Heuristic is also often used as a noun to describe a rule of thumb, procedure, or method. [99] Philosophers of science have emphasised the importance of heuristics in creative thought and the construction of scientific theories. [100]
Some heuristics have a strong underlying theory; they are either derived in a top-down manner from the theory or are arrived at based on either experimental or real world data. Others are just rules of thumb based on real-world observation or experience without even a glimpse of theory. The latter are exposed to a larger number of pitfalls.
Heuristics (from Ancient Greek εὑρίσκω, heurískō, "I find, discover") is the process by which humans use mental shortcuts to arrive at decisions. Heuristics are simple strategies that humans, animals, [1] [2] [3] organizations, [4] and even machines [5] use to quickly form judgments, make decisions, and find solutions to complex problems.
Majority heuristic (rule). This is a decision rule used in group decision making by both humans and animals, where each member of the group votes for an alternative and a decision is reached based on the option with the most votes. [ 11 ]
In statistics, the 68–95–99.7 rule, also known as the empirical rule, and sometimes abbreviated 3sr, is a shorthand used to remember the percentage of values that lie within an interval estimate in a normal distribution: approximately 68%, 95%, and 99.7% of the values lie within one, two, and three standard deviations of the mean, respectively.

Heuristic evaluation are conducted in variety of ways depending on the scope and type of project. As a general rule of thumb, there are researched frameworks involved to reduce bias and maximize findings within an evaluation. There are various pros and cons to heuristic evaluation.
A heuristic argument is an argument that reasons from the value of a method or principle that has been shown experimentally (especially through trial-and-error) to be useful or convincing in learning, discovery and problem-solving, but whose line of reasoning involves key oversimplifications that make it not entirely rigorous.
