MICHIO KAKU: We still have Flat Earthers,
we have people that don't believe in vaccinations,
and what do we do about it?
Well, first of all, I think there's a gene.
I think there's a gene for superstition, a
gene for hearsay, a gene for magic, a gene
for magical thinking.
And I think that, when we were in the forest,
that gene actually helped us.
Because 9 times out of 10, that gene was wrong.
Superstition didn't work.
But 1 time out of 10, it saved your butt.
That's why the gene is still here, the gene
for superstition and magic.
Now, there's no gene for science.
Science is based on things that are reproducible,
testable -- it's a long process, the scientific
method.
It's not part of our natural thinking.
It's an acquired taste, just like broccoli.
You have to learn how the power can be unleashed
by looking at your diet, for example.
So I think 1,000 years from now, 1,000 years
from now, we will have Flat Earthers.
A thousand years from now, we will have people
that still do not want to be vaccinated.
OK?
So what do we do about it?
Well, it's a struggle.
It's a struggle that's eternal, because I
think it's part of our genetic makeup.
And there's even a name for some of this superstition.
It's called pareidolia.
What is pareidolia?
It's the idea that when you look in the sky,
you see things that are not there.
Here's one experiment: Look at the clouds
and try not to see something there.
It's very difficult.
You look at the clouds.
You can't help it.
You see Donald Duck.
You see Mickey Mouse.
You see snakes, animals.
You see all sorts of stuff.
You can't help it.
Recently, the Notre Dame Cathedral partially
burned down.
And sure enough, somebody said, 'I see Jesus
Christ there.'
I saw the picture.
Maybe you did, too.
It really did look like Jesus Christ.
But it was the ashes of Notre Dame.
And how many times do people see the Virgin
Mary in a glass of tea?
So we are hardwired to see things that are
not there.
Because for the most part, they're harmless.
For the most part, they do nothing.
And once in a while, it saves our butt.
And so that's why I think we will have Flat
Earthers, we will have the people who don't
like vaccination, because hearsay throughout
human history was the dominant form of information-sharing.
You know, the internet is very new.
Newspapers are very new.
Science and technology is very new.
But gossip, hearsay, slander, rumors, there's
a gene for that.
OK?
So how do you combat it?
Slowly, carefully, painfully -- it's a painful
process, but in some sense, we're going up
against our genetic predisposition to believe
in nonsense.
