Supernormal Stimuli reptile brain - Stuart McMillen

This comic applies the concept of 'supernormal stimuli', borrowed from studies of animal behavior, to modern humans. We are contending with exaggerated stimuli — fast food, video games, pornography — that are far more intense and stimulating than anything that was available in the environments that our ancestors evolved to survive in. As a result, modern humans are especially susceptible to become hooked by certain features of modern life.
