Many people have tried to explain the sudden drop in crime in basically in the
nineties in new york city a lot of people given the credit too
efforts that word were done to crack down on my paid crimes in the ideas that
that would then lead to other crimes being less common
and certainly crime especially violent crime rates to go down
during the nineties in subsequent years in new york city
uh... but
uh... further research that was done uh... by other people i'd that i think
is much more interesting much more compelling tried to explain why in many
other cities that didn't have similar approaches to actual crime fighting
you also saw huge reductions
in rates of violent crime like we see dallas fell seventy percent in the
nineties newark seventy four percent loss angeles seventy eight percent which
is crazy
violent losses police have been before we got here
and so that night is that if they did not know i'll have those attempts to
crack down on paper executive explanation
and so one that we're gonna talk about right now is the idea that earlier all
in the on
lead in the atmosphere
uh... was contributing to up as infants grew up it would affect their brains in
way that in ways that they would be more violent when they got older
and the idea is that once we crack down on the lead both in paint ending in a in
gasoline
it was less common in the atmosphere
children were growing up that were as exposed to lead and work that's
predisposed to violence and now we're reaping the benefits of that and we can
go to end up in the study we really get
uh... it's uh... an article that was written on a mother jones what do you
think about this you think it's possible that
that led to is the actual reason that violent crime has been
virtually wiped out
so uh... this is really interesting to me because actually before you send this
article today i stopped the operas on
a podcast called majority report was sincere and i almost place until
yesterday and now i wish they would have to have come by after and so
the guy reaction to this is it just sounds some implausible
off the top
because the wind cripple would lead to possibly highs violent crime those two
things as don't seem like things
that would wake up on the night don said this is a very long study it's it's but
it it is very interesting it's it gets rained out from his mother jones article
citizen in europe quick quick quick sum up basically
after doing it years and years and years worth of research
they found that it's basically a reversal you car
for the amount of what matters here at the amount of violent crime
and they match how that would look so they grab what will you explain this the
favor stratosphere the area
seven matchup
pretty pretty closely but there twenty years off
and the reason that they are twenty years off of each other is because
they're committing these violent crimes and so i think one thing that is
important
so mine itself sounds a little bit far-fetched to be obsolete off the top
to me it led led would affect the brain or know that led up what caught violent
crime aka however when you put it that way that lead affects the brain and then
the yes of course to me that makes much more sense because basically what you
have been as i could just talking to one of our producers lucas about this
earlier
is that what you have this the
it's not necessarily causing you to be violent but it's affecting your brain
itself it's uh... reducing your i_q_ elements of that you want more explains
scenarios that here's
that you talk about this is a so basically this is showing a correlation
between blood lead levels
uh... in children deserve younger than sex and the effect that it has a night q
uh... and you know what you're seeing charted there is the average blood lead
level and so uh... as you implied and i apologize sometimes i talk about these
studies icing that the people watch the video are gonna do the research into
review articles but often reading the comments are as it's not the case and so
the most basic thing is that all of you say the researchers took into account
people assume leading integrating brewed cup
but also would like to go to little instantly tell a person
dot that was up about
begin this research over decades exited in multiple states in the u_s_ in
multiple countries and they showed the correlations
and different countries reduce their their quality of lead
in people's brains in the atmosphere at different times but he still saw the
person correlation
uh... you can even be did in in this article they showed
different neighborhoods in uh... a new orleans and they showed how even bear
the differences in blood lead level and violent crime correlated to the
neighborhood level and explain that one reasons he saw more violent crime in
cities around the world areas
was that
uh... there's a a greater concentration of cars in small areas and so the
atmosphere uh... lead level was higher there
as i know that this is really technical and we don't have time unfortunately to
do
real justice to how in depth this research was and how many different
studies were done
but i think that in this time where people are actually thinking about
violent crime again because of all these mass shootings
it's interesting to to at least consider the possibility that
something that we never considered like this toxin in the environment right
could be causing right
i think it's a it's a hot mess that will add is toxic that's not that's not
really up for debate you know
if you live in an apartment that was bill early on in the seventies you have
to sign something saying okay i know that there is a big big across that
there's lead paint his apartment yeah obviously wetpaint not if not legally
more so obviously a ladder
has a very negative side effects and one thing that i do images quickly on the
night of a keogh is
yes just because of a large he does not automatically mean that you're going to
be proud to be more violent either but what happens is
'cause military code well aslam are bound to that's all we're saying that
what what this is saying is
that leads to generally more poverty because you really need a lower paying
job and then you into uh... a lot of people end up committing more violent
crimes out of this sat what they see as necessity for money for basic goods on
and then what lucas is on the earlier too if there's also shuts down at your
lekin also has been done to shut down an area of your brain
that relates a judgment making an emotion and still you are more likely to
be
ration commit some sort of crime and not relate to that of the human level like
you and yet i think that what we're not in your brain cells
really really interesting
i think it's good to go into a kind of like a critical mindset but
but very interesting i'll definitely listening to the podcast later
merits insecure maturity report details read our clan mother jones
and
in the interest of last night
yes so i'm glad that she said that so route we are showing the i_q_ level drop
because that's like a proxy for intelligencer fact of the brain but
doesn't like the lead being there doesn't just mean
your seven percent less
good at math
leggett it does damage the brain and it's not just net intelligent doesn't
mean you just can't remember when napoleon invaded such-and-such a city
it's doing damage difficulty bringing some of us have to do with your ability
to regulate emotions and things like that
and so uh... let's get a discussion going the comments when i think is
really interesting is that we're now discovering possibilities correlation
between leaden violence what other toxins are out there that could be a
great affecting us in a negative way
house crazy stuff in japan is our reform and maybe some toxin is making them a

knows now to brave new world of
