The very last happiness piece in the Monsters of Mind collection. The idea of bio-happiness is controversial. But science is making it more and more of a reality, and we must consider how we want to respond to it. Drugs such as SSRIs and MDMA are already well-known to increase happiness (albeit with unintended side-effects), and developments in science and technology will allow us to improve on these agents. Genetic screening already exists, and there isn’t much stopping us from screening for genes that would predict higher baselines of happiness.
