Seven days every day
Imagine someone of the type we call neurotic in common parlance. He is wiry, looks contorted, and speaks with an uneven voice. His neck moves around when he tries to express himself. When he has a small pimple his first reaction is to assume that it is cancerous, that the cancer is of the lethal type, and that it has already spread. […] In the office, he is tuned to every single possible detail, systematically transforming every molehill into a mountain. The last thing you want in life is to be in the same car with him when stuck in traffic on your way to an important appointment. The expression overreact was designed with him in mind: he does not have reactions, just overreactions.
Compare him to someone with the opposite temperament, imperturbable, with the calm under fire that is considered necessary to become a leader, military commander or a mafia godfather. Usually unruffled and immune to small information —they can impress you with their self-control in difficult circumstances. For a sample of a composed, calm and pondered voice, listen to interviews of “Sammy the Bull” Salvatore Gravano who was involved in the murder of nineteen people (all competing mobsters). He speaks with minimal effort. In the rare situations when he is angry, unlike with the neurotic fellow, everyone knows it and takes it seriously.
The supply of information to which we are exposed under modernity is transforming humans from the equable second fellow to the neurotic first. For the purpose of our discussion, the second fellow only reacts to real information, the first largely to noise. The difference between the two fellows will show us the difference between noise and signal. Noise is what you are supposed to ignore; signal what you need to heed. […]
A not well discussed property of data: it is toxic in large quantities —even in moderate quantities.
