Failure is the social concept of not meeting a desirable or intended objective, and is usually viewed as the opposite of success.
Finding useful and effective criteria or heuristics to judge the success or failure of a situation may itself be a significant task.

Most of the items listed below had high expectations, significant financial investments, and/or widespread publicity, but fell far short of success.
Wan and Chan note that outcome and process failures are associated with different kinds of detrimental effects to the consumer.

This failure to confirm the presence of the aether would later provide support for Albert Einstein's special theory of relativity.
