"We eat in restaurants, buy branded toiletries, build 
  skyscrapers, create legislative institutions, travel in 
  flying machines, write poetry, and search for meaning in 
  relationships, temples, and scientific books. Humans have 
  discovered antibiotics, sent probes into space, decimated 
  rainforests, shared a billion views of clips of kitten 
  behaviour, and decoded their own genomes.


  But there is one thing that humans have singularly failed 
  to do, and that is to properly understand their own behaviour. "
