Persistence and communication skill drive hits
That is to say: keeping productivity equal, the scientists were as likely to score a hit at age 50 as at age 25. The distribution was random; choosing the right project to pursue at the right time was a matter of luck.
Yet turning that fortuitous choice into an influential, widely recognized contribution depended on another element, one the researchers called Q.
Q could be translated loosely as “skill,” and most likely includes a broad variety of factors, such as I.Q., drive, motivation, openness to new ideas and an ability to work well with others. Or, simply, an ability to make the most of the work at hand: to find some relevance in a humdrum experiment, and to make an elegant idea glow.
