> How hard is it to guess what countCustomers(list) or incrementCustomersScore(list, n) is doing? The correct comparison is: 1. what is the cumulative time wasted when people guess wrong? 2. what is the cumulative time spent writing out a meaningful name? When I'm conservative in my estimate of how good people are at guessing my intuitions, I always find that #1 seems to dwarf #2.
