7. Consider this statement: "At times you are extroverted, affable, and sociable, while at other times you are introverted, wary, and reserved." What is it that probably makes such declarations so believable to so many people, given what you now know about the Barnum effect?

the answer to the question is punishment. or more specifically, positive punishment.

positive punishment occurs when a behavior is given a negative consequence for the individual doing the behavior.

sara no longer wants to ask questions (the behavior) because she is ridiculed by mr. smith (the punishment).

reinforcement is inaccurate because reinforcement always gives positive consequences for the individual doing the behavior, be it by introducing a pleasant consequence or removing an unpleasant one.
