As cognitive neuroscience has advanced, the list of prospective internal, biological enhancements has steadily expanded. Education and training, as well as the use of external information‐processing devices, may be labeled as “conventional” means of cognition enhancement (CE). They are often well established and culturally accepted. By contrast, methods of enhancing cognition through “unconventional” means, such as ones involving deliberately created nootropic drugs, gene therapy, or neural implants, are nearly all to be regarded as experimental at the present time. Transcranial magnetic (...) stimulation (TMS), genetic interventions, brain‐computer interfaces and new senses are highly experimental and unlikely to be important over the next 15 years. Many of the concerns about enhancement are nonspecific to the tools used to achieve it, which means that enhancement–ethic scrutiny should also apply to nonbiological external enhancements. (shrink)
