Which problem-solving method involves testing various solutions until one is found that works?

The method that involves testing various solutions until a successful one is found is known as trial and error. This approach is characterized by trying out different possibilities and learning from mistakes or failures after each attempt. It is particularly useful in situations where there is no clear strategy or solution available, allowing the problem-solver to explore multiple avenues until the right one is discovered. This method is often employed in practical tasks, such as trying different combinations to open a lock or figuring out how to assemble furniture without clear instructions.

In contrast, intuition relies on instinctive feelings or gut reactions rather than systematic problem-solving. An algorithm is a step-by-step procedure that guarantees a solution if followed correctly but does not involve testing multiple options independently. Cognitive biases refer to the systematic patterns of deviation from norm or rationality in judgment, which can cloud decision-making but do not specifically address a method for solving problems through trial and error.
