There’s a reason so many older people fall for financial scams, new research suggests. They don’t respond as readily to visual cues that suggest a person might be untrustworthy, and their brains don’t send out as many warning signals that ignite a danger ahead gut response.
The research, published Monday in the Proceedings of the National Academy of Sciences, is the first to show that older adults’ vulnerability to fraud may be rooted in age-related neurological changes.
Specifically, researchers from the University of California, Los Angeles, found that an area in the brain known as the anterior insula was muted when older people looked at photographs of suspicious-looking individuals. This part of the brain activates gut-level feelings that help individuals interpret the reliability of other people and assess potential risks and rewards associated with social interactions.
In one part of the U.C.L.A. study, both younger and older adults were asked to evaluate the trustworthiness of people portrayed in 60 photographs while undergoing brain scans. When the younger adults (21 altogether, from 23 to 46 years of age) labeled a person “not trustworthy,” their anterior insulas lit up. But this wasn’t true for older adults (23 altogether, age 55 to 80).
“The warning signals that convey a sense of potential danger to younger adults just don’t seem to be there for older adults,” said Shelley Taylor, the lead researcher and a psychology professor at U.C.L.A.
In another part of the study, researchers asked 119 older adults (55 to 84 years old) and 24 younger adults (age 20 to 42) to rate people in photographs as trustworthy, neutral or untrustworthy. Signs they were potentially untrustworthy included people with insincere smiles, averted gazes and postures that “leaned away” rather than toward the camera, among others, Dr. Taylor said.
Older adults were equally adept at identifying people judged to be trustworthy or neutral, but much more likely to miss signs of those who may be untrustworthy and view suspicious-looking people as approachable, the study found.
“We believe what’s going on is that older adults have a bias toward positive emotional experience and this keeps them from recognizing negative cues,” Dr. Taylor said.
This so-called “positivity effect” has been documented through research by Laura Carstensen, a professor of psychology and public policy at Stanford University, and it explains why older adults are, on the whole, happier than younger adults.
Asked to comment about the new study, Ms. Carstensen said in an e-mail that it was “very well done,” and observed that for older adults, “there are likely many benefits of looking on the bright side. However, there are likely some contexts where looking away from the negative and focusing on the positive is not good,” including financial scams and fraud.
Alexander Todorov, a professor of psychology at Princeton University, called the findings “interesting,” but warned that “there is an implicit assumption that these trustworthiness evaluations based on facial appearance are accurate. This is far from clear.”
Dr. Taylor became acutely aware of financial fraud practiced on the elderly almost 20 years ago when her elderly father handed $17,000 to two men who approached him on the street and walked with him to his bank.
“I got descriptions of the two men from someone who lived nearby — one had few teeth, both were dressed in a slovenly manner, and they’d been seen sleeping in doorways and were using the drug rehab center nearby,” the professor explained in an e-mail.
In other words, they would have been viewed skeptically by most people, but weren’t seen in that light by Dr. Taylor’s father.
Statistics show that financial exploitation of the elderly is on the rise. According to a study published last year by the MetLife Mature Market Institute and the National Committee for the Prevention of Elder Abuse, elder financial abuse — everything from fraudulent sweepstakes to bank accounts emptied out by guardians — totaled $2.9 billion in 2010, a 12 percent increase from only two years before.
Earlier this year, the Government Accountability Office weighed in on the issue, noting the inadequacy of existing safeguards and calling for a new national strategy to address the problem.
On Tuesday my colleague Paula Span wrote about a just-published consumer guide, “Protect Your Pocketbook,” intended for older adults and families who wanted to understand what put them at risk, how to prevent fraud, and where to turn for help.
As for Dr. Taylor, she advises that seniors never agree on the spot to a phone offer or a pitch from a door-to-door salesman. “Either hang up or wait and get someone else involved in your life to evaluate what’s being presented,” she said.
With financial fraud, almost half the time seniors end up being taken in by a caretaker or someone posing as a friend. “Make absolutely sure that you’ve carefully checked out the people taking care of an older relative,” or any “surprising new friend” that you’ve never heard of before that’s now on the scene, she tells family members.
