3. Now consider the last time you chose a place to live. You probably did some
independent research among experts who know something about the subject,
gathered information about prices from a variety of sources, and considered
the costs and benefits of renting versus buying.
4. This is called controlled processing, a detailed consideration of evidence and
information relying on facts, figures, and logic.
a. Controlled processing requires effort and energy, but it’s harder to fool
someone who has taken the time and effort to engage in it.
5. There are a few rules of thumb for determining what types of processing an
audience will use.
B. Interest Level
1. One of the best predictors of whether people will use an automatic or
controlled process for reacting to a persuasive message is their level of interest
in it.
2. Interest levels reflect the impact a decision is going to have on your life.
a. When people are very interested in the outcome of a decision, they’re
more likely to process information carefully.
b. That’s probably why people look for so much more information when
deciding about something important (like where to live) than something
relatively unimportant (like which soda to drink).
C. Prior Knowledge
1. People who are very well informed about a subject area are also more likely to
use controlled processing strategies.
a. They have already thought through various arguments for or against a
specific course of action, and therefore they won’t readily change their
position unless very good, thoughtful reasons are provided.
2. On the other hand, people who are poorly informed about a topic can change
their minds more readily, even in the face of fairly superficial arguments
presented without a great deal of evidence.
a. In other words, a better informed audience is likely to be much harder to
persuade.
D. Personality
1. Are you the type of person who always likes to read at least five reviews of a
movie before deciding whether to see it?
a. If so, you are probably high in need for cognition, a personality trait of
individuals who are most likely to be persuaded by evidence and facts.
their evaluation of persuasive messages.
E. Message Characteristics
1. Another factor that influences whether people use an automatic or controlled
processing strategy is the characteristics of the message itself.
a. Messages provided through relatively lean communication channels, with
to encourage automatic processing.
