When imagining the possible influences of efficient cognitive enhancers on society as a whole, there can be many positive effects. Such drugs may enable individuals to perform better and enjoy more achievements and success. However, cognitive enhancers may have a darker side. Fears have been raised of an overworked 24/7 society pushed to the limits of human endurance, or of direct and indirect coercion into taking such drugs. If other children at school or colleagues at work are taking cognitive-enhancing drugs, will you feel pressure to give them to your children or take them yourself? What if a perfectly safe and reliable cognitive enhancer existed, could society deny it to healthy individuals who may benefit from it?
