Looking at the career histories of thousands of scientists, artists, and film directors, the team found evidence that hot streaks are both real and ubiquitous, with virtually everyone experiencing one at some point in their career. While the timing of an individual’s greatest successes is indeed random, their top hits are highly likely to appear in close proximity. About 90 percent of individuals had at least one hot streak and an individual’s top-two works were roughly 50 percent more likely to occur back-to-back.
