Why Bioenhancement of Mathematical Ability Is Ethically Important

by Julian Savulescu

In a paper just released today, Cohen Kadosh and colleagues (Cohen Kadosh et al., Modulating Neuronal Activity Produces Specific and Long-Lasting Changes in Numerical Competence, Current Biology (2010), doi:10.1016/j.cub.2010.10.007) described how they increased the numerical ability of normal people by applying an electrical current to a part of the skull. So what? Most of us don’t do that much maths after leaving school and manage just fine.
