Picking a subject from his upcoming book, Malcolm Gladwell talked about the difficulty in hiring people in the increasingly complex thought-based contemporary workplace. Specifically that we're using a collection of antiquated tools to evaluate potential employees, creating what he calls "mismatch problems" in the workplace, when the critera for evaluating job candidates is out of step with the demands of the job.
To illustrate his point, Gladwell talked about sports combines, events that professional sports leagues hold for scouts to evaluate potential draftees based on a battery of physical, psychological, and intelligence tests. What he found, a result that echoes what Michael Lewis talks about in Moneyball, is that sports combines are a poor way to determine how well an athlete will eventually perform as a member of their eventual team. One striking example he gave is the intelligence test they give to NFL quarterbacks. Two of the test's all-time worst performers were Dan Marino and Terry Bradshaw, Hall of Famers both.
A more material example is teachers. Gladwell says that while we evaluate teachers on the basis of high standardized test scores and whether they have degrees and credentialed training, that makes little difference in how well people actually teach.
