable and reproducible given the same parameters (input). A heuristic is an educated guess which serves as a guide for subsequent explorations.

What are algorithms and heuristics in psychology?

In psychology, algorithms are frequently contrasted with heuristics. A heuristic is a mental shortcut that allows people to quickly make judgments and solve problems. ... If complete accuracy is required, it is best to use an algorithm. By using an algorithm, accuracy is increased and potential mistakes are minimized.

Why do people use heuristics instead of algorithms?

An Algorithm is a clearly defined set of instructions to solve a problem, Heuristics involve utilising an approach of learning and discovery to reach a solution. So, if you know how to solve a problem then use an algorithm. If you need to develop a solution then it's heuristics.
