Q & A

  • What is the current state of gun violence rates in America compared to the mid-2010s?

    -Gun violence rates in America have increased in recent years after reaching historic lows in the mid-2010s, and they remain higher than in some other parts of the developed world.

  • What does the speaker suggest about the effectiveness of existing gun laws?

    -The speaker suggests that the notion that gun laws don't work is not supported by evidence, and that gun safety measures have been proven to save lives through repeated studies.

  • What is the issue with the majority of studies on the effect of gun control laws according to the speaker?

    -The issue is that of the thousands of studies conducted, nearly all are so flawed as to be total nonsense, and only about a hundred good studies are usually ignored or misrepresented by politicians and the media.

  • What does Statistician Aaron Brown suggest about the causal conclusions of most published journal articles on public policy issues?

    -Aaron Brown suggests that if you think most published journal articles on public policy issues have clear causal conclusions, such as a specific gun control regulation working or not, you would be mistaken.

  • What is the significance of the 2020 meta-analysis from the Rand Corporation mentioned in the script?

    -The 2020 meta-analysis from the Rand Corporation analyzed 27,900 studies on the effectiveness of gun control regulations and concluded that only 0.4%, or 123 studies, were rigorous enough to provide meaningful results.

  • What is the main argument against the quality of data in gun control research according to Brown?

    -Brown argues that the quality of data in gun control research is poor, making it nearly impossible for researchers to determine the effect of a law on gun violence, if any.

  • What are the three laws that the speaker suggests could significantly reduce firearm mortality if implemented?

    -The three laws suggested are universal background checks, ammunition checks, and identification of firearms through ballistic imprinting.

  • What is the problem with using synthetic comparisons in gun control research?

    -The problem with synthetic comparisons is that they may not accurately represent the actual effect of a law, as they can be influenced by external factors and do not account for individual state or regional differences.

  • What does the speaker claim about the effect of Connecticut's permit requirement for handgun purchases on its gun murder rate?

    -The speaker claims that the 40% reduction in gun murder rate attributed to Connecticut's permit requirement is flawed because it compared the state to a synthetic construct rather than to itself in prior years or to states without such changes.

  • What is the speaker's view on the impact of bans on assault weapons and large capacity magazines on mass shootings?

    -The speaker's view is that the impact of bans on assault weapons and large capacity magazines on mass shootings is inconclusive due to data problems that affect all gun control policy research.

  • What does the speaker suggest about the role of individual and cultural factors in gun violence?

    -The speaker suggests that individual and cultural factors play a significant role in gun violence and that these factors are more influential than any regulation, making it difficult to draw broad conclusions about the effectiveness of gun control measures.

  • What is the implication of the speaker's statement about the current state of scientific research on gun control?

    -The implication is that current scientific research on gun control is insufficient and potentially misleading, and that it should not be used as the sole basis for policy decisions.

📜 The Challenge of Effective Gun Legislation

This paragraph discusses the complexity and urgency of implementing common sense gun control laws in the United States. It acknowledges the increase in gun violence rates despite existing regulations and argues for additional, simple laws that could significantly impact this issue. The paragraph also refutes the notion that gun laws are ineffective, citing evidence and data that support their life-saving potential. However, it points out the flawed nature of thousands of studies, emphasizing the need for rigorous research to guide policy. Statistician Aaron Brown's expertise is highlighted, noting the difficulty in drawing causal conclusions from most published articles on public policy issues, including gun control. The paragraph underscores the importance of avoiding policies based on flawed research, which can lead to unintended consequences such as criminalizing law-abiding citizens and exacerbating racial and socioeconomic inequities in the justice system.

05:00

🔎 The Limitations of Gun Control Research

The second paragraph delves into the methodological issues and data limitations that plague gun control research. It explains how the rarity of gun violence makes it challenging to statistically measure the impact of gun control laws. The paragraph also criticizes the suppression of research results that do not support the intended narrative of gun control effectiveness. It highlights the importance of three specific laws—universal background checks, ammunition checks, and ballistic imprinting identification—as potentially impactful measures. However, it also points out the media's and politicians' tendency to focus on studies with sensational claims rather than rigorous evidence. The paragraph concludes by emphasizing the need for caution in drawing conclusions from social science research, particularly when it pertains to rare events like gun homicides.

10:00

🏛️ Cultural and Contextual Factors in Gun Control

This paragraph explores the cultural and contextual differences in gun control regulations across various states and their impact on crime rates. It suggests that states with strong gun control laws tend to be wealthier, more liberal, and urban, which may contribute to their lower crime rates independently of the gun laws. The paragraph also discusses the potential unintended consequences of enforcing strict gun laws in areas with different socio-economic conditions. It touches on the debate surrounding assault weapons and large capacity magazine bans, noting the difficulty in drawing conclusions due to varying definitions and data limitations. The paragraph emphasizes that while mass shootings are a concern, they represent a small fraction of gun violence and that the effect of bans on these incidents is inconclusive.

15:01

🚨 The Complexity of Gun Safety and Policymaking

The final paragraph addresses the complexity of gun safety and the challenges of policymaking in this area. It acknowledges the difficulty of providing a definitive answer to whether guns make individuals safer or more at risk, given the significant individual differences that can influence this outcome. The paragraph criticizes the use of sensational studies to inform legislation and calls for a more nuanced understanding of the factors that contribute to gun violence. It also discusses the broader implications of gun control policies, such as the potential for increased black market activity and the proliferation of 'ghost guns.' The paragraph concludes by emphasizing the need for rigorous scientific investigation and a balanced approach to policymaking that considers both the potential benefits and costs of gun control measures.

Keywords

💡Gun Legislation

Gun legislation refers to laws and regulations that govern the sale, possession, and use of firearms. In the video's context, it emphasizes the need for 'common sense' reforms to address gun violence. The script mentions that despite existing laws, there is a call for additional measures that could potentially reduce firearm-related incidents, illustrating the ongoing debate over the effectiveness and necessity of further gun control.

💡Gun Violence

Gun violence is the act of using firearms to inflict physical harm or death. The video discusses the fluctuating rates of gun violence in America, noting an increase in recent years. It serves as the central issue that the script aims to address through policy reforms and highlights the urgency of the situation as a public health crisis.

💡Common Sense Reforms

Common sense reforms are practical and widely accepted changes that are believed to improve a situation without drastic measures. The script uses this term to describe the proposed gun laws that are simple yet could significantly impact gun violence rates. It suggests that these reforms are based on social science research and are advocated as a non-controversial approach to gun control.

💡Firearms Offenses

Firearms offenses refer to crimes involving the illegal use or possession of guns. The video mentions the prosecution of a record number of firearms offenses, indicating efforts to enforce existing gun laws and the complexity of the issue when considering the balance between law enforcement and individual rights.

💡Flawed Research

Flawed research denotes studies that have methodological weaknesses or biases that undermine their conclusions. The script criticizes much of the research on gun control laws, suggesting that many studies are not rigorous enough to provide meaningful results, which complicates the formation of evidence-based policies.

💡Meta-Analysis

A meta-analysis is a statistical technique that combines the results of multiple studies to draw overall conclusions. The video cites a meta-analysis by the Rand Corporation, which evaluated thousands of studies on gun control and found very few that were methodologically sound, underscoring the difficulty in establishing causality in gun policy research.

💡Statistical Significance

Statistical significance is a measure that determines whether an observed effect is likely to be real or due to random chance. The script uses the concept to critique studies that claim significant findings, suggesting that many such results could be coincidental rather than indicative of a true relationship between gun laws and violence reduction.

💡Ghost Guns

Ghost guns are firearms that are assembled from parts and may not have serial numbers, making them untraceable. The video mentions the concern over the proliferation of these weapons, which can be easily assembled by anyone, including potential criminals or terrorists, highlighting the challenges in regulating homemade firearms.

💡Assault Weapons

Assault weapons are a category of firearms that are often subject to legislative debate due to their association with mass shootings. The script discusses the controversy surrounding bans on these weapons and the difficulty in measuring their impact on gun violence, given varying definitions and the rarity of mass shootings in the context of overall gun homicides.

💡Mass Shootings

Mass shootings are incidents in which multiple people are shot, typically in a public place. The video addresses the debate on whether bans on certain types of firearms have reduced the occurrence or severity of mass shootings, noting the challenges in defining such events and the inconclusive evidence regarding policy effectiveness.

💡Public Health Crisis

A public health crisis refers to a situation where a health issue becomes widespread and poses a significant threat to a community or population. The video concludes by framing gun violence as a public health crisis that requires a comprehensive approach and scientific research to inform policy and prevention strategies.

social science research shows that a

The notion that gun laws don't work,

play00:51

Of the thousands of studies that

play00:52

have been done on the effect of gun

play00:54

control laws, nearly

play00:56

all are so flawed as to be total

play00:58

nonsense.

play00:59

A hundred or so good studies

play01:01

are usually ignored or

play01:03

misrepresented by politicians, and

play01:04

the media

play01:06

Statistician Aaron Brown has taught

play01:07

at NYU and the University of

play01:09

California at San Diego.

play01:11

He's a columnist for Bloomberg and a

play01:13

leading expert on risk management.

play01:15

If you think most published journal

play01:16

articles on public policy issues

play01:18

have clear causal conclusions, such

play01:20

as at a specific gun control

play01:22

regulation does or does not work,

play01:24

you would be mistaken.

play01:26

Federal gun crime prosecutions are

play01:27

up 16 percent since I took

play01:29

office, but we must do more,.

play01:31

And I think there needs to be

play01:32

vigorous prosecution of gun laws on

play01:34

the books.

play01:34

Last year, we prosecuted

play01:37

a record number of firearms

play01:39

offenses.

play01:40

Gun control policies based on flawed

play01:42

research can have tremendous costs,

play01:44

may turn otherwise law abiding

play01:46

citizens into criminals, and

play01:48

they increase prosecutorial power

play01:50

and mass incarceration.

play01:52

They exacerbate the racial and

play01:54

socioeconomic inequities in the

play01:56

criminal justice system.

play01:57

Brown points to a 2020 meta analysis

play01:59

from the nonpartisan research

play02:01

organization the Rand Corporation

play02:03

that analyzed twenty seven thousand

play02:04

nine hundred studies on the

play02:06

effectiveness of gun control

play02:07

regulations.

play02:09

The authors concluded that point

play02:10

four percent, or only 123,

play02:13

were rigorous enough to provide

play02:15

meaningful results.

play02:16

And even among those, many didn't

play02:18

answer the most pressing question

play02:19

for policymakers whether

play02:21

gun control laws can reduce

play02:23

violence.

play02:24

One hundred twenty three studies

play02:25

that met the Rand criteria were the

play02:26

best of the bunch, but they still

play02:28

had serious defects.

play02:30

In fact, given the uncertainties in

play02:31

the data, it's next to impossible

play02:33

for any study to prove that a

play02:35

particular gun control measure had

play02:37

any effect whatsoever.

play02:38

The only thing we can say

play02:39

confidently is many of the most

play02:41

widely trumpeted results are

play02:43

likely based on random chance alone.

play02:45

Peer reviewed journals generally

play02:47

accept a result a statistically

play02:49

significant if as a one in 20

play02:51

chance or less of being due to

play02:52

random chance.

play02:54

This means that if researchers run

play02:55

100 studies on the relationship

play02:57

between two things that obviously

play02:59

have no connection to each other at

play03:00

all. Say milk consumption

play03:02

and car crashes.

play03:04

By pure chance, they can be expected

play03:06

to get five statistically

play03:07

significant results that are

play03:09

entirely coincidental, such

play03:11

as that milk drinkers get into more

play03:13

accidents.

play03:14

So what was wrong with one hundred

play03:15

and twenty three studies that met

play03:17

the approval of the RAND

play03:18

researchers?

play03:19

These papers tested 722

play03:21

separate hypotheses about the impact

play03:23

of gun control laws at the five

play03:25

percent level of significance,

play03:27

even if there were no relationship

play03:29

between gun laws and violence, much

play03:31

like the relationship between

play03:32

drinking milk and getting into car

play03:33

accidents.

play03:35

We'd expect about five percent of

play03:36

those 722 tests,

play03:38

or 36 results to

play03:40

show that gun regulations had a

play03:41

significant impact.

play03:42

Collectively, these papers found

play03:44

significant results for only 18

play03:46

combinations of gun control, measure

play03:48

and outcome.

play03:49

Half would we would expect by random

play03:51

chance if gun control measures had

play03:52

no effect at all.

play03:53

But let's assume that these 18

play03:55

statistically significant results

play03:57

were not the result of random chance

play03:59

and do demonstrate a relationship

play04:00

between gun laws and violence.

play04:02

Are there any meaningful takeaways?

play04:05

Brown argues that these findings

play04:06

actually have very little relevance

play04:08

for policymakers because of the poor

play04:09

quality of the data.

play04:11

Researchers often conceal this by

play04:13

using the shoddy data to build

play04:14

conceptual models and then claiming

play04:16

high confidence in the results of

play04:18

the models spit out.

play04:19

In reality, gun violence is rare

play04:21

enough that it's nearly impossible

play04:22

for researchers to figure out what

play04:24

difference a law makes, if any.

play04:26

For example, one of the significant

play04:28

results cited by Rand found that

play04:30

more restrictive child access laws

play04:32

could stop a total of two kids

play04:34

across 11 states from

play04:35

injuring themselves each year with a

play04:37

gun, either by accident or by

play04:39

attempting suicide.

play04:41

These events are simply too rare to

play04:43

get meaningful statistical

play04:44

estimates.

play04:45

There's simply too much variation

play04:47

from other factors and random noise

play04:48

to give any precise estimate of this

play04:50

number.

play04:51

Brown says similar data issues

play04:52

plague most social science research

play04:54

that tries to tease out the effects

play04:56

of a policy change on rare events

play04:58

like accidents, suicides or

play05:00

homicides,

play05:01

These studies are doomed from the

play05:02

start. Regulations could take years

play05:04

to implement and enforce

play05:06

and will likely affect only a small

play05:07

fraction of new gun sales.

play05:09

New gun sales are a small fraction

play05:11

of all total firearms owned.

play05:13

Therefore, the most optimistic

play05:15

projection of first year effect of a

play05:17

gun control rule would be a small

play05:19

fraction of one percent of gun

play05:21

homicides.

play05:23

But gun homicide rates in states

play05:24

change by an average of six percent

play05:26

in years, with no legislative

play05:28

changes.

play05:29

Fatal data problems like this

play05:30

frustrate all gun control research

play05:32

that attempts to tease out the

play05:33

effect of marginal policy changes

play05:36

on suicides, homicides or

play05:37

anything else.

play05:39

It frustrates opponents of gun

play05:41

control who sometimes argue that

play05:42

guns are more often used for

play05:44

self-defense than to victimize

play05:46

others. Anyone basing a gun

play05:48

control position on scientific

play05:49

evidence is building on sand.

play05:52

We have no useful empirical data on

play05:54

the subject, and we have no body of

play05:55

work that rises above the level of

play05:57

expected false positives, either for

play05:59

or against gun control,

play06:01

According to Brown. There's another

play06:03

major takeaway from the RAND

play06:04

analysis.

play06:05

The numbers indicate that

play06:06

researchers are suppressing results

play06:08

that show gun control policies do

play06:09

nothing or have the opposite of

play06:11

their intended effect.

play06:12

Of the seven hundred and twenty two

play06:14

hypotheses contained in the 123

play06:16

studies that met the approval of the

play06:18

RAND researchers, only one

play06:20

significant result found that a gun

play06:22

control measure had made gun

play06:23

violence worse, even

play06:25

by random chance.

play06:26

Those studies should have yielded

play06:28

about 36 false positive results,

play06:30

and roughly half of them should have

play06:32

shown the opposite of what

play06:33

researchers expected.

play06:35

So why is it that only one published

play06:36

finding showed that a gun control

play06:38

measure didn't work,

play06:40

Given the vast number of studies

play06:41

done, the vast number of hypotheses

play06:43

tested, we would expect more

play06:45

of these negative results by random

play06:47

chance alone.

play06:48

The fact that only one was found

play06:50

suggests strongly researchers are

play06:51

suppressing negative results.

play06:53

The rarity of pro-gun control

play06:55

results in the near total

play06:57

absence of anti-gun control results

play06:59

are strong evidence that we know

play07:01

nothing about the effect of gun

play07:02

control regulations.

play07:04

Three laws are particularly

play07:05

important. Universal background

play07:07

checks. Ammunition checks.

play07:08

Identification of firearms through

play07:10

ballistic imprinting.

play07:11

Each of these laws by themselves

play07:13

could reduce firearm mortality by

play07:14

about 60 to 80 percent.

play07:16

If all three were implemented

play07:18

nationally in the same way as

play07:19

they're implemented in some states,

play07:21

we could reduce firearm mortality by

play07:22

about 90 percent.

play07:23

Gun control researchers aren't the

play07:25

only ones guilty of misusing

play07:27

statistics.

play07:28

The studies that get the most

play07:29

attention from reporters and

play07:30

politicians are the ones that claim

play07:32

the most shocking and powerful

play07:33

effects, which, according to Brown,

play07:36

are usually also based on the

play07:37

flimsiest evidence.

play07:39

None of the 123 studies blessed

play07:40

by Rand got significant media or

play07:42

legislative attention.

play07:44

It was the worst studies with the

play07:46

most outrageous claims from

play07:48

among the 27,000

play07:50

that Rand excluded

play07:51

that made the headlines.

play07:53

It's common sense you should need a

play07:55

license to buy and own a firearm.

play07:56

And states like Connecticut that did that, they saw 40 percent drops in gun violence and 15 percent drops in suicides.

play08:04

Hundreds of studies have been done

play08:06

comparing gun homicide rates

play08:08

before and after states changed

play08:09

their gun control laws.

play08:11

One prominent study made the

play08:13

astounding claim that

play08:15

a permit requirement for handgun

play08:17

purchases in Connecticut reduced

play08:19

their gun murder rate by 40 percent.

play08:21

It is true that Connecticut's gun

play08:22

murder rate fell rapidly after that

play08:24

law was passed in 1995,

play08:27

but so did gun murder rate

play08:28

throughout the country in order

play08:30

to form a conclusion about the

play08:32

effect of the Connecticut law.

play08:34

You would want to compare

play08:35

Connecticut to something as similar

play08:36

as possible that did not make

play08:38

the change.

play08:39

But the authors do not compare

play08:41

Connecticut to itself in prior

play08:42

years, nor to all other states.

play08:45

Their 40 percent claim as the actual

play08:47

murder rate in Connecticut compared

play08:49

to something they call a synthetic

play08:51

Connecticut that they constructed

play08:52

for the purpose of their study.

play08:54

The combination of mostly Rhode

play08:55

Island, but also Maryland,

play08:57

California, Nevada and New

play08:58

Hampshire.

play08:59

The paper claims to show a 40

play09:01

percent decline in gun murders in

play09:03

Connecticut as compared to synthetic

play09:04

Connecticut. But Brown says this

play09:06

entire effect is due to the fact

play09:08

that Rhode Island experienced of

play09:09

about 20 extra murders between 1999

play09:11

and 2003 and synthetic

play09:13

Connecticut was more than 72

play09:15

percent Rhode Island.

play09:17

Even comparing to synthetic

play09:18

Connecticut, the decline, the

play09:19

authors found, didn't last.

play09:21

Although the law remained on the

play09:22

books by 2006,

play09:25

the gun murder rate in Connecticut

play09:26

had surpassed synthetic Connecticut

play09:28

and continued to increase to the

play09:30

point where it was 46 percent

play09:31

higher.

play09:32

The authors, despite publishing in

play09:34

2015, elected

play09:36

to ignore data from 2006

play09:38

and afterwards they're making

play09:40

strong claims based on complex

play09:42

models and uncertain data.

play09:44

Were they cherry pick their time,

play09:46

periods and locations to get their

play09:48

preferred outcome.

play09:50

This is unfortunately common in

play09:51

social science research on gun

play09:53

control.

play09:54

We know that states with the most

play09:55

gun laws tend to have

play09:57

the fewest gun deaths.

play09:58

What people in Vermont, and I

play10:00

suspect New Hampshire understand

play10:02

is that guns in our part of

play10:04

the world are very different than

play10:05

guns in Chicago, Los Angeles,

play10:08

in New York.

play10:08

The real story on gun control is

play10:10

that states with strong gun control

play10:12

regulations are different from

play10:14

states with weaker gun control

play10:15

regulations.

play10:16

They're richer, more liberal, more

play10:18

urban, and they have lower murder

play10:20

and suicide rates.

play10:22

The effect is almost certainly the

play10:23

reverse. Places with low crime

play10:25

rates are more willing to give up

play10:27

personal guns, and richer people

play10:29

put more trust in the police to

play10:30

protect them from crime.

play10:33

But the cultural differences are

play10:34

too big, and there's just too much

play10:36

uncertainty about this to say

play10:38

anything about what would happen if

play10:40

we enforce Greenwich Connecticut

play10:41

laws in Festus, Missouri.

play10:43

We can ban assault weapons and

play10:45

high capacity magazines

play10:46

in this country.

play10:48

Once again,

play10:50

I got that done when I was a

play10:51

senator, and it brought down these

play10:53

mass killings.

play10:54

Then there's the question of whether

play10:55

bans on assault, style weapons and

play10:57

large capacity magazines, which

play10:59

are often passed together, have

play11:01

reduced the frequency or deadliness

play11:02

of mass shootings.

play11:04

Researchers define basic terms like

play11:06

assault weapons and mass shootings

play11:08

differently.

play11:09

They limit their data, buy, time,

play11:10

place or other factors, such

play11:12

as classifying an event as an act of

play11:14

terror, and therefore we're not

play11:15

considering it a mass shooting.

play11:17

There's no reason someone needs a

play11:19

weapon, a war with one hundred

play11:21

rounds, 100 bullets.

play11:23

These varying definitions make

play11:25

studies apples to oranges

play11:26

comparison, and they

play11:28

invite researchers to cherry pick

play11:30

finding limited data sets based

play11:32

on number of casualties, type of

play11:34

weapons, time period and other

play11:35

factors to support whatever

play11:37

conclusions the researcher wants.

play11:39

The bottom line is the effect of

play11:41

bans on large capacity magazines

play11:43

or assault. Weapons on mass

play11:45

shootings is inconclusive for the

play11:46

same data problems that affect all

play11:48

gun control policy research.

play11:51

But there's a further problem.

play11:53

Mass shootings are extremely rare

play11:55

relative to other forms of gun

play11:57

violence, and most of them don't

play11:59

involve assault weapons.

play12:01

Depending on what definitions you

play12:02

use, mass shootings involving

play12:04

assault weapons are a small fraction

play12:06

of one percent of all gun homicides.

play12:09

But that 10 years we had it done.

play12:12

The number of mass shootings

play12:13

actually went down, and since

play12:15

then the number of

play12:17

massacres has increased one hundred

play12:19

eighty three percent.

play12:20

Mass shootings went up 200

play12:22

percent in the decade after the

play12:24

assault weapons ban expired.

play12:26

For example, the U.S.

play12:27

federal ban on assault weapons and

play12:29

large capacity magazines was in

play12:31

place for 10 years from 1994

play12:33

to 2004,

play12:35

before, during and after which many

play12:37

societal factors cause crime rates

play12:39

to vary widely, making

play12:41

it impossible to draw useful

play12:42

conclusions about the effect of

play12:44

the ban on anything and

play12:46

in particular on something as rare

play12:47

as mass shootings.

play12:49

This type of mass violence does not

play12:51

happen in other advanced countries.

play12:53

States and countries with bans

play12:54

define assault weapons and other key

play12:56

elements of laws differently.

play12:58

So combined with the data problems

play13:00

inherent in comparing different

play13:01

populations of people over different

play13:03

periods of time.

play13:04

Comparisons between states and

play13:06

countries are almost meaningless.

play13:08

Another Rand Corporation meta

play13:10

analysis updated in 2020

play13:11

found inconclusive evidence that

play13:13

these bands have any effect on mass

play13:15

shootings or violent crime.

play13:16

But how about the more

play13:17

straightforward question of whether

play13:19

owning a gun makes you more or less

play13:21

safe? One widely influential

play13:23

study that has constantly resurfaced

play13:25

in headlines since it was published

play13:26

in the New England Journal of

play13:27

Medicine in 1993, concluded

play13:29

that quote "Rather than confer

play13:31

protection, guns kept in the home

play13:33

are associated with an increase in

play13:35

the risk of homicide by a family

play13:36

member or intimate acquaintance."

play13:38

Brown says there are major problems

play13:40

with this study.

play13:41

First of all, the researchers

play13:42

concluded that keeping a gun at home

play13:44

increases a person's risk of being

play13:46

killed. But nearly half the murders

play13:48

they included in their analysis were

play13:50

not committed with firearm and

play13:51

among gun owners who were killed

play13:53

with a gun.

play13:54

The authors didn't establish whether

play13:55

the weapon used was the victim's own

play13:57

gun or if it belonged to another

play13:59

person.

play14:00

But Brown says the main reason

play14:01

research on this topic is

play14:03

inconclusive is because the answer

play14:05

almost entirely depends on

play14:06

individual differences.

play14:08

They can easily be controlled for in

play14:09

social science research.

play14:11

A gun expert with a gun safe and

play14:13

a high crime neighborhood may well

play14:14

be safer with the gun, whereas

play14:16

a careless alcoholic living in a low

play14:18

crime area who keeps loaded guns

play14:20

in his kids closet is certainly

play14:22

going to be less safe.

play14:24

People want a simple overall answer

play14:25

to whether guns make you less safe

play14:27

or more safe in order to

play14:29

inform legislation, but social

play14:31

science cannot deliver that.

play14:33

When the researchers behind the 1993

play14:35

study tried to control for all the

play14:36

variation between people to tease

play14:38

out just the effect of owning a gun.

play14:40

Their analysis found that other

play14:41

factors can increase your risk of

play14:43

being killed even more than having a

play14:45

firearm at home.

play14:46

What most pressing politicians,

play14:47

citing the blockbuster 1993

play14:49

study leave out is that although it

play14:51

did find that owning a gun increased

play14:53

your risk, there were other things

play14:55

that were much more dangerous,

play14:56

including living alone or being a

play14:58

renter.

play14:59

There were no coherent arguments

play15:01

as to why we wouldn't do this.

play15:02

I am open and ready to listen

play15:04

and discuss all ideas that

play15:06

will actually work.

play15:08

Advocates who feel strongly

play15:10

and are pushing every day

play15:12

to make the rational changes.

play15:14

Activists may argue that even if the

play15:16

evidence isn't solid, any new

play15:18

restriction on guns is worth trying

play15:20

in the effort to reduce violence,

play15:22

since there's also no convincing

play15:23

evidence that gun control doesn't

play15:25

work.

play15:26

After all, most laws don't have firm

play15:27

scientific underpinnings, and

play15:29

it's certainly plausible that

play15:31

general government discouragement of

play15:32

guns can reduce violence over long

play15:34

periods of time.

play15:35

We maybe can't save

play15:38

everybody, but we could save some.

play15:40

But these policies also have

play15:41

significant costs restricting

play15:43

our freedoms and causing more people

play15:45

to go to prison disproportionately

play15:47

from poor and minority communities.

play15:49

Further legal restrictions also grow

play15:51

black markets and illegal weapons

play15:53

and incentivize the use of homemade

play15:55

ghost guns, which are harder to

play15:56

trace and regulate.

play15:58

Want to rein in the proliferation of

play15:59

so-called ghost guns,

play16:02

anyone from a criminal

play16:04

to a terrorist can

play16:06

buy this kit as little

play16:07

as 30 minutes put together a

play16:09

weapon.

play16:10

And it's not just gun control.

play16:13

Nearly all similar policy analysis

play16:15

suffers from the same issue.

play16:16

Too much complexity for the

play16:18

available data partisans

play16:20

yearn for scientific backing for

play16:21

their views, but scientists cannot

play16:23

deliver it.

play16:24

Researchers flocked to the field

play16:26

because there's money and interest

play16:27

in results, and they peer review

play16:29

each other's work without applying

play16:31

the kind of rigor that would

play16:32

eliminate nearly all publications

play16:35

We can and will stop this evil

play16:37

contagion.

play16:38

Not just the gun crisis,

play16:40

but what is actually a public health

play16:42

crisis.

play16:43

This is an epidemic for God's sake.

play16:45

In the 1990s, the NRA

play16:47

convinced Congress to cut all

play16:49

of CDCs funding for gun research.

play16:51

But now, in a stunning turn,

play16:53

the current director of the CDC

play16:54

is announcing a plan to reduce gun

play16:56

violence.

play16:57

The director of the CDC, Rochelle

play16:59

Walensky, declared in August that

play17:01

the agency would begin treating gun

play17:02

violence as a public health crisis,

play17:04

and Congress approved an initial $25

play17:07

million in new funds toward

play17:08

scientific research on the topic.

play17:10

For those who are worried about

play17:12

research in this area, I'm

play17:14

not here about gun control.

play17:16

I'm here about preventing gun

play17:17

violence and gun deaths.

play17:18

These are complex issues that

play17:19

require rigorous scientific

play17:21

investigation to come to any kind

play17:23

of useful conclusion, and

play17:25

they depend far more on individual

play17:26

variation, as well as broad social

play17:29

and cultural factors than

play17:30

on any regulation.

play17:32

We should not panic and pass more

play17:34

laws that sweep up innocent victims

play17:36

while doing more harm than good.

play17:38

All with the alleged backing of

play17:39

science, they can't possibly

play17:41

tell us what we need to know.
