c. The rational decision-making model assumes that the decision maker has
complete information, is able to identify all the relevant options in an unbiased
manner, and chooses the option with the highest utility.
d. Most decisions in the real world don’t follow the rational model.
i. People are usually content to find an acceptable or reasonable solution to a
problem rather than an optimal one.
ii. Choices tend to be limited to the neighborhood of the problem symptom and
the current alternative.
iii. As one expert in decision making put it, “Most significant decisions are made
by judgment, rather than by a defined prescriptive model.”
iv. People are remarkably unaware of making suboptimal decisions.
B. Bounded Rationality
1. When faced with a complex problem, most people respond by reducing the problem
to a level at which it can be readily understood.
a. This is because the limited information-processing capability of human beings
makes it impossible to assimilate and understand all the information necessary to
optimize.
b. People satisfice—they seek solutions that are satisfactory and sufficient.
2. Individuals operate within the confines of bounded rationality. They construct
simplified models that extract the essential features.
3. How does bounded rationality work?
a. Once a problem is identified, the search for criteria and options begins.
b. The decision maker will identify a limited list made up of the more conspicuous
choices, which are easy to find and tend to be highly visible, and they will
represent familiar criteria and previously tried-and-true solutions.
c. Once this limited set of options is identified, the decision maker will begin
reviewing it.
i. The decision maker will begin with options that differ only in a relatively
small degree from the choice currently in effect.
ii. The first option that meets the “good enough” criterion ends the search.
iii. Satisficing is not always a bad idea— a simple process may frequently be
more sensible than the traditional rational decision-making model.
d. To use the rational model in the real world, you need to gather a great deal of
information about all the options, compute applicable weights, and then calculate
values across a huge number of criteria.
i. All these processes can cost time, energy, and money.
ii. If there are many unknown weights and preferences, the fully rational model
may not be any more accurate than a best guess.
iii. Sometimes a fast-and-frugal process of solving problems might be your best
option.
C. Intuition
1. Perhaps the least rational way of making decisions is intuitive decision making, an
unconscious process created from distilled experience.
2. It occurs outside conscious thought; it relies on holistic associations, or links between
disparate pieces of information; it’s fast; and it’s affectively charged, meaning it
usually engages the emotions.
