Which of the following is a valid conclusion from the studies discussed in your textbook which used the thin-slice technique to investigate quick judgments about the personal qualities of others?

A) Quick judgments are generally more accurate than judgments based on more information.
B) Judgments based on a lot of information are generally more accurate than judgments based on "thin slices."
C) Quick judgments and those made with more information are remarkably similar.
D) Quick judgments tend to be more negative than judgments based on more information.

Answer: C
Rationale: Using the thin-slices method, researchers found that participants who watched 30 seconds of a college lecture (without sound) gave instructor ratings that were remarkably similar to the end-of-semester ratings of that same class. Additional research has shown even higher levels of agreement when rating high school teachers and using even thinner slices—even as short as 6 seconds!
