Wireheading refers to the practice of artificially stimulating the brain's reward centers, typically through electrical currents, to induce intense

pleasure Pleasure is experience that feels good, that involves the enjoyment of something. It contrasts with pain or suffering, which are forms of feeling bad. It is closely related to value, desire and action: humans and other conscious animals find ...

. However, wireheading can also refer more broadly to methods that produce counterfeit utility by maximizing pleasurable experiences without contributing to long-term value or fulfillment. While it may offer immediate gratification, wireheading is criticized for potentially undermining meaningful experiences such as love, creativity, and personal growth. The concept raises ethical concerns, especially in relation to

Self-stimulation in animals

James Olds James Olds (May 30, 1922 – August 21, 1976) was an American psychologist who co-discovered the pleasure center of the brain with Peter Milner while he was a postdoctoral fellow at McGill University in 1954. He is considered to be one of the fo ...

discovered the brain's "pleasure centers" through an experiment where rats compulsively stimulated their brains by pulling a lever, achieving over 1,900 responses an hour. Olds and Peter Milner’s findings suggested the rats experienced intense pleasure, but later research indicated that the rats might have been driven by pure craving, rather than pleasure. This phenomenon, now called wireheading, showed how the pursuit of reward could override survival needs, potentially leading to self-starvation. Similar experiments with other animals, including monkeys and dolphins, demonstrated that excessive self-stimulation could lead to harmful, maladaptive behavior, raising concerns about the potential dangers of such compulsive behavior.

Coastrunner observed a peculiar behavior in the AI. Instead of completing the racetrack, the AI repeatedly engaged in an endless loop of collecting items, disregarding the primary objective of finishing the race. This behavior is analogous to the phenomenon first identified in animal studies. Both the AI's actions and the rats' behavior reflect an addiction-like tendency to prioritize rewards over other goals. This concept has since been applied in AI research, drawing a parallel between the compulsive reward-seeking behavior observed in animals, artificial systems, and humans.

s, organisms may inadvertently engage in behavior that mimics wireheading. Evolutionary processes tend to eliminate behaviors that do not contribute to survival or fitness. Furthermore, the ability of organisms to intentionally manipulate their reward signals is limited by cognitive constraints, which generally prevent conscious wireheading. In some cases, organisms may engage in belief manipulation, such as through rituals or ideologies, to experience artificial rewards, but this is distinct from direct neural stimulation.

may eventually eliminate suffering and replace it with continuous well-being. However, ideological resistance persists, as society often justifies the necessity of mental pain. Pearce suggests that a more optimistic future could involve a diverse, empathic form of well-being, where controlled euphoria enhances exploration, empathy, and intelligence, fostering sustained bliss without the negative aspects of present-day pleasure-seeking behaviors.
