We don’t yet have a commercially available “thinking cap” but we will soon. So the research community has begun to ask: What are the ethics of battery-operated cognitive enhancement? Last week a group of Oxford University neuroscientists released a cautionary statement about the ethics of brain boosting, followed quickly by a report from the UK’s Royal Society that questioned the use of tDCS for military applications. Is brain boosting a fair addition to the cognitive enhancement arms race? Will it create a Morlock/Eloi-like social divide where the rich can afford to be smarter and leave everyone else behind? Will Tiger Moms force their lazy kids to strap on a zappity helmet during piano practice?
After trying it myself, I have different questions. To make you understand, I am going to tell you how it felt. The experience wasn’t simply about the easy pleasure of undeserved expertise. When the nice neuroscientists put the electrodes on me, the thing that made the earth drop out from under my feet was that for the first time in my life, everything in my head finally shut the fuck up.
The experiment I underwent was accelerated marksmanship training on a simulation the military uses. I spent a few hours learning how to shoot a modified M4 close-range assault rifle, first without tDCS and then with. Without it I was terrible, and when you’re terrible at something, all you can do is obsess about how terrible you are. And how much you want to stop doing the thing you are terrible at.
Then this happened:
The 20 minutes I spent hitting targets while electricity coursed through my brain were far from transcendent. I only remember feeling like I had just had an excellent cup of coffee, but without the caffeine jitters. I felt clear-headed and like myself, just sharper. Calmer. Without fear and without doubt. From there on, I just spent the time waiting for a problem to appear so that I could solve it.
