Identifying Critical Thinking
Hindrances
This tutorial will give you practice in recognizing four
common critical thinking hindrances: egocentrism,
sociocentrism, unwarranted assumptions and
stereotypes, and wishful thinking.

In a 1989 international study of 13-year-olds, Koreans
finished first in mathematics and Americans finished last.
Yet when asked whether they thought they were "good at
mathematics," only 23 percent of Koreans said "yes,"
compared to 68 percent of Americans.
Based on what you have learned in this chapter,
which critical thinking hindrance do the American
youngsters in this study demonstrate?

Egocentrism.
Egocentrism is self-centered thinking. Chapter 1
discusses two major forms of egocentrism: selfinterested thinking and self-serving bias.
Which form of egocentrism do the American students
exhibit: self-interested thinking or self-serving bias?

Self-serving bias.
Self-serving bias is the tendency to overrate oneself--to be
overly confident of one's knowledge, abilities, or good
fortune.
The American students in this study certainly don't lack
"self-esteem." What they do lack is a proper sense of how
little they know about mathematics.

Muhammad Ali [speaking in Zaire, Africa]: "There's no
country as great as the smallest city in America. I mean
[here in Zaire] you can't watch television. The water won't
even run right. The toilets won't flush. The roads, the cars—
there's nothing as great as America."
Based on your reading of this chapter, what type of
critical thinking hindrance does Muhammad Ali display
in this passage? .

Sociocentrism.
Sociocentrism is group-centered thinking, i.e., thinking that is
excessively influenced by group standards of conduct or belief.
Chapter 1 discusses two major forms of
sociocentrism: group bias and the herd instinct.
What form of sociocentrism does Ali display in
this passage: group bias or the herd instinct?

Group bias.
Group bias is the tendency to think more highly of one's nation, race,
school, family, or other social group than is warranted by the
evidence.
In saying, for example, that "there's no country as great as the
smallest city in America," Ali is clearly overstating the
comparative virtues of his own country, and thus is guilty of
group bias.

Sexually active bisexual: “I’ll never get AIDS. I’m a very
intuitive person. I would sense it if someone had something as
degenerative as the AIDS virus.”
Based on your reading of this chapter,

this person exhibit?

Sexually active bisexual: “I’ll never get AIDS. I’m a very
intuitive person. I would sense if someone had something as
degenerative as the AIDS virus.”
Wishful thinking.
Wishful thinking occurs when a person believes that something is
true, not because they have good reasons for the belief, but because
they wish it were true.
Persons who engage in risky sexual activity often kid
themselves in thinking, “It won’t happen to me.”
Notice that this is also a case of self-serving bias. This person
is overly confident of his or her ability to know “intuitively”
when a potential sexual partner has the AIDS virus.

Ed: My friend Dirk is a college sophomore at a state university
in upstate New York. He is blonde, loves surfing, and has a very
laid-back personality.
Mary: I bet he’s from California.
Based on your reading of this chapter, which critical
thinking hindrance does Mary exhibit?
Ed: My friend Dirk is a college sophomore at a state university
in upstate New York. He is blonde, loves surfing, and has a very
laid-back personality.
Mary: I bet he’s from California.
Stereotyping.
Having blonde hair, enjoying surfing, and having a laid-back
personality are qualities people stereotypically associate with
Californians--and this despite the fact that a majority of Californians
are not Caucasians. But of course many people who are not from
California also have these three qualities. And given that Dirk
attends a state university in upstate New York, it is unlikely, in fact,
that he comes from California.
