Wireheading vs the Hedonistic Imperative
David Pearce   Jun 11, 2014   Adam Ford  

IEET contributor Adam Ford talks with IEET fellow David Pearce about wireheading and reward circuitry.

- A brain–computer interface (BCI), sometimes called a mind-machine interface (MMI), or sometimes called a direct neural interface (DNI), synthetic telepathy interface (STI) or a brain–machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions.

- Evolutionary pressure (selection pressure): Any cause that reduces reproductive success in a proportion of a population potentially exerts evolutionary pressure or selection pressure. With sufficient pressure, inherited traits that mitigate its effects - even if they would be deleterious in other circumstances - can become widely spread through a population. It is a quantitative description of the amount of change occurring in processes investigated by evolutionary biology, but the formal concept is often extended to other areas of research. In population genetics, selection pressure is usually expressed as a selection coefficient
