Over the past eight years I’ve been studying the cognitive demands of physical work. That includes comparatively high-end jobs such as surgery and physical therapy, but mostly blue-collar and service occupations, such as plumbing and hair styling — the kind of occupations the people we just heard from hope to enter. Our society tends to make sharp and weighty distinctions between white collar and blue collar occupations, between brain work and hand work, “neck up and neck down” jobs, as one current aphorism has it.
But what I’ve found as I’ve closely examined physical work is its significant intellectual content. This content is no surprise if we consider the surgeon, but the carpenter and the hair stylist and the welder, too, are constantly solving problems, applying concepts, making decisions on the fly. A lot of our easy characterizations about work just don’t hold up under scrutiny. Hand and brain are cognitively connected.
