Excerpt:

The takeaway from the story of Dickey, Rosenberg, and the 1993 gun study at the center of the piece is that the congressman was correct to begin with. The CDC shouldn’t be studying gun violence.

Titled “Gun Ownership as a Risk Factor for Homicide in the Home” and published in The New England Journal of Medicine, the 1993 study looked at 388 people who had been killed in their homes and matched them to 388 neighbors of similar age, sex, and race. One hundred and seventy-four of the victims lived in houses where at least one gun was present versus only 139 of the matched controls.

With scary music and breathless claims, the video tells viewers that if you had a gun in your house, you were 200 percent more likely to be killed with a gun in your home and 400 percent more likely to kill yourself. 

These are both exaggerations and misstatements of the study results. It didn’t address suicide risk at all, nor gun homicides. It found households in which a resident had been murdered at home by any means had a 25 percent greater frequency of having a gun, not 200 percent. But this doesn’t mean owning a gun increases your risk of being killed by 25 percent. 

This is a classic statistical error known as the “base rate fallacy” and is particularly important when studying rare events, like people murdered in their homes. Suppose 10 people are murdered in their homes, and five of those homes had guns. A matched set of 10 people who were not murdered in their homes found only four homes had guns. So there are 25 percent more guns in the homes of murder victims than matched nonmurder victims (Five vs. four).

But what if you put those 20 people in the context of another million, none of whom were murdered in their homes, half of whom had guns in their homes and half of whom didn’t. The rate for gun owners to be murdered at home becomes five out of 500,009, while the rate for non-gun owners becomes five out of 500,011. So now we find that the risk is 0.0004 percent higher.

In other words, being murdered in your home means you have a 25 percent higher chance of having a gun, but having a gun means you have only a 0.0004 percent greater chance of being murdered in your home. Those are not the same thing.

The finding that owning a gun made study subjects less safe was also a conclusion selected from much stronger statistical results that didn’t fit the authors’ political views and, thus, weren’t mentioned in the study. Yes, 25 percent more victims’ homes had guns than control homes, but 38 percent more victims had controlled security access to their property. Why not lobby against gates as a public health matter? Twenty times as many victims had gotten in trouble at work because of drinking, so why worry about guns when drinking at work is two orders of magnitude more dangerous? Renting and living alone were far more dangerous than having a gun. Victims were less likely than controls to own a rifle or a shotgun, so why not a government program to trade in handguns for long guns?

A Framework for Defining a Role for Insurers in “Uninsurable” Risks: Insights from COVID-19

Excerpt:

RETHINKING UNINSURABILITY While many have viewed insurability as a binary choice with respect to a risk (i.e., insurable or uninsurable), insurability is more appropriately considered on a continuum, ranging from easy-to-insure, such as automobile or life insurance, to difficult-to-insure, such as pandemic, loss of the electrical grid, and other extreme catastrophic risks.

FRAMEWORK The role of private and public sectors in dealing with risks that are difficult-to-insure should be to develop strategies that enable a greater degree of insurability. To do so, the framework suggests that policymakers consider three fundamental options in dealing with the insurance industry:

Status Quo (SQ) –This option (SQ) contemplates a similar dynamic to that experienced with COVID-19, wherein businesses, nonprofits, and local governments found limited (if any) insurance coverage for their losses and ex post relief programs funded by the government.

Service Provider (SP) – This option (SP) contemplates an administrative, non-risk-bearing role for the insurance industry while the entire cost of claims would be publicly financed.

Service and Risk (SR) –In addition to its role as a service provider as characterized by SP, this option (SR) would expect insurers to commit capital – in an amount that does not threaten their financial viability – to cover a specified layer or other defined element of losses.

Excerpt:

Today, as part of the U.S. Department of Transportation’s efforts to increase roadway safety and encourage innovation, the National Highway Traffic Safety Administration published the initial round of data it has collected through its Standing General Order issued last year and initial accompanying reports summarizing this data.

The SAE Level 2 advanced driver assistance systems summary report is available here, while the SAE Levels 3-5 automated driving systems summary report is available here. Going forward, NHTSA will release data updates monthly.

These data reflect a set of crashes that automakers and operators reported to NHTSA from the time the Standing General Order was issued last June. While not comprehensive, the data are important and provide NHTSA with immediate information about crashes that occur with vehicles that have various levels of automated systems deployed at least 30 seconds before the crash occurred.

“The data released today are part of our commitment to transparency, accountability and public safety,” said Dr. Steven Cliff, NHTSA’s Administrator. “New vehicle technologies have the potential to help prevent crashes, reduce crash severity and save lives, and the Department is interested in fostering technologies that are proven to do so; collecting this data is an important step in that effort. As we gather more data, NHTSA will be able to better identify any emerging risks or trends and learn more about how these technologies are performing in the real world.”

Abstract:

Much research has shown a general decrease in the negative health response to extreme heat events in recent decades. With a society that is growing older, and a climate that is warming, whether this trend can continue is an open question. Using eight additional years of mortality data, we extend our previous research to explore trends in heat-related mortality across the United States. For the period 1975–2018, we examined the mortality associated with extreme-heat-event days across the 107 largest metropolitan areas. Mortality response was assessed over a cumulative 10-day lag period following events that were defined using thresholds of the excess heat factor, using a distributed-lag nonlinear model. We analyzed total mortality and subsets of age and sex. Our results show that in the past decade there is heterogeneity in the trends of heat-related human mortality. The decrease in heat vulnerability continues among those 65 and older across most of the country, which may be associated with improved messaging and increased awareness. These decreases are offset in many locations by an increase in mortality among men 45–64 (+1.3 deaths per year), particularly across parts of the southern and southwestern United States. As heat-warning messaging broadly identifies the elderly as the most vulnerable group, the results here suggest that differences in risk perception may play a role. Further, an increase in the number of heat events over the past decade across the United States may have contributed to the end of a decades-long downward trend in the estimated number of heat-related fatalities.

Murder-Suicides By Pilots Are Vexing Airlines As Deaths Mount

Excerpt:

For decades, commercial airline travel has gotten progressively safer. But one cause of deaths has stubbornly persisted: pilots who intentionally crash in murder-suicides.


Preliminary evidence suggests the crash of a China Eastern Airlines Corp. jet in March may be the latest such tragedy, a person familiar with the investigation said. If confirmed, that would make it the fourth since 2013, bringing deaths in those crashes to 554.

So as aircraft become more reliable and pilots grow less susceptible to errors, fatalities caused by murder-suicides are becoming an increasingly large share of the total. While intentional acts traditionally aren’t included in air-crash statistics, they would be the second-largest category of deaths worldwide if they were, according to data compiled by Bloomberg. By comparison, 1,745 people died as a result of pilot error, mechanical failures or other causes on Western-built jets from 2012 through 2021.

A Resilient Future

Excerpt:

If we consider how risk events unfold in reality, they usually occur through a sequence of interacting factors (see Figure 1). For example: A control does not quite work as intended because the usual supervisor is not available, and coincidentally a staff member has unintended access to a system from which they are able to extract personal information. On any other day, those conditions might have been different and resulted in another outcome. The reality, therefore, is that risks emerge as a result of a complex series of interactions among a large number of factors, and small changes in conditions can lead to significantly different risk outcomes.

Risk events also often involve active participants who learn and adapt their behaviors accordingly. Cyber is a good example—the attacker generally is trying to outthink their adversary and stay one step ahead. All of this means that past performance is not necessarily a reliable predictor of the future. There are too many things that can be subtly different, leading to hugely different outcomes.

Biological and Psychobehavioral Correlates of Credit Scores and Automobile Insurance Losses: Toward an Explication of Why Credit Scoring Works

Mary Pat Campbell

Link: https://www.jstor.org/stable/4138424

Graphic:

Abstract:

The most important new development in the past two decades in the personal lines of insurance may well be the use of an individual’s credit history as a classification and rating variable to predict losses. However, in spite of its obvious success as an underwriting tool, and the clear actuarial substantiation of a strong association between credit score and insured losses over multiple methods and multiple studies, the use of credit scoring is under attack because there is not an understanding of why there is an association. Through a detailed literature review concerning the biological, psychological, and behavioral attributes of risky automobile drivers and insured losses, and a similar review of the biological, psychological, and behavioral attributes of financial risk takers, we delineate that basic chemical and psychobehavioral characteristics (e.g., a sensation-seeking personality type) are common to individuals exhibiting both higher insured automobile loss costs and poorer credit scores, and thus provide a connection which can be used to understand why credit scoring works. Credit scoring can give information distinct from standard actuarial variables concerning an individual’s biopsychological makeup, which then yields useful underwriting information about how they will react in creating risk of insured automobile losses.

Are Seat Belts Making You Less Safe?

Mary Pat Campbell

Link: https://fee.org/articles/are-seat-belts-making-you-less-safe/

Excerpt:

In the 1960s, the federal government—in its infinite wisdom—thought that cars were too unsafe for the general public. In response, it passed automobile safety legislation, requiring that seat belts, padded dashboards, and other safety measures be put in every automobile.

Although well-intended, auto accidents actually increased after the legislation was passed and enforced. Why? As Lansburg explains, “the threat of being killed in an accident is a powerful incentive to drive carefully.”

In other words, the high price (certain death from an accident) of an activity (reckless driving) reduced the likelihood of that activity. The safety features reduced the price of reckless driving by making cars safer. For example, seatbelts reduced the likelihood of a driver being hurt if he drove recklessly and got into an accident. Because of this, drivers were more likely to drive recklessly.

The benefit of the policy was that it reduced the number of deaths per accident. The cost of the policy was that it increased the number of accidents, thus canceling the benefit. Or at least, that is the conclusion of University of Chicago’s Sam Peltzman, who found the two effects canceled each other.

His work has led to a theory called “The Peltzman Effect,” also known as risk compensation. Risk compensation says that safety requirements incentivize people to increase risky behavior in response to the lower price of that behavior.

Seat Belt Usage and Risk Taking in Driving Behavior

Abstract:

This study tested the hypothesis that seat belt usage is related to driver risk taking in car-following behavior. Individual vehicles on a Detroit area freeway were monitored to identify seat belt users and nonusers. Headways between successive vehicles in the traffic stream were also measured to provide a behavioral indicator of driver risk taking. Results showed that nonusers of seat belts tended to follow other vehicles closer than did users. Users were also less likely than nonusers to follow other vehicles at very short headways (one second or less). The implications of these findings for occupant safety in rear end collisions are discussed.

Why driving needs to feel less safe

Excerpt:

Motor vehicle fatalities in Connecticut have risen dramatically since the pandemic, echoing a trend that we’ve seen across the country. About 300 people are killed annually on Connecticut’s streets by motor vehicles, and about 100 times as many people (roughly 30,000) suffer injuries severe ePnough to warrant hospital admission.

Nationally, these figures are roughly 40,000 deaths and 3.4 million injuries per year. The U.S. is an outlier among developed countries in the number  of deaths that we tolerate on our roads, with a death rate 2 to 3 times that of similarly wealthy countries. The human cost of this carnage leaves no one untouched: almost everyone knows at least one person killed by a vehicle, not to mention millions of others who suffer from life-altering consequences like paralysis and traumatic brain injuries.

If we truly care about saving lives and preventing injuries, we need to change the mindset by which we view the act of driving.

Looking Beyond Sex

Excerpt:

With nonbinary genders recognized on legal documents, customers are beginning to ask for forms and applications to include nonbinary options as well—so they’re not forced into a false selection. Even so, a person still could make an inaccurate selection. A customer falsely selecting a nonbinary gender is slightly less risky for the insurance company than selecting a false binary gender, as nonbinary rates are likely to fall somewhere between male and female to ensure they’re not discriminatory.

In the end, providing false information on an insurance application is fraudulent activity regardless of the question. Many of the states that include nonbinary gender markers on birth certificates and/or driver’s licenses already require the individual to sign an affidavit stating that they are not changing their gender marker for a fraudulent purpose. The benefits of including options for nonbinary customers and the potential for more accurate risk evaluations hopefully will outweigh a possible increase in fraudulent activity.
