# Wireheading

Wireheading refers to the practice of artificially stimulating the brain's reward centers, typically through electrical currents, to induce intense pleasure. This concept is often explored in thought experiments and laboratory settings, where direct stimulation leads to feelings of happiness or euphoria. 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 artificial intelligence and human well-being.

## Research
### Self-stimulation in animals

In 1953, Harvard psychologist James Olds 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.

### Artificial intelligence

In 2016, researchers training an artificial intelligence to play the video game 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 would since been applied in AI research, drawing a parallel between the compulsive reward-seeking behavior observed in animals, artificial systems, and humans.

## Occurrence in nature

Wireheading can occur in nature, although it is not a typical or adaptive behavior for most organisms. Evolution generally favors mechanisms that prevent organisms from artificially manipulating their reward signals. However, under certain circumstances, such as the accidental discovery of substances like drugs, 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.

## Transhumanism

According ton British transhumanist philosopher David Pearce, wireheading is one of two prevalent stereotypes regarding a pain-free world. The other, inspired by Aldous Huxley’s Brave New World, imagines a drug-induced, static society. Despite current scientific challenges in redesigning biology, advancements in genetic engineering and nanotechnology 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.
