It was just Brooke Macnamara’s first day as a faculty member at Case Western Reserve University when she had a study published that upended long-held beliefs about the importance of practice on one’s expertise.
The study, published in 2014 in Psychological Science, garnered attention from such publications as The New York Times, Academic Minute, Business Insider and HuffPost.
Macnamara’s highly publicized research questioned how much deliberate practice accounts for differences among people. Her meta-analysis found that a field’s top individuals are not necessarily the ones who practiced the most, contrary to what Swedish psychologist K. Anders Ericsson asserted in the 1990s and Malcolm Gladwell promoted in Outlier: The Story of Success.
And she didn’t just leave it there—she delved deeper and debunked the popular 10,000-hour rule, which claimed that anybody could be an expert with 10,000 hours of practice.
Not long after making those headlines, Macnamara did it again, with a study published in Perspectives on Psychological Science that found that practice accounts for just 1 percent of the difference in performance among elite athletes. With the 2016 Olympics on the horizon, Macnamara’s work again was met by major media attention, this time from the likes of Scientific American, ESPN and The Cut.
Since then, Macnamara has continued to explore cognitive differences, and she’s also recently begun to research mindset—looking at both “growth” and “fixed” mindsets.
Last year, she found no evidence for the “bright girl effect”—in which girls limit themselves because they believe their intelligence to be fixed—at least among adults.
Now, fewer than four years after earning her PhD, the Association for Psychological Science is recognizing Macnamara as a “rising star.”
The recognition is bestowed upon psychological science scholars from around the world who, though in the early stages of their research careers, have already made an impact on the field and whose trajectory points them toward continued success.
