Have you ever been driving and heard your inner voice tell you to take an out-of-the-way turn, only to find out there was an accident where you would have otherwise driven? Or met a new person and got a gut feeling not to trust them, which later proves true when you witness them betray a friend? This is what many refer to as having a “sixth sense.”
The mysterious concept of a sixth sense is more than just a spooky movie about a kid who sees dead people. Depending on who you ask, it has different meanings. And, like our other senses, it changes with age.
The sixth sense: gist, intuition and déjà vu
Some scientists consider the sixth sense as the ability to rely on a gut feeling or intuition to perceive something without sensory evidence. They say it’s often connected with both heightened awareness and intense instincts. Researchers describe this as a deeper connection to the subconscious. Or it can be the idea of a “gist,” as Laura L. Carstensen, professor of psychology at Stanford University and founding director of the Stanford Center on Longevity, describes it: “an advanced form of reasoning that is largely unconscious and develops with experiences.”
“You sort of get the general sense of something right, but are lacking details,” says Carstensen, noting that research suggests this ability can strengthen with age, allowing older people to size up a situation without needing to focus on every tiny detail. Age and experience help us find the signal and ignore the noise. In one study that Carstensen coauthored, older adults were less affected by negative emotions, which allowed them to make more accurate predictions.
Carstensen cites an example of additional research, where older physicians working in emergency rooms were observed as being able to better assess a patient and immediately sensed they needed urgent treatment, while younger physicians might rely on a checklist to reach the same conclusion. “It’s more a feeling like, ‘This is OK,’ or a feeling that ‘I need to do something about it,’” she says. More lived experience, adds Carstensen, likely fine-tunes this in older adults.
How Your Senses Change With Age
While episodic memory — the ability to recall details of memories — declines with age, gist can help to compensate. For instance, you may not remember exactly why you disliked a certain movie, but when a friend asks you to spend your Friday on the couch watching it, you’re able to save your evening by suggesting another film. Or when looking at a menu at a restaurant, you don’t need to remember that a dish had too much garlic, and that’s why you didn’t like it. Simply knowing it’s a pass is enough to save you from an ordering regret.
Carstensen says many older adults she works with often debate whether to make a geographical move or sign a lease at a senior housing community. “Sometimes they’ll say, ‘I didn’t like that place. And it’s not about the details,’” she explains. “They can’t retrieve all of that, but they can retrieve the sense of how they felt about it.” That sense of gist pertaining to how a place made them feel can serve as a surprisingly useful guide when making a big decision, she says.
But relying on gist does have caveats, as it can lead you to overlook specific details. Say you’re shopping for a car, and you instantly decide you don’t like the first car you step into. Later, when reviewing your options, you may decide heated seats are nonnegotiable. But when going back to that first model, you might be led to think it doesn’t have heated seats — when it in fact does — because you didn’t click with the car off the bat.
Unfortunately, our gut feelings don’t always serve us well. A recent AARP report found that 41 percent of American adults had money stolen due to fraud or sensitive information that scammers obtained and used fraudulently. Friendly people and lonely people are both more vulnerable to fraud. So before you part with any money, connect with someone you don’t know or start an online romance, double-check your instinct to dive in headfirst.
Carstensen’s advice? Trust your intuition, but verify where you can. “Gist can be wrong,” she says.
