People are quick to make certain judgements. Our minds have evolved to excel at drawing conclusions from minimal data and thinking quickly using heuristics and mental models.

Deep inside the brain is a bundle of around 165,000 neurons, called the dorsal raphe nucleus. When prompted into action, the nucleus produces the neurotransmitter serotonin, which acts as a messenger to other areas of the brain. Two areas often in communication with the dorsal raphe nucleus sit just behind…


Technology is all around us. It is at once so ubiquitous as to be almost invisible, and in other areas so remarkable as to grab the world’s attention.

From ceramic cups to nuclear weapons; from the springs in your mattress to immersive virtual worlds; from paper and pencils to intelligent…
