Quotes About Heuristics

You see the shadow. Snap! You are frightened—and running. That's the "availability heuristic," one of many System 1 operations—or heuristics—discovered by Daniel Kahneman, his collaborator Amos Tversky, and other researchers in the fast-growing science of judgment and choice.

Life is full of signs. The trick is to know how to read them. Ghosh called this heuristics, a method for solving a problem for which no formula exists.

Fast thinking includes both variants of intuitive thought—the expert and the heuristic

The question that the executive faced (should I invest in Ford stock?) was difficult, but the answer to an easier and related question (do I like Ford cars?) came readily to his mind and determined his choice. This is the essence of intuitive heuristics: when faced with a difficult question, we often answer an easier one instead, usually without noticing the substitution.

The spontaneous search for an intuitive solution sometimes fails—neither an expert solution nor a heuristic answer comes to mind. In such cases we often find ourselves switching to a slower, more deliberate and effortful form of thinking. This is the slow thinking of the title. Fast thinking includes both variants of intuitive

The availability heuristic, like other heuristics of judgment, substitutes one question for another: you wish to estimate the size of a category or the frequency of an event, but you report an impression of the ease with which instances come to mind. Substitution of questions inevitably produces systematic errors.

the accurate intuitions of experts are better explained by the effects of prolonged practice than by heuristics.

people rely on a limited number of heuristic principles which reduce the complex tasks of assessing probabilities and predicting values to simpler judgmental operations. In general, these heuristics are quite useful, but sometimes they lead to severe and systematic errors.

The executive's decision would today be described as an example of the affect heuristic, where judgments and decisions are guided directly by feelings of liking and disliking, with little deliberation or reasoning.

Part 2 updates the study of judgment heuristics and explores a major puzzle: Why is it so difficult for us to think statistically? We easily think associatively, we think metaphorically, we think causally, but statistics requires thinking about many things at once, which is something that System 1 is not designed to do.

In particular, the accurate intuitions of experts are better explained by the effects of prolonged practice than by heuristics. We can now draw a richer and more balanced picture, in which skill and heuristics are alternative sources of intuitive judgments and choices.

Moreover, one must show, in the historical period of interest, that these heuristics and preferences are consistent across a significant portion of decision makers socialized in this strategic culture before drawing any conclusions about

By their very nature, heuristic shortcuts will produce biases, and that is true for both humans and artificial intelligence, but the heuristics of AI are not necessarily the human ones.

Humans have limited time and brainpower. As a result, they use simple rules of thumb—heuristics—to help them make judgments.

Authentic humans don't show the perfect, chessmaster appreciation of consequences that von Neumann's theory demands. Instead, decision makers resort to heuristics, or mental shortcuts, to arrive at quick, intuitive choices.

Clean code is not written by following a set of rules. You don't become a software craftsman by learning a list of heuristics. Professionalism and craftsmanship come from values that drive disciplines.

There are two parts to learning craftsmanship: knowledge and work. You must gain the knowledge of principles, patterns, practices, and heuristics that a craftsman knows, and you must also grind that knowledge into your fingers, eyes, and gut by working hard and practicing.

While there have been terrific advances in the state of technology around heuristics, behavior blocking, and things like that, technology is only a part of the approach to solving the problem with the more important aspect involving putting the right process in place.

The test conditions that are chosen will depend on the test strategy or detailed test approach. For example, they might be based on risk, models of the system, likely failures, compliance requirements, expert advice or heuristics. The word 'heuristic' comes from the same Greek root as eureka, which means 'I find'. A heuristic is a way of directing your attention, a common sense rule useful in solving a problem.

In an entry from late 1979, Dick writes Heuristics is right on. The closer you get to reality the closer you get to (and to seeing) process. Q isn't "what is (esse)?" but "What does?" […] replace each "is" with "does" and ontology vanishes. All you have is a perpetually perturbed reality field! With a self-producing vortex.12

The concept of modularity is related to information hiding, encapsulation, and other design heuristics. But sometimes thinking about how to assemble a system from a set of black boxes provides insights that information hiding and encapsulation don't, so the concept is worth having in your back pocket.
