PSYC 1010 Lecture 23 Notes
Introduction
Physicist Niels Bohr
• Give half the members of a group some purported psychological finding, and give the
other half an opposite result.
• Tell the first group, Psyhologists hae foud that separatio eakens romantic
attraction.
• As the sayig goes, Out of sight, out of id.
• Ask them to imagine why this might be true.
• Most people can, and nearly all will then view this true finding as unsurprising.
• Tell the seod group the opposite, Psyhologists have found that separation
strengthens romantic attraction.
• As the sayig goes, Asee akes the heart gro foder.
• People given this untrue result can also easily imagine it, and most will also see it as
unsurprising.
• When opposite findings both seem like common sense, there is a problem.
• Such errors in our recollections and explanations show why we need psychological
research.
• Just asking people how and why they felt or acted as they did can sometimes be
misleading—not because common sense is usually wrong
• Because common sense more easily describes what has happened than what will
happen.
• As physiist Niels Bohr reportedly jested, Preditio is ery diffiult, espeially aout
the future.
• More than 800 scholarly papers have shown hindsight bias in people young and old
from across the world (Roese & Vohs, 2012).
• Neertheless, Grada’s ituitio is ofte right.
