Exceptions Become the Rule
NEW YORK – Long ago, I worked as an analyst on Wall Street. The first company that I analyzed was Federal Express, which at the time had not yet shipped its first package.
The idea behind FedEx was simple and compelling: The cost of complexity was higher than the cost of air transport, so the company would ship all its packages overnight to Memphis, Tennessee. By radically simplifying the myriad combinations of start and end points – the only routes were to and from Memphis – all of the packages could be delivered the next day reliably.
All of that has changed, thanks to developments in information technology. With today’s powerful computers, we can look at massive amounts of information and simulate complex situations, making pretty good predictions about many things: What will traffic flows look like on Tuesday at 5:00 in the afternoon if we put a detour at this highway intersection? What percentage of people on this drug will get better – and, more interestingly, which particular individuals will respond positively, and which ones are likely to be harmed?
