What they argue

Dan Ariely is a researcher who explores the psychological patterns underlying human behavior, specifically focusing on why people act in ways that defy classical economic logic. He investigates how consistent, predictable biases and internal narratives shape our decisions, perceptions of value, and moral choices.

  1. Predictable Irrationality

    Human behavior is not random but is governed by consistent, underlying psychological patterns. While our decisions may defy logic, they can be mapped, predicted, and managed.

    • Says much the same Richard H. Thaler — Predictable IrrationalityHuman behavior is not random but follows consistent patterns of bias rooted in our evolutionary history and cognitive limitations. We are systematically biased rather…Misbehaving

  2. The Endowment Effect

    People value things more highly simply because they own them. The psychological pain of losing an object is significantly greater than the joy of gaining that same object.

    • Says much the same Richard H. Thaler — Loss AversionThe psychological pain of losing is roughly twice as powerful as the joy of gaining the same amount. This explains why investors often hold onto 'loser' stocks for too…Advances in behavioral finance

  3. Relativity

    We do not judge things in a vacuum; instead, we judge them by comparing them to other things. Our perception of value is entirely dependent on the context provided by the alternatives available to us.

    • A related idea Oliver Sacks — Perception vs. RecognitionSacks distinguishes between the ability to see, which is raw sensory input, and the ability to recognize, which is the cognitive labeling of that input. He argues that…The Man Who Mistook His Wife for a Hat

  4. The Decoy Strategy

    This is a method of framing choices to influence someone's selection between two options. It involves identifying a target option and using a decoy to make that choice more appealing.

    From Predictably Irrational (book)

  5. The Self-Concept as a Moral Compass

    Our behavior is guided by the internal story we tell ourselves about who we are. We act in ways that remain consistent with our internal identity.

    From The honest truth about dishonesty (book)

    • Says much the same George A. Akerlof — Identity ConstraintIndividuals have a self-concept that acts as a boundary for acceptable behavior, making choices based on whether they fit their internal narrative. We view ourselves as…Identity economics

  6. The Social Construction of Dishonesty

    Dishonesty is a social and psychological construct rather than a purely biological one. We cheat not because we are 'bad' people, but because we want to believe we are still 'good' people while doing something wrong.

    From The honest truth about dishonesty (book)

Every idea names the summary it came from. Written by a local model from this mind’s own work, never from memory.
