Practical Ethics

If ‘neurotechnology’ isn’t a glamour area for researchers yet, it’s not far off. Technologies centred upon reading the brain are rapidly being developed. Among the claims made of such neurotechnologies are that some can provide special access to normally hidden representations of consciousness. Through recording, processing, and making operational brain signals we are promised greater understanding of our own brain processes. Since every conscious process is thought to be enacted, or subserved, or realised by a neural process, we get greater understanding of our consciousness.

Besides understanding, these technologies provide opportunities for cognitive optimisation and enhancement too. By getting a handle on our obscure cognitive processes, we can get the chance to manipulate them. By representing our own consciousness to ourselves, through a neurofeedback device for instance, we can try to monitor and alter the processes we witness, changing our minds in a very literal sense.

This looks like some kind of technological mind-reading, and perhaps too good to be true. Is neurotechnology overclaiming its prospects? Maybe more pressingly, is it understating its difficulties? Continue reading →
