This information was always apparent. It existed in plain sight. But random sampling of the bouts might have failed to reveal it. Even though it relied on basic statistics, without knowing what to look for, one would have no idea what sample to use.

We don’t give up on exactitude entirely; we only give up our devotion to it. What we lose in accuracy at the micro level we gain in insight at the macro level. These two shifts lead to a third change, which we explain in Chapter Four: a move away from the age-old search for causality. As humans we have been conditioned to look for causes, even though searching for causality is often difficult and may lead us down the wrong paths. In a big-data world, by contrast, we won’t have to be fixated on causality; instead we can discover patterns and correlations in the data that offer us novel and invaluable insights.

This delay completely blinded public health agencies at the most crucial moments.
