Jobs that require social skills are growing faster and paying more than ones that do not require social skills. Business is not a ‘one-person’ endeavor. Occupations that require strong social skills have grown much more than others since 1980, according to new research. And the only occupations that have shown consistent wage growth since 2000 require both cognitive and social skills. The findings help explain a mystery that has been puzzling economists: the slowdown in the growth even of high-skill jobs. The jobs hit hardest seem to be those that don’t require social skills, throughout the wage spectrum.
