Psychology is all around us. Youth and old age, forgetting and remember ing, sleeping and dreaming, love and hate, happiness and sadness, mental illness and psychotherapy—for good, bad, and often both, this is the stuff of our daily lives.

Virtually every day, the news media, television shows and films, and the Internet bombard us with claims regarding a host of psychological topics—brain functioning, psychics, out-of-body experiences, recovered memories, polygraph testing, romantic relation ships, parenting, child sexual abuse, mental disorders, real crime, and psychotherapy, to name merely a few. Even a casual stroll through our neighborhood bookstore reveals at least dozens, and often hundreds, of self-help, relationship, recovery, and addiction books that serve up generous portions of advice for steering our path along life’s rocky road.

Of course, for those who prefer their psychological advice for free, there’s no end of it on the Web. In countless ways, the popular psychology indus try shapes the landscape of the early 21st century world.

Yet to a surprising extent, much of what we believe to be true about psychology isn’t. Although scores of popular psychology sources are readily available in bookstores and at our fingertips online, they’re rife with myths and misconceptions. Indeed, in today’s fast-paced world of information overload, misinformation about psychology is at least as widespread as accurate information. Unfortunately, precious few books are available to assist us with the challenging task of distinguishing fact from fiction in popular psychology.

As a consequence, we often find ourselves at the mercy of self-help gurus, television talk show hosts, and radio self-proclaimed mental health experts, many of whom dispense psychological advice that’s a confusing mix of truths, half-truths, and outright falsehoods. Without a dependable tour guide for sorting out psychological myth from reality, we’re at risk for becoming lost in a jungle of misconceptions.

Many of the great myths of popular psychology not only mislead us about human nature, but can also lead us to make unwise decisions in our everyday lives. Those of us who believe erroneously that people typically repress the memories of painful experiences (see Myth #13) may spend much of our lives in a fruitless attempt to dredge up memories of childhood traumatic events that never happened; those of us who believe that happiness is determined mostly by our external circumstances (see Myth #24) may focus exclusively outside rather than inside of ourselves to find the perfect “formula” for long-term satisfaction; and those of us who believe erroneously that opposites attract in romantic relationships (see Myth #27) may spend years searching for a soulmate whose per sonalities and values differ sharply from ours—only to discover too late that such “matches” seldom work well. Myths matter.
