1.
Compare and contrast the availability heuristic and the representativeness heuristic.
2.
List and describe three characteristics of a good scientist.
3.
Tavris and Aronson (2007) believe that “science is a form of arrogance control.” Use
what you learned in this chapter to provide support for their claim.

4.
In talking with her friends, Fabiana realizes that many college-aged students still believe
in the existence of Santa Claus. Although few think he is a rosy-cheeked, bearded
character who goes down chimneys, many do believe that he exists in spirit, instilling a
sense of “Christmas cheer” and goodwill during the holiday season. Use you
understanding of belief perseverance to explain why adults may still believe in Santa
Claus.

5.
Mark wonders whether he should pursue a degree in psychology. Help him see the
merit in this major by describing three career skills that he will acquire by studying
research methods and the discipline of psychology.

Answer Key

1.
Both the availability and representativeness heuristics represent biases in human
thinking. These mental shortcuts are used when processing information and making
decisions. By employing heuristics, people save time and energy and they free up
cognitive resources for other tasks. However, both the availability and
representativeness heuristics lead to processing errors. The availability heuristic is the
tendency to assume that events that are easiest to recall occur most frequently. For
instance, those things that make the biggest impact on one's memory are likely to be
given disproportional weight. People may assume that plane crashes are more frequent
than car crashes, because examples of plane crashes are salient in their memory.
However, this bias obscures the fact that many more people die from car crashes each
year. The representativeness heuristic is the tendency to judge an outcome by how
similar it is to the “typical” example of that event. An individual who “looks like a
criminal” may be more likely to receive a conviction from a jury, because he/she is
representative of that mental category. An individual who does not look like a
“typical” criminal may be judged less harshly, as jurors have trouble associating that
person with the schema they hold for that category.

2.
Scientists, whether in the field of psychology or in other disciplines, share certain core
characteristics. These include (but are not limited to): skepticism the tendency to
ask questions about claims in an effort to seek the truth; open-mindedness a
willingness to pursue a deeper understanding about the nature of the world regardless of
whether a topic or idea is unpopular or controversial; objectivity basing claims on
scientific data rather than on personal beliefs or opinions, even on topics with which one
has extensive familiarity or experience; empiricism the willingness to test ideas using
the scientific method (systematic observation, experience, or measurement) to draw
conclusions and admit when personal beliefs are unsupported; creativity the ability to
“think outside the box” and design novel approaches to answer scientific questions; and
communication the ability to share findings in writing or oral presentations with
other scientists in an effort to extend the collective of knowledge and serve the common
good.

3.
Thinking is fraught with flaws and biases. These include (but are not limited to): the
availability heuristic, representativeness heuristic, better-than-average effect,
overconfidence, hindsight bias, confirmation bias, focusing effect, “what you see is all
there is” phenomenon, and belief perseverance. Science counters these natural fallacies
by requiring empirical evidence collected through systematic observation, experience,
and/or measurement in order to make claims. By using science as a foundation, people
are better able to evaluate claims, avoid biases, and make more objective and
well-informed decisions. In doing this, however, people are made aware of the flaws,
biases, and unscientific nature of their own thinking. It is often uncomfortable for
people to accept that they are incorrect. Accordingly, by using science, our errors are
brought to light and our arrogance (about being correct) is controlled.

4.
Belief perseverance is the tendency to maintain a belief despite encountering
contradictory information. Beliefs remain intact by interpreting information in a way
that does not invalidate the original belief. In the case of Santa Claus, this belief is
often one associated with important, cherished memories of one's childhood and family.
