For a class project, Brenda read about the results of several studies investigating the causes of schizophrenia. Some of the studies seemed to indicate that schizophrenia is genetic,

while others indicated that schizophrenia could be triggered by environmental factors. Eventually, Brenda had to accept that schizophrenia is a complicated disease, and that there probably is not a clear-cut reason why some people develop it. This illustrates what critical thinking habit?
A) examine assumptions and biases
B) examine the nature and source of the evidence
C) tolerate ambiguity
D) consider alternatives

Answer: C
Rationale: Tolerating ambiguity refers to the ability to accept situations where there is not a clearly defined answer. People who tolerate ambiguity recognize that most complex issues do not have clear-cut answers.
