PSYC 1010 Lecture 24 Notes
Introduction
Overconfidence
• Many people believe that love breeds happiness, and they are right (we have what
researhers idetify as a deep eed to elog).
• Indeed, noted Daniel Gilbert, Brett Pelham, and Douglas Krull (2003), good ideas in
psychology usually have an oddly familiar quality
• The moment we encounter them we feel certain that we once came close to thinking
the same thing ourselves and simply failed to write it down.
• Good ideas are like good inventions: Once created, they seem obvious.
• Why did it take so long for someone to invent suitcases on wheels and Post-it Notes?
• But soeties Grada’s ituitio, ifored y outless asual oseratios, is
wrong.
• In other modules, we will see how research has overturned popular ideas
• Familiarity breeds contempt, that dreams predict the future, and that most of us use
only 10 percent of our brain.
• We ill also see ho it has surprised us ith disoeries aout ho the rai’s heial
messengers control our moods and eories, aout other aials’ ailities
• About the effects of stress on our capacity to fight disease
• We humans tend to think we know more than we do.
• Asked how sure we are of our answers to factual questions (Is Boston north or south of
Paris?), we tend to be more confident than correct.
• Or consider these three anagrams, which Richard Goranson (1978) asked people to
unscramble
• WREAT → WATER ETRYN → ENTRY GRABE → BARGE
• About how many seconds do you think it would have taken you to unscramble each of
these?
