Not long ago I was interested to read about Marina Semyonova, a great Russian dancer and teacher, who devised a novel way of selecting her students. It was a clever test for mindset. As a former student tells it, “Her students first have to survive a trial period while she watches to see how you react to praise and to correction. Those more responsive to the correction are deemed worthy.”

In other words, she separates the ones who get their thrill from what’s easy - what they’ve already mastered - from those who get their thrill from what’s hard.

The workshop then takes managers through a series of exercises in which a) they consider why it’s important to understand that people can develop their abilities, b) they think of areas in which they once had low ability but now perform well, c) they write to a struggling protégé about how his or her abilities can be developed, and d) they recall times they have seen people learn to do things they never thought these people could do. In each case, they reflect upon why and how change takes place.

After the workshop, there was a rapid change in how readily the participating managers detected improvement in employee performance, in how willing they were to coach a poor performer, and in the quantity and quality of their coaching suggestions. What’s more, these changes persisted over the six-week period in which they were followed up.

Another example of testable credentials comes from Jim Thompson, the founder of the Positive Coaching Alliance (PCA). The mission of the PCA is to emphasize that youth sports should not be about winning at all costs; it should be about learning life lessons.

The lesson for the rest of us is that if we want to make people care, we’ve got to tap into the things they care about. When everybody taps into the same thing, an arms race emerges. To avoid it, we’ve either got to shift onto new turf, as Thompson did, or find associations that are distinctive for our ideas.

My attempts to mold him failed, and I felt increasingly frustrated. He thought I’d fire him. Fortunately, for him and me, I began to grasp that he had not failed me; rather, I had failed him by putting him in a role out of frame with his encodings. Furthermore, I felt somewhat responsible for his future; I did not want to see this wonderful young man start his professional life getting fired. So, I began making a series of iterative steps, testing him with different tasks that drew upon what I sensed to be his intellectual gifts, and he showed signs of flourishing.
