57 PEOPLE ARE INHERENTLY LAZY
It might be exaggerating a bit to say that people are inherently lazy. But research does
show us that people will do the least amount of work possible to get a task done.
IS LAZY ANOTHER WORD FOR EFFICIENT?
Over eons of evolution, humans have learned that they will survive longer and bet-
ter if they conserve their energy. You want to spend enough energy to have enough
resources (food, water, sex, shelter), but beyond that you are wasting your energy if
you spend too much time running around getting or doing more stu. Of course, ques-
tions about how much is enough, and whether we have enough stu yet, and how long
should the stu last (and on and on), still vex us, but putting the philosophical questions
aside, for most activities, most of the time, humans work on a principle called satisficing.
SATISFY PLUS SUFFICE EQUALS SATISFICE
Herbert Simon is credited with coining the term satisfice. He used it to describe a deci-
sion-making strategy in which the person decides to pick the option that is adequate,
rather than optimal. The idea of satisficing is that the cost of making a complete analysis
of all the options is not only not worth it, but may be impossible. According to Simon we
often don’t have the cognitive faculties to weigh all the options. So it makes more sense
to make a decision based on “what will do” or what is “good enough” rather than trying
to find the optimal or perfect solution. If people satisfice rather than optimize, there are
implications for the design of Web sites, software, and other products.
DESIGN WEB SITES FOR SCANNING, NOT READING
In his book Don’t Make Me Think (2005), Steve Krug applies the idea of satisficing to the
behavior you can observe when someone comes to your Web site. You’re hoping the visi-
tor will read the whole page, but, as Krug says, “What they actually do most of the time (if
we’re lucky) is glance at each new page, scan some of the text, and click on the first link
that catches their interest or vaguely resembles the thing they’re looking for. There are
usually large parts of the page that they don’t even look at.” Krug talks about Web pages
being like billboards. You have to assume that people are taking a quick glance.
Keeping this idea in mind, look quickly at the following four screenshots of the home
pages of several state government Web sites in the U.S. Imagine that you’re making a trip
to the state, and you’re looking for tourism information. Don’t study any of the pages, just
glance briefly at Figure57.1, Figure57.2, Figure57.3, and Figure57.4.
