The abstract of a study by Lauren Hersch Nicholas for the Center for Retirement Research at Boston College:
We use Health and Retirement Study data linked to the Department of Labor’s O*Net classification system to examine the relationship between lifetime exposure to occupational demands and retirement behavior. We consistently found that both non-routine cognitive analytic and non-routine physical demands were associated with worse health, earlier labor force exit, and increased use of Social Security Disability Insurance. The growing share of workers in jobs with high levels of cognitive demand may contribute to growth in DI use.
It's obvious at ground level that people who work at jobs that have higher physical demands have higher rates of disability. It only stands to reason. However, increased rates of disability for those in jobs requiring the use of higher "cognitive analytic" skills comes as a surprise. I'm generally skeptical of government funded research that ends up calling for more government funded research. This report actually doesn't make that recommendation but this is a topic worthy of more research.
