Goldilocks Principle

The Goldilocks principle is named by analogy to the children's story "The Three Bears", in which a young girl named Goldilocks tastes three different bowls of porridge and finds she prefers porridge that is neither too hot nor too cold, but has just the right temperature.[1] The concept of "just the right amount" is easily understood and applied to a wide range of disciplines, including developmental psychology, biology,[2] astronomy, economics[3] and engineering.

Applications

  • In cognitive science and developmental psychology, the Goldilocks effect or principle refers to an infant's preference to attend to events that are neither too simple nor too complex according to their current representation of the world.[4] This effect was observed in infants, who are less likely to look away from a visual sequence when the current event is moderately probable, as measured by an idealized learning model.
  • In astrobiology, the Goldilocks zone refers to the habitable zone around a star. As Stephen Hawking put it, "like Goldilocks, the development of intelligent life requires that planetary temperatures be 'just right'".[5] The Rare Earth Hypothesis uses the Goldilocks principle in the argument that a planet must be neither too far away from nor too close to a star and galactic center to support life, while either extreme would result in a planet incapable of supporting life. In simple words, it means that the user will have the best possible option, as the device is continuously trying to find one that suits most, with least difficulties. [6] Such a planet is colloquially called a "Goldilocks Planet".[7][8] Paul Davies has argued for the extension of the principle to cover the selection of our universe from a (postulated) multiverse: "observers arise only in those universes where, like Goldilocks's porridge, things are by accident 'just right'".[9]
  • In medicine, it can refer to a drug that can hold both antagonist (inhibitory) and agonist (excitatory) properties. For example, the antipsychotic Aripiprazole causes not only antagonism of dopamine D2 receptors in areas such as the mesolimbic area of the brain (which show increased dopamine activity in psychosis) but also agonism of dopamine receptors in areas of dopamine hypoactivity, such as the mesocortical area.[]
  • In economics, a Goldilocks economy sustains moderate economic growth and low inflation, which allows a market-friendly monetary policy. A Goldilocks market occurs when the price of commodities sits between a bear market and a bull market. Goldilocks pricing is a marketing strategy that, although not directly related to the Goldilocks principle, uses product differentiation to offer three versions of a product to corner different parts of the market: a high-end version, a middle version, and a low-end version.
  • In business, the Goldilocks Principle describes for what quantities one should create or sell products. It states that one should always create/sell a product in at least large, medium, and small sizes. This will cover the widest range of people who want the product.[10]
  • In marketing, the Goldilocks Effect/Principle/Theory is to offer versions of a product at high, mid, and low prices to encourage the buyer to purchase the mid-priced product rather than a cheaper product. [11]
  • In software development, the Goldilocks Principle describes how many features one should include in the software product. It states that one should always create a product with a slimmed-down set of features, a medium set of features, and one with a maximum set of features. This will cover the widest range of people who want and use the product.[12]
  • In communication, the Goldilocks principle describes the amount, type, and detail of communication necessary in a system to maximize effectiveness while minimizing redundancy and excessive scope on the "too much" side and avoiding incomplete or inaccurate communication on the "too little" side.[13]
  • In statistics, the "Goldilocks Fit" references a linear regression model that represents the perfect flexibility to reduce the error caused by the bias and variance.
  • In design sprint, the "Goldilocks Quality" means to create a prototype with just enough quality to evoke honest reactions from customers.[14]
  • In machine learning, the Goldilocks learning rate is the learning rate that results in an algorithm taking the fewest steps to achieve minimal loss. Algorithms with a learning rate that is too large often fail to converge at all, while those with too small a learning rate take too long to converge.[15]
