As the Democratic primary campaign heats up, the conversation is taking an unfortunate turn when it comes to discussion of candidates' ages. Late-night hosts such as Jimmy Fallon "joke" that Bernie Sanders, age 77, is sponsored by Metamucil and was present for the signing of the American Constitution. The pundits are hardly better than the comedians when discussing candidates' ages: In columns like these, they compare old age to a "shipwreck" and worry that "old duffers" are a danger to the republic.
As two humanists who study the culture of old age, we view such rhetoric as a distraction from serious issues and feel it reproduces inaccurate stereotypes about aging. One of the most important conversations we will be having in the 21st century concerns old age. The number of Americans over age 65 is going to double in the next 40 years, a demographic fact that opens up major questions about social support, care work and political economy.
An election season with a number of candidates over 65 could provide an opportunity for us to confront our unexamined prejudices against older people. And yet the mainstream media has done little more than circulate and reproduce the ageist stereotypes that physicians and activists have long been laboring to overturn.
The near-unanimous consensus of gerontologists in the past several decades has been that elderly people are more cognitively capable and adaptable than our prejudices indicate. The vast majority of people in their 70s do not show signs of dementia. While it is true that subtle cognitive decline is nearly inevitable for all of us, different sorts of intelligence are affected at different rates. Indeed, the effects of aging are far from homogenous or predictable, which is why we reject Robert Kaiser's recent suggestion that the risk of mental decline is grounds for disqualifying older candidates.
History shows that it is a dangerous game to politicize clinical data about a certain group's "intelligence" or capacity. Even if one did want to play that game, it remains to be argued whether the specific sorts of reasonably expected decline would lead to incompetence in the specific tasks of the modern American presidency - which are, to state the obvious, not the tasks replicated in the lab.
The question of whether elderly people are suited for executive office can be better answered with the tools of history. And history suggests that they are: South African leader Nelson Mandela, Britain's Winston Churchill and Konrad Adenauer, chancellor of West Germany for 14 years after the end of World War II, were all highly effective political leaders well into their 70s. Those worried about aging leaders might have in mind Ronald Reagan and Pope John Paul II, whose leadership capacity was affected by Alzheimer's and Parkinson's disease, respectively. We should remember, though, that neither of those diseases is especially common, and about 90 percent of the population over 65 is not afflicted by either.
The mismatch between popular ideas and scholarly research should not surprise us. History shows, too, that the devaluation of old age has more to do with culture and economics than it does with biology.
As recently as the 18th century, in the wake of the American Revolution, elderly people were valued as sources of wisdom and experience. This was an era before geriatrics and before "retirement": The notion that one exited the labor market at the age of 65 was unknown. Aging was certainly viewed as a form of decline, but it was also viewed as a naturally occurring process, to be welcomed and respected. Physicians who thought about old age, such as Benjamin Rush, wondered about how patients might achieve old age - not how old age and its infirmities might be cured.
