the period he studied, English and Welsh students had to specialize before college so that they could apply to specific, narrow programs. In Scotland, on the other hand, students were actually required to study different fields for their first two years of college, and could keep sampling beyond that.
In each country, every college course that a student took provided skills that could be applied in a specific field, as well as information about their match quality with the field itself. If students focused earlier, they compiled more skills that prepared them for gainful employment. If they sampled and focused later, they entered the job market with fewer domain-specific skills, but a greater sense of the type of work that fit their abilities and inclinations. Malamud’s question was: Who usually won the trade-off, early or late specializers?
If the benefit of higher education was simply that it provided skills for work, then early-specializing students would be less likely to career switch after college to a field unrelated to their studies: they have amassed more career-specific skills, so they have more to lose by switching. But if a critical benefit of college was that it provided information about match quality, then early specializers should end up switching to unrelated career fields more often, because they did not have time to sample different matches before choosing one that fit their skills and interests.
Malamud analyzed data for thousands of former students, and found that college graduates in England and Wales were consistently more likely to leap entirely out of their career fields than their later-specializing Scottish peers. And despite starting out behind in income because they had fewer specific skills, the Scots quickly caught up. Their counterparts in England and Wales were more often switching fields after college and after beginning a career even though they had more disincentive to switch, having focused on that field. With less sampling opportunity, more students headed down a narrow path before figuring out if it was a good one. The English and Welsh students were specializing so early that they were making more mistakes. Malamud’s conclusion: “The benefits to increased match quality . . . outweigh the greater loss in skills.” Learning stuff was less important than learning about oneself. Exploration is not just a whimsical luxury of education; it is a central benefit.
It should come as no surprise that more students in Scotland ultimately majored in subjects that did not exist in their high schools, like engineering. In England and Wales, students were expected to pick a path with knowledge only of the limited menu they had been exposed to early in high school. That is sort of like being forced to choose at sixteen whether you want to marry your high school sweetheart. At the time it might seem like a great idea, but the more you experience, the less great that idea looks in hindsight. In England and Wales, adults were more likely to get divorced from the careers they had invested in because they settled down too early. If we treated careers more like dating, nobody would settle down so quickly.
For professionals who did switch, whether they specialized early or late, switching was a good idea. “You lose a good fraction of your skills, so there’s a hit,” Malamud said, “but you do actually have higher growth rates after switching.” Regardless of when specialization occurred, switchers capitalized on experience to identify better matches.
Steven Levitt, the economist who coauthored Freakonomics, cleverly leveraged his readership for a test of switching. On the “Freakonomics Experiments” home page, he invited readers who were considering life changes to flip a digital coin. Heads meant they should go ahead and make the change, tails that they should not. Twenty thousand volunteers responded, agonizing over everything from whether they should get a tattoo, try online dating, or have a child, to the 2,186 people who were pondering a job change.* But could they really trust a momentous decision to chance? The answer for the potential job changers who flipped heads was: only if they wanted to be happier. Six months later, those who flipped heads and switched jobs were substantially happier than the stayers.* According to Levitt, the study suggested that “admonitions such as ‘winners never quit and quitters never win,’ while well-meaning, may actually be extremely poor advice.” Levitt identified one of his own most important skills as “the willingness to jettison” a project or an entire area of study for a better fit.
