"I am not myself lately. Then again, was I ever? I'm not the self I
was a year ago, or the one I will be in five minutes. My sense of
reality is ephemeral, and my circumstances are constantly rewriting the narrative. My brain wants to make sense of all that, though, so it keeps trying to find order and actualization. But what it keeps writing, as Emory University psychology professor Gregory Berns puts it, is its own "historical fiction."
In his apt and timely new book, "The Self Delusion: The New Neuroscience of How We Invent — and Reinvent — Our Identities," Berns, author of "How Dogs Love Us," explores the neuroscience of self perception and the clever, confounding ways we attempt to tell the stories of our lives."
"The brain is a type of computer. In particular, I think, along with a
lot of neuroscientists, that it's fundamentally a prediction computer or
a prediction engine. That what brains evolve to do, which is try to
make internal models of how the world works so the owner of that brain
can survive and outwit competitors. Or if they're prey, to avoid
predators, always just staying one step ahead of things.
The better prediction that the brain does, the better the person or the
animal will do. There's been a strong evolutionary pressure to make
brains very good at anticipating things that might happen in the future."
"humans overlay it with a narrative on top so that we have a way of putting meaning on things, if you will.
The anticipation bit is not just about what's going to happen. It's
the consideration of the world of things that might happen. And not only
that. We also have the capacity to look back in time and imagine things
that might have been, the what-if scenarios. These are all various
forms of predictions that the brain has evolved to do, to help humans in
particular flourish in this world."
"we're going to be different in a year or ten years. We have to construct
some mechanism to link all these together. The way we do that is
through narrative and storytelling. We have to, just for our own
psychological health, construct something that links all these versions
of ourselves together. Otherwise, the alternative is completely
existential, that there is nothing unifying past, present and future,
and the universe is random. Psychologically, we can't handle that."
"our brains do not appear designed or evolved for continuous
recording, or at least recalling things in kind of a continuous fashion.
Our brains are not video recorders in the sense that a camera is. It
seems as if the memories themselves are laid down in an episodic fashion
and those episodes are defined by when things happen.
Most of the day, nothing happens. I don't think it's been calculated,
but we go through the day, probably 90% of the day is pretty static,
and then the other 10% is just stuff happening. That's going to vary
from day to day. When stuff happens, when something in the world changes
or something changes in you, those are the things that we encode in
memory and those are the things that get stored.
When you recall a memory, you can't call up the exact recording of
what happened. You have these sparse instances that you can call up. But
you still have to fill in the gaps somehow, because they're not just
still images, they're highlights. It's the highlight reel of the day, or
of your life."
"The brain has to fill in those gaps. The thing I've become fascinated about is, how do
you fill in those gaps? The best answer I have is that they're built on
what psychologists call schemas. Or if we want to be mathematical about
it, I call them basis functions. These are the templates that get laid
down early in life as children. These are the stories that we hear when
we're young, because those are the stories where the child doesn't have
many of their own experiences. Not much has happened. Those are the
templates for understanding the world, when the parents tell their kids
stories.
These are fairy tales and fables and simple stories, good versus
evil. These are going to be culturally different depending on where you
grew up, but there are some common themes. Importantly, those are the
templates that stay with us throughout our lives and help us interpret
these episodic events as they happen to us. They provide a ready
framework for slotting things into as they come."
"The brain is a prediction engine. It's that way because there was, at
some point in time, a survival advantage to that, and there still is.
If you think about the alternative, let's say that life is just a
series of random events that are completely unconnected to each other.
If that were the case, then there really wouldn't be any survival
advantage to having a predictive brain, because if things were random,
then there's nothing to predict.
The fact that we can predict things is also a reflection of the world
that we've evolved in, that there is some amount of order there,
certainly not 100%, but there's enough order that brains can extract it.
That drives things, even when there is no predictability or causality.
It's not like you can turn off the prediction engine; it's always going.
That's where superstitions come from. It's like if two events happen
in close proximity to each other, then the brain's naturally going to
equate them in some causal way, even if they're not. That's how
superstitions arise. Then you can consider superstitions the building
blocks of storytelling or fables."
"Self-identity comes from the story that you tell about your life, which
is the historical part. But it is a story. I hope to convince the reader
there isn't just one story for anything. That story is one that you
choose, and you have the capability of telling in different ways.
In that sense, it is fiction. The story you tell yourself is a sort
of fiction. It's almost a delusion. The story you tell about yourself to
other people is probably a slightly different version, so that's a
different fiction. This goes on and on.
I hope to convey in the book that the stories you choose to tell, we
have control over that to some degree. Actually, the best way to shift
your storytelling, if that's what you want to do, is by controlling what
you consume."
"For me, I don't feel beholden to my past self, if that makes any
sense. Some people have an ethos that they have a life purpose and then
they have to carry on a legacy. And for some people, it can be very
heavy. It might be passed down from generations.
I like to think that I've shed some of that; [sounds like Joseph Campbell quoting Nietzsche who said something like you must slay the dragon "Thou Shalt"] I'd be lying if I said
I've done it completely. I think COVID in particular has made us all
aware how short life really is. I've resolved to do what I want to do in
however many years I may have left on this earth [that sounds like following your bliss]"
