I'm here to talk you today about nightclubs,
which I've spent the better half of this decade
kind of living within them.
And what is important about them is that you observe people behaving
with that certain kinds of pressures
and how that scales out to the outside world.
So, first of all: what is a nightclub?
Nightclubs have been around for about forty, fifty years maybe,
and they are relatively small rooms, you are filling it with this species
that's been evolving for millions and millions of years,
so, in terms of evolutionary time, that's a really short sliver.
And when you apply certain variables to people, they act in certain way.
They only exist in highly urbanized metropolises,
and although they sell alcohol, the real commodity that a nightclub sells
is actually sex and social status.
Because of that, they are catered towards men,
which is why the gender issue is skewed, it's always
sixty percent women to the forty percent men in a night club
And most importantly, there is a door policy.
It is one of the only businesses in the world where they can just refuse entry
based on whatever, what you look like,
if you're not dressed appropriately, etc.
And so, there is a couple of variables
that go into a nightclub:
the first is music and lighting,
which, in fact is that at the sensory level, it's data coming in
through our eyes and through our ears.
The next is drugs and alcohol, which affects perception,
so not only how you're perceiving the night,
but also how the memories are physically being encoded
and how you're going to remember it later on.
And then, sex and social status
which are the commodities that we discussed before,
there is a difference as a social rules, so if you wanted to
walk up to somebodyone and initiate a conversation,
then you can do that, but you might not
feel comfortable doing that in a place like a grocery store.
There is also a different set of laws within them,
because the immense social power
and influence and the amount of money
and overall wealth in these clubs,
these people can kind of get away with whatever they want.
So laws are broken all the time,
and nobody really gets in trouble for anything.
So, my passion is music,
because music is cross-cultural,
it's been in every single society and civilization,
that's known to man.
You'll be hard pressed to find someone that you know
who doesn't listen to any sort of music at all,
and because of that, in terms of natural selection,
it means it was selected for.
So basically, if you liked music, you lived to pass on your genes to your offspring,
and if you didn't like music, well you died and didn't pass your genes on.
So, we have our biology and sociology,
and they're constantly at war pushing against each other,
but the interesting thing about alcohol is,
as a chemical, we don't really know how it works,
but one of the effects is disinhibition.
It makes people more outgoing and louder.
It does this by removing the top level
or the more recent cognitive processes that evolved.
So we evolved these certain hard wired traits,
that are meant to keep us safe,
but alcohol removes these traits,
like etiquette and our biology takes over.
So when I say a nightclub is stereotypically the most dishonest
business that you can get into, it's true,
but the irony in that statement is that people actually behave
really really honestly once they are inside them,
so it's just an interesting lens to look at society through.
So, in exposing the primitive drives,
there is food, water, sex and aggression.
So, with alcohol unless these social norms holding us back,
it's exposing more or less these biologicaly
primitive drives from the oldest part of our brain,
they call it "the lizard brain."
So food: after the bar, typically people go and get a burger,
nobody really craves a salad that late at night
after they have been drinking,
and that's because evolution selected for us
to opt for the carbohydrates and fats, because they have more energy,
and it's enhancing your likelihood of survival.
Water is kind of taken out of the situation,
because everybody is drinking all night.
Sex, when I say that more sex happens after a nightclub
than in any other business around the world,
it is not an understatement.
And aggression, when you take a look at stats,
that over 50 percent of violent crimes are committed
under the influence of alcohol, you can see why.
Another thing is called "the rock star effect",
which is really important when it comes to nightclubs and any kind of music.
The "rock star effect" is the release of oxytocin during singing.
Oxytocin is a hormone that produces feelings of trust and ove in humans.
It's released by both sexes during intercourse
and makes pair bonding as a way of increasing the likelihood
essentially that the father is going to stick around
so that if a baby is born,
that there is two people to raise it
instead of one, because having two parents to raise the offspring,
drastically increases the survival than having one parent.
Dr Paul Zack just spoke about oxytocin at TED Global
and his lab showed that it wasn't only responsible
for trust and love, but for morality,
and morality is something that makes us human.
So we are the only creatures that listen to music,
and we are the only creatures with any sort of morals,
and these all kind of revolve around this hormone oxytocin,
so there is something really special about that.
And because oxytocin is releasing these feelings of trust,
morality and love, which are all high demand
by mates and members of the opposite sex,
that's the reason why you hear people
wanting to sleep with the lead singer of the band
or thousands of girls crying over
Justin Bieber every day.
It's also one of the only things that can put
a 100.000 people in one place at a time,
music festivals can easily attract these kinds of numbers, like Coachella.
It is also the reason "American Idol" is
one of the most watched television shows of all time,
and why guitar hero outsells like every other video game.
It's because the music and the emotional attachment.
So I'm going to play a couple of songs for you now.
Every song has a bunch of fundamental characteristics:
there is tempo and key.
So tempo is the speed in beats per minute
that a song is playing at,
and key is either minor or major,
and even an untrained ear can tell you
that minor key sounds sad,
and major key sounds happy.
So, I'm going to play two samples for you right now
and I want you to listen and be able to tell me
which one is the happy sounding one.
(Piano music)
So that was number one.
(Piano music)
So, who thought number one
was the happier sounding sample?
OK so that is the entire room,
so that's your proof that everybody can detect emotion within a song,
which is really important, because nobody is trained to do that,
yet, somehow we are able to.
So, right around the time of the 2008 recession
I was playing in this club,
I was a DJ for a while,
and I knew this room inside and out.
I knew what people wanted to hear,
I knew what kind of styles they wanted,
and my job is to play the music that they want,
and to not play the music that they don't want,
that's what makes an effective DJ
You have to read the room, you can't play for yourself.
So, week after week I saw these people,
then the stock market crashed
and for two weeks nobody was going out,
they said, "Don't even bother coming in to work."
And the week after I went in,
and it's the same people, the same faces,
but they were not into the same music that was going on two weeks ago,
they wanted this fast paced electro music.
Which is when a lot of you probably listened
to electro out there, which used to be an underground genre,
and it broke through to the main stream.
And one of the characteristics of electro is that
it's has actually a lot of minor keys.
And so it sounds sad to everybody, even an untrained ear.
So I texted all my other buddies that were DJ-ing,
in New York, Toronto or Los Angeles,
they all said the same thing was happening,
so, there was something more at work.
And so, what I did was: I took the Down-Jones industrial average
as an index of the stock market,
but also as a way of measuring how people feel, kind of globally.
And I cross referenced that with every hot 100 track
that had ever touched ground on the billboard charts,
and I classified it by tempo and key.
But essentially, to 87 percent accuracy,
the stock market was dictating what was hot on popular charts.
So economic busts were associated with up tempo,
and sad sounding music, minor keys,
whereas booms were associated with down tempo and major keys,
to such a highly statistical number
that it just had to be true.
So, you have a correlation there,
you don't necessarily have the causality
and they are not always the same.
So, we are going to go into the causality.
If you think of money, as resources,
which affect our mood, our friends' moods,
and it affects global moods,
under times of stress, we have a fight or flight response,
which is basically: if you're walking down the street,
and a bear pops out,
you have to decide whether or not you're going to run,
it releases a bunch of neurotransmitters
like adrenaline, and natural pain killer,
so that whether you're fighting or running, it's the same response.
So, when we're under this kind of economic stress
which is literally challenging our survival,
these same chemicals are peculating into our brain at a smaller rate
so we're not having panic attacks,
but if you remember how you felt during the time of the recession,
people were for sure a little more on edge.
So just to reiterate:
economic booms were happier, and the music is slower, more relaxed.
Economic bust, were a little bit more on edge
and the music sounds faster and sinister.
So this goes into resource theory,
which affects every single mammalian model in the world
and a lot of other insect species and aquatic.
But it has to do with men competing for access to females.
So in terms of mate selection, the number one thing
cross-culturally that men look for in a woman is good looks
and the number one thing cross-culturally
that women look for in a man is access to resources.
It's superficial and shallow but there are countless studies
that prove that, so that is what the data says.
And, so we can see that this kind or resource theory
in other societal projections.
So "less is more."
If you understand this, you'll understand a lot about human behavior,
but it's basic supply and demand.
When demand increases,
supplies goes down and the price goes up,
the more expensive something becomes,
the less people can afford them,
and so, by wearing those things they are sending
a very specific message to the outside world.
So this is how the economy influences fashion trends.
So, this is called the "Hemline Index."
It was originally uncovered by George [Taylor] in 1926
and then reaffirmed in 2010 by Ben Bourguee in France.
But you would think that the dress on the far right
is the least expensive
when actually, it's the most expensive.
And you're getting the least amount of material,
so it doesn't really make sense, it's illogical.
Dresses were short during the recession,
and so it didn't really make senses that you are paying more for less,
but then, when you start to think of
how fashion trends actually pick up,
today's fashion was designed at least one,
but probably two or three years ago,
so dresses were short during the recession
because of the 2005, 2006, economic boom,
so it cost more to wear less,
and we can see that in times when the economy is like that.
This right here is called a "scent pyramid".
So for any kind of fragrance, like perfume or colon,
you have bottom notes, middle notes and top notes
and they are all different in volatility,
how quickly they will evaporate once they are sprayed on,
And they all react with your skin chemistry differently.
So during times of economic boom and busts,
the scent chemistry actually changes.
So during booms, it is the small really expensive
really noticeably smeling Kim Kardashian bottles,
and during bust, it is the larger bottles,
more classic scents, like Chanel N°5.
So basically, during economic bust
again we see that people want to get more value out of it,
and during booms people want to spend more money on less value.
So I wanted to point this out just to show
that it is not only guys who act like this but girls act like this too.
And then again back to "less is more".
It is a basic principle of supplies and demand,
the ability to show that you can pay a lot for something
sends a very specific reproductive signal.
It puts you in high demand.
So why is all this stuff important?
Well, as different and unique as we try to be,
we actually all have a lot in common.
We have these hard-wired biological traits
that fight against societal norms on a constant basis,
they are so ingrained in our biology, in our psychology,
in our day-to-day lives, that we don't even notice them.
So, the take home message is that it's really important
to know where we came from, so we can see where we're going.
Thanks for your time.
(Applause)
