Aging brains make seniors vulnerable to scams

[2017]

TLDR:

>About 45 million Americans were age 65 and older in 2013, according to the U.S. Census Bureau.

>Spreng and his team evaluated 13 older adults who had been robbed by family members or neighbors, or scammed online or by phone. The researchers compared that group to 13 peers who’d been exposed to a potentially exploitative scheme, but recognized and avoided it.

>Larger studies are needed to confirm these findings and perhaps identify markers -- both biological and behavioral -- to identify who’s most at risk of scams, Spreng said.

I understand that studies cost money, but deriving anything from a study on 13+13=26 people seems to me a bit hasty.
