Contrary to conventional wisdom that cognitive function declines beginning in the mid-forties, aging does not correlate with deteriorating ability to think for ourselves. These are the findings of “Healthy Brain, Healthy Decisions: The MetLife Study of Decision-Making Potential,” one of the first projects to investigate the connection between cognitive health, aging and decision making capacity. The research was conducted with men and women in their 50s, 60s and 70s by the MetLife Mature Market Institute and the Center for BrainHealth at The University of Texas at Dallas. The study demonstrates that age alone is not a key factor in predicting the ability to make decisions.
Focusing on healthy adults in their 50s, 60s, and 70s, the researchers found that those who demonstrated smart decision-making also excelled at strategic learning—the ability to sift more important information from the less important.
Although study participants in all three life stages had about the same strategic learning abilities, the oldest participant group slightly surpassed the rest, implying strategic learning capacity may actually increase with age in normally functioning adults.
Additional findings show that older study participants (those in their 70s) were more conscientious, remained vigilant (i.e., considered their options before making a decision) and avoided being hyper-vigilant (i.e., focused on immediate solutions without considering other outcomes) when compared to the younger group (those in their 50s).Researchers gauged participants’ financial conscientiousness (i.e., being careful and organized) using a series of questions regarding monthly budgeting practices and financial retirement plans. The full study, along with consumer tips Is Your Decision-Making Style Healthy?, is available here. The Healthy Brain, Healthy Decisions project contends that previous large sample studies documenting declines in the ability to think logically and solve problems, starting as early as age 40, fail to identify individual factors which contribute to declining decision-making capacity, such as early dementia or other medical causes. Moreover, they ignore such positive age-related aspects as extensive life experience, reasoning ability and accumulated knowledge that may preserve or even enhance decision-making. “Combining these findings with emerging evidence of retained cognitive brain health in aging suggests that policies aimed at protecting those most vulnerable to poor decision-making should focus on impairment caused by an underlying medical condition, rather than age itself, as a risk factor,” said Sandra Timmermann, Ed.D., director of the MetLife Mature Market Institute . “Rather than attributing impaired decision-making to age alone, approaches that assess an individual’s strategic learning ability and cognitive function can improve our understanding of decision-making capacity at all ages and between genders.” “The study findings are a crucial first step to move beyond age as a demographic factor used to explain impaired decision-making,” said Sandra Chapman, Ph.D., founder and chief director of the Center for BrainHealth at The University of Texas at Dallas. “Policies and practices that focus exclusively on age-related declines in decision-making will unnecessarily curtail the autonomy of older adults with preserved cognitive function. Age is not a disease, therefore noticeable drops in mental decline warrant medical attention to determine cause and best course of action. Maximizing cognitive potential is possible across the lifespan.”
