There are two types of information: permanent and expiring. Permanent information is: “How do people behave when they encounter a risk they hadn’t fathomed?” Expiring information is: “How much profit did Microsoft earn in the second quarter of 2005?” Expiring knowledge catches more attention than it should, for two reasons. One, there’s a lot of it, eager to keep our short attention spans occupied. Two, we chase it down, anxious to squeeze insight out of it before it loses relevance.
