Get the Picture

You and I haven’t met, but I feel as if I already know you. You’re pretty smart. Above average, in fact. And when you have a goal in front of you—whether it’s completing a work project by the deadline, writing that term paper or getting all the dinner-party details just right—you’re sure you’ll rise to the occasion.

Me, too. Trouble is, we’re often so very wrong about our overconfident self-assessments—and we are blind to that ignorance because we can’t get a complete view of ourselves, as psychologists David Dunning, Chip Heath and Jerry M. Suls explain in their article “Picture Imperfect.” Our muddled thinking impairs thousands of our everyday decisions, affecting our health, education and interactions in the workplace. Hilariously (at least in hindsight), I became the embodiment of that principle when I promised to shape the authors’ original 35,000-word paper into a 3,500-word story for this issue in “just a few days.” A few weeks later an unsurprised but nonetheless amiable Dunning and company finally saw that edit. Turn to page 20 for the results.

Memories of such embarrassing failures are easy to laugh off. But what about harrowing, even traumatic, events that have been seared into our brains? They can haunt our waking hours and nightmares for years, if we ever make peace with them at all. What if we could simply delete these mental blemishes? In our cover story on “Erasing Memories,” beginning on page 28, neuroscientist R. Douglas Fields reports how research could create the “spotless mind.” Could the work be a balm for an anxiety-ridden culture—or put us on the numbing path of reflexively pill-popping our problems away, Brave New World-style?


On supporting science journalism

If you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.


By the way, I wasn’t completely teasing about getting to know you. In the past, we have invited readers to sign up as advisers (www.sciam.com/feedback/). Now, in response to feedback, we have added two new features: a Calendar of worthwhile events, on page 19, and Ask the Brains, in which experts answer your questions about psychology and neuroscience, on page 94. We have also expanded the popular Illusions column, by neuroscientists Vilayanur S. Ramachandran and Diane Rogers-Ramachandran, starting on page 16. Of course, we think you’ll like them—but we will try to understand it if you tell us we are being overconfident in that self-assessment.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
