- Cork Effect: A surfing technique used to gain momentum quickly, created by pulling the board towards you, dipping the back end under the water's surface -- when the board bobs back up, lay flat again and paddle
- Boomerang Effect: A situation where people tend to pick the opposite of what something or someone is saying or doing because of how it is presented to them
- Zeigarnik Effect: Postulates that people remember unfinished or interrupted tasks better than completed tasks. Sportswriter Matt Moore has suggested that the Zeigarnik effect could explain the widespread criticism of the National Basketball Association in allowing free throws for a player "chucking it up whenever a guy comes near them". There is a stoppage of play with each foul. When repeatedly done, it is felt to build up a cognitive bias against this move. The criticism necessitated a rule change penalizing this activity, known as the Harden Rule, named after its most prominent user, James Harden.
- Ikea Effect: A cognitive bias in which consumers place a disproportionately high value on products they partially created. A 2011 study found that subjects were willing to pay 63% more for furniture they had assembled themselves than for equivalent pre-assembled items.
- Barnum Effect (or Forer Effect): A common psychological phenomenon whereby individuals give high accuracy ratings to descriptions of their personality that supposedly are tailored specifically to them, yet which are in fact vague and general enough to apply to a wide range of people. This effect can provide a partial explanation for the widespread acceptance of some paranormal beliefs and practices, such as astrology, fortune telling, aura reading, and some types of personality tests.
- Diderot Effect: A phenomenon that occurs when acquiring a new possession leads to a spiral of consumption that results in the acquisition of even more possessions. In other words, it means that buying something new can cause a chain reaction of buying more and more things because the new item makes one feel like one needs other things to go with it or to keep up with it. This can lead to overspending and accumulating more possessions than one actually needs or uses.
