Of course, if we were able to watch a great athlete training, or a great writer writing, or a great coder coding, we would see that honing a strength is hard work—it is by no means easy to find that incremental margin of performance when you are already operating at a high level—and that a strength is not where we are most “finished” but in fact where we are most productively challenged. Yet we are told to resist the temptation to “just” play to our strengths, and instead to work constantly on our weaknesses. In common parlance, we are told to avoid “running around our backhand.” This betrays, perhaps, a misunderstanding of what a strength actually is. It is not, for each of us, where performance is easiest—it is where performance is most impactful and increasing.

It’s also important to realize that even if people have a fixed mindset, they’re not always in that mindset. In fact, in many of our studies, we put people into a growth mindset. We tell them that an ability can be learned and that the task will give them a chance to do that. Or we have them read a scientific article that teaches them the growth mindset. The article describes people who did not have natural ability, but who developed exceptional skills. These experiences make our research participants into growth-minded thinkers, at least for the moment - and they act like growth-minded thinkers, too.

The benefit of this transparency was not immediately felt (and, notably, when we decided upon it, we weren’t even counting on a payoff; it just seemed like the right thing to do). But the relationships and connections we formed, over time, proved far more valuable than we could have imagined, fueling our technical innovation and our understanding of creativity in general.

This finding suggests that it may be the tangibility, rather than the magnitude, of the benefits that makes people care. You don’t have to promise riches and sex appeal and magnetic personalities. It may be enough to promise reasonable benefits that people can easily imagine themselves enjoying.

One of the advantages of having pairs to study is that we can see how two people engaged in similar activities can differ radically in how they operate. This shows that their successful practices are only partly a function of the type of work they do, and largely a reflection of how the individual is encoded. To illustrate, let's look at the other writer in our study, Barbara Tuchman.
