Speaker 1 (00:03):
You're listening to Why we Do what we do. Welcome
to Why we do what we do?
Speaker 2 (00:17):
Mini.
Speaker 1 (00:17):
I am your host Abraham and I'm Shane. We are
a psychology podcast. We talk about the things that humans
and non human animals do, and sometimes we talk about
proclivities that we have as a species that stand out
as being like kind of impressive that we can do
those things.
Speaker 3 (00:35):
Yeah, and so today we're talking about faces and how
much I like your face.
Speaker 1 (00:38):
Yeah, that's only part that's only half right. Yeah, although
I guess you could do the second part two. So
these are manyas we come out on Mondays. These are
short form discussions where we do a quick dive into
a topic and then we get out of there and
we try and pick things that we feel like we
can do justice too in like fifteen minutes or less.
We tend to know that if we say that something
(00:59):
will be short, it will be long. But this one
is short. I think it'll be short. I think we'll
do it in under fifteen. Maybe we'll even clock it
around ten. But just to pad out the run time
on this a little bit, I will say thank you.
Speaker 2 (01:09):
For joining us.
Speaker 1 (01:10):
If you'd like to support us, you can pick up
some merch leave us a rating and review, like subscribe,
tell a friend, or join us on Patreon, and I'll
elaborate on those a little bit at the end here.
I think that is what we have to say before
we launch into our topic. Our full length episodes come
out on Wednesdays, if I didn't say that already, and
this is a mini which is out on Monday, which
is hopefully when you're hearing it, but if not, then.
Speaker 2 (01:30):
Whenever you hear it, good for you. I hope you
enjoy it. I think that's it. So we're ready to
dive in.
Speaker 3 (01:36):
Yeah, let's do it.
Speaker 2 (01:36):
Okay.
Speaker 1 (01:37):
Many of us people, we report that we struggle to
remember names, very common experience, and that's not what we're
talking about. What we're talking about is that many of
us are, actually most of us are pretty good at
remembering faces. We will recognize faces very very well most
of the time for most people, not all of us,
and we'll talk about that. But for a lot of us,
(01:58):
we like, I know that person, I've seen them before
for and it turns.
Speaker 3 (02:01):
Out this might be a specifically human thing, or maybe
a cultural thing, or maybe a combination to the two.
So we can unpack this briefly, since this is a
mini and we're gonna get down to the answers of
why we can remember so many faces.
Speaker 1 (02:15):
And how many we can remember because humans can recognize
a lot a lot of faces and even recognize them
after having not interacted with them for like a very
long time.
Speaker 3 (02:27):
Yeah.
Speaker 1 (02:28):
So this is largely based off of a study that
was done that was like, this has been cited all
over the place.
Speaker 3 (02:35):
Yeah, for sure. So a twenty eighteen study in the
Proceedings of the Royal Society B which just rolls off
the tongue, Yeah, shows thousands of faces to twenty five participants.
If a participant could recognize the face twice, it was
counted as recognized. Otherwise it was considered unrecognized.
Speaker 1 (02:52):
So they essentially just then counted up how many faces
people could recognize. The lowest performer or performers recog about
one thousand faces of all the ones that they were
presented with. A thousand, Like, that's already a pretty big number.
Speaker 2 (03:07):
Yeah.
Speaker 1 (03:07):
The highest performers recognized upwards of ten thousand faces. Ten thousand,
that is ten times.
Speaker 2 (03:16):
More than a thousand.
Speaker 3 (03:17):
That's a lot of faces.
Speaker 2 (03:18):
That's so many.
Speaker 1 (03:20):
Most people averaged around five thousand faces, which is still
a huge amount of faces. That's just so so many.
Speaker 3 (03:27):
That's several faces. At least, it's so many.
Speaker 2 (03:30):
That's more than one.
Speaker 3 (03:31):
Yeah, it's at least more than one. Now, researchers did
accept the self reported recognition from the participants, so it
is possible that there was some bias in their answers.
And further, it is unclear if the super recognizers could
go above ten thousand and how high they could actually go.
So there was kind of like the self report comfound
and there was also the upper limit of the ten
(03:51):
thousand that we really don't know how far they could go.
Speaker 1 (03:54):
Yeah, I saw some I feel like I heard the
researchers in like oppress briefing or something specifically allude to
the fact that like they don't know if there's an
upper limit and what that upper limit is. Like the further,
super recognizers, like most people, it seemed like on average,
we're sort of capping out around five thousand faces, but
there are people where it's like they might just they
(04:16):
might recognize as many faces as they ever encounter in
a lifetime. Yeah, because that good. Now, one thing they
did find is that familiarity helped a lot, Like if
they were kind of already knew that face. That is,
if the participman already knew the face, they were quicker
and more likely to recognize that same face later because
they did use like a lot of celebrity pictures in here.
And Further, people who grew up in large urban areas
(04:40):
also tended to be stronger recognizing faces. And I think
it makes sense because these are people who are around
a lot more diverse faces a lot more of the time.
So whatever sort of muscle is being flexed here, they
were using that muscle a lot by sheer opportunity as
you know, kind of alone.
Speaker 3 (05:00):
Yeah, that makes sense. I would imagine growing up in
urban areas too, Like you're probably exposed to a ton
of ads, Like there's probably billboards everywhere, and like, you know,
the posters that are on the subways and stuff. So like,
I bet they're pretty good at recognizing those two just
like this one.
Speaker 1 (05:21):
All right, we're back. We're still talking about faces. Let's
see if we can understand why we're so good at faces.
Speaker 3 (05:26):
Yeah, so neural just love to point to the parts
of the brain that average greater blood flow when looking
at faces and point out that we seem to have
a specialized region for facial recognition. Indeed, we may also
struggle to tell non human animals faces apart, or at
least struggle to do so as easily as we do
with humans. But you know, we could still recognize some
animal faces.
Speaker 1 (05:46):
Yeah yeah, Like when exposed enough to certain animal faces,
we start to be able to tell those animal faces
apart from other animals of the same species, but without
that amount of time, Like we can see a face
once and be likely to recognize it later, versus with animals,
we might have to be around them for a long
time to actually be able to pick them apart from
other animals.
Speaker 2 (06:04):
Yea, and even then we.
Speaker 1 (06:05):
Might still struggle if they look pretty similar. So that
is the thing now understanding. The neurologists point here that
they see aggregated blood flow more in particular areas when
doing facial recognition tasks, and that's fine, that's the case,
that's what they found.
Speaker 2 (06:21):
At least.
Speaker 1 (06:21):
It is worth considering also that like we're exposed to
faces in social and emotional situations for the most important
parts of our lives and our survival from birth and onward.
So like the moment we come into this world, we're
basically oriented toward and surrounded by faces, and those faces
(06:42):
are necessary for our well being and survival and comfort,
and so we get a lot, a lot of practice
pretty much immediately. We start looking at faces most of
our lives, even before we're asked to then try and
remember faces for an experiment.
Speaker 3 (06:57):
Sure, yeah, that makes sense. I mean almost everybody encounter
growing up as a face almost almost. Yeah, there's always
an exception to the rule. Now, there are also people
who struggle to recognize any faces, and this is called
prosopagnosia prosopagnosia prosopagnosia obviously or face blindness.
Speaker 1 (07:15):
Yes, so like it's not universal. There are people for
whom this is not something that they can do very easily.
And that is actually a thing I've had on the
list to talk about for a long time, as prosopagnosia
and other like ephasia type things that people experience. But anyway,
that is a thing that is as true. But I
think it's fair to say, like we have certainly evolved
to be a highly social creature whose survival depends on
(07:39):
cooperation and group support. Being able to recognize at least
five thousand different faces is probably like overkill from an
evolutionary perspective, but like, sure, we get what we get,
and evolution produced the kind of eyes, brains, and behaviors
that we have, So like that's you know, we ended
up in this space as a product of evolution. It's
(07:59):
a thing that we can do, and it's definitely beneficial
for us, who are a very highly social creature, to
be able to do it. But yeah, I was just impressed,
Like five or ten thousand faces, that's so many. But
it does seem like, first of all, as I said,
we do this all all all the time. And second
(08:20):
like we are a cooperative species that depend on one
another for our survival and well being. And so even
though it doesn't feel that way, sometimes, particularly when you
have clowns who can go into power and tell us
that we should all be afraid of one another and
they're stupid and wrong, they might convince us that humans
are combative and they fight each other. And like, obviously
history has shown that we do fight each other in
(08:41):
many instances, but that's largely because the stupid people who
get into power and tell us that we should If
the smart people were in power, then we probably wouldn't
need to fight, because why would we. We're species trying
to survive and support the well being of our species.
So assuming that we could get on the same page
about that, at some point, we would probably not have
to have things like killing each other be a problem.
But anyway, that is getting way off on the side tangent,
(09:03):
which I knew would happen in any kind of format,
let alone a mini where I'm supposed to be constrained.
Point is, we are social. Therefore we are good at faces.
We seem like we're biologically prepared to be very good
at faces, and we spend pretty much our entire lives
doing good facial recognition stuff.
Speaker 2 (09:19):
Yeah.
Speaker 1 (09:20):
Perfect, I think we nailed it. Okay, we solved faces.
We solved it, We solved the faces, all right, perfect? Well, great,
glad we came in a reasonable amount of time on
that one. Is there anything that I miss or you'd
like to add before we get to our credits really quick?
Speaker 2 (09:31):
No, I don't think so. Great.
Speaker 1 (09:33):
As I mentioned, to support us, if you like what
we're doing. If you like what we're doing, I make
sure that part's clear, go over and leave us a
rating and review, make sure that we support it, gets
other people's feed, that sort of thing.
Speaker 2 (09:43):
We really appreciate it. It helps us out.
Speaker 1 (09:45):
You can also tell a friend go just grab the
phone and subscribe to us, put stickers on things whatever.
Speaking of which, you can pick up things at a
merch store. That helps us a little bit. You can
join us over on Patreon, where you'll get behind the
seats content, ad free content, early episodes, that sort of thing,
and I will read the list of names and supporters
that we have at the end of our full length
discussions every single week. Those names get recognition because we
(10:07):
really appreciate who those people are, who they have been
for us, and everything that they do. So if you
would like to have that happen for you, you can
do that. And as I said, get ad free episodes.
Our ad segues are fun, but they're still full of ads,
so you can go get them with just the ad
segues and none of the ads, and that's just the
best of both worlds.
Speaker 3 (10:25):
That's fun.
Speaker 2 (10:26):
You can just hear that blank spot exactly.
Speaker 1 (10:28):
You can also tell us your thoughts, experiences, and arguments
you have for and against our facial recognition stuff. You
can email us directly at info ATWWDWWD podcast dot com,
or reach out to us on the other social media platforms,
particularly active on Blue Sky, but we got other things
going on there and other places as well. Thank you
so much to my team of people who help make
this podcast happen. Writing in fact checking from Shane and myself.
(10:51):
Thank you for recording with me today, Shane anytime. Our
social media coordinator is Emma Wilson, and our audio engineer
technician person who does all the good sounds is thank
you justin Yes, we love him and Emma, thank you
all for listening. I think that is what we have
to say before and then we can wrap this one up.
Speaker 2 (11:07):
Is there anything you'd like to add? Nope?
Speaker 1 (11:09):
All right, go out and look at faces. This is Abraham,
this is Shane.
