Provided it’s done in a safe and healthy way, I’m in favor of all sorts of performance enhancement. The idea of human “purity” is a lie that we tell ourselves while behaving counter to it. In his post, “The Ethics of Brain Boosting,” Jonathan Wood examines the ramifications of transcranial direct current stimulation or TDCS, which seems to enhance brain function. An excerpt:

“Dr Roi Cohen Kadosh, who has carried out brain stimulation studies at the Department of Experimental Psychology, very definitely has a vision for how TDCS could be used in the future: ‘I can see a time when people plug a simple device into an iPad so that their brain is stimulated when they are doing their homework, learning French or taking up the piano,’ he says.

The growing number of positive results in early-stage studies, led the neuroscientists Dr Cohen Kadosh and Dr Jacinta O’Shea to talk to Professor Neil Levy, Dr Nick Shea and Professor Julian Savulescu in the Oxford Centre for Neuroethics about what ethical issues there may be in future widespread use of TDCS to boost abilities in healthy people.

The researchers outline the issues in a short paper in the journal Current Biology, and indicate the research that is now necessary to address some of the potential concerns.

‘We ask: should we use brain stimulation to enhance cognition, and what are the risks?’ explains Roi. ‘Our aim was to look at whether it gives rise to new ethical issues, issues that will increasingly need to be thought about in our field but also by policymakers and the public.’” (Thanks Browser.)
