What the Dog Saw [147]
How should that ranking be done? Unfortunately, the McKinsey consultants spend very little time discussing the matter. One possibility is simply to hire and reward the smartest people. But the link between, say, IQ and job performance is distinctly underwhelming. On a scale where 0.1 or below means virtually no correlation and 0.7 or above implies a strong correlation (your height, for example, has a 0.7 correlation with your parents’ height), the correlation between IQ and occupational success is between 0.2 and 0.3. “What IQ doesn’t pick up is effectiveness at common-sense sorts of things, especially working with people,” Richard Wagner, a psychologist at Florida State University, says. “In terms of how we evaluate schooling, everything is about working by yourself. If you work with someone else, it’s called cheating. Once you get out in the real world, everything you do involves working with other people.”
Wagner and Robert Sternberg, a psychologist at Yale University, have developed tests of this practical component, which they call tacit knowledge. Tacit knowledge involves things like knowing how to manage yourself and others and how to navigate complicated social situations. Here is a question from one of their tests:
You have just been promoted to head of an important department in your organization. The previous head has been transferred to an equivalent position in a less important department. Your understanding of the reason for the move is that the performance of the department as a whole has been mediocre. There have not been any glaring deficiencies, just a perception of the department as so-so rather than very good. Your charge is to shape up the department. Results are expected quickly. Rate the quality of the following strategies for succeeding at your new position.
a) Always delegate to the most junior person who can be trusted with the task.
b) Give your superiors frequent progress reports.
c) Announce a major reorganization of the department that includes getting rid of whomever you believe to be “dead wood.”
d) Concentrate more on your people than on the tasks to be done.
e) Make people feel completely responsible for their work.
Wagner finds that how well people do on a test like this predicts how well they will do in the workplace: good managers pick (b) and (e); bad managers tend to pick (c). Yet there’s no clear connection between such tacit knowledge and other forms of knowledge and experience. The process of assessing ability in the workplace is a lot messier than it appears.
An employer really wants to assess not potential but performance. Yet that’s just as tricky. In The War for Talent, the authors talk about how the Royal Air Force used the A, B, and C ranking system for its pilots during the Battle of Britain. But ranking fighter pilots — for whom there are limited and relatively objective performance criteria (enemy kills, for example, and the ability to get their formations safely home) — is a lot easier than assessing how the manager of a new unit is doing at, say, marketing or business development. And whom do you ask to rate the manager’s performance? Studies show that there is very little correlation between how someone’s peers rate him and how his boss rates him. The only rigorous way to assess performance, according to human-resources specialists, is to use criteria that are as specific as possible. Managers are supposed to take detailed notes on their employees throughout the year, in order to remove subjective personal reactions from the process of assessment.
