If you want your memory to stay strong, you probably already know what to avoid -- excessive alcohol, beating your head on things, getting any older. What you probably didn't know is that there are other, lesser known everyday threats that may be slowly turning you into that guy from Memento.
Between now and Election Day, you're going to see a variation of the ad below from dozens of candidates, several million times. The candidate will talk about how we need to bring back the America of the past, and you'll see images of 1950s-style white picket fences:
... post-war era storefronts:
... and maybe even the Old West:
Remember the good old days of living in filth and getting trampled by cows?
Those are all from a current ad for Newt Gingrich's presidential campaign, but you've seen variations of it from every politician who has run for office since television was invented. The ads are aimed at older voters, and all hit the same button: "Don't you vividly remember how much better things were before?" It's not just politics, either -- around the holiday season, watch how many ads hammer the "Remember how great Christmas was when you were a kid?" message, like this Acura ad that cuts from happy kids opening presents to an adult buying a new car. The tagline: "The joy is back."
Well, those nostalgic ads work because they can not only make you remember the past, but can totally plant fake memories in your mind. The reason your grandpa remembers the 1950s as nothing but friendly neighbors and soda fountains is because ads and TV shows have been hammering his brain with those images for five straight decades.
Ah, the atomic age was the best!
Science has proven it; we described once before an experiment in which scientists were able to convince a bunch of people that they had met Bugs Bunny at Disneyland as children, just by describing the event to them. Participants were suddenly able to "remember" all the details, despite the fact that there has never been a Bugs Bunny at Disneyland, not unless Bugs got very lost (he's not a Disney character, for those of you who haven't caught up).
Advertising works the same way. Researchers did another study where they had a group of people watch a series of advertisements that described the experience of eating a popcorn product that the scientists just made up. Half of the participants were then fed this so-called brand of popcorn (which obviously didn't exist and was hopefully called Falsepop). The rest had to make do with cucumber sandwiches or whatever scientists usually serve for lunch.
When grilled about the experience just one week later, those who had seen the most vivid commercials were just as likely to remember actually having eaten the popcorn, whether they actually did or not. Think about that for a moment -- whether or not they actually ate the popcorn was not as important as how convincingly some advertising executive told them they had. And this wasn't months or years later -- it was seven freaking days.
The experiment was testing a theory of memory known as reconsolidation -- in short, the idea that our memories are not fixed and static, but can be altered and updated based on what our brain thinks is helpful new information. If you vaguely remember that your first grade teacher's hair was black and somebody shows you a photo proving it was brown, you will actually update your memories to remember it as brown ... even if the photo is a fake. We didn't just pull that example out of our asses -- a simple Photoshopped image was enough to convince test subjects they had taken a hot air balloon ride as kids, even though they'd never set foot in one.
"And that's how your mother died."
And while we're focusing on incredibly disturbing things ...
