In a study on the anchoring heuristic that is described in the textbook,students were given a relatively high,arbitrary identification number to copy into their questionnaires,and then were asked to estimate the number of physicians listed in a telephone book.Some students were warned that the ID number might affect their judgments.What did the researchers discover?
A)students who were warned performed more accurately than control group students.
B)the use of the anchoring heuristic led to more accurate responses in all students.
C)the estimates were affected by the arbitrary identification number,even when students were warned.
D)the estimates were rarely affected by the arbitrary number,regardless of whether students were warned.

Question

Quizplus · Accepted Answer

The researchers discovered that the estimates were affected by the arbitrary identification number, even when students were warned. This suggests that the anchoring heuristic can still influence judgments even when people are aware of its potential biases. Option A is incorrect as it suggests that the warning had a positive impact on accuracy, which is not supported by the study. Option B is incorrect as the use of the anchoring heuristic was not found to lead to more accurate responses. Option D is incorrect as it suggests that the arbitrary number had little to no effect on estimates, which is contradicted by the findings of the study.
