Anti selection in life insurance can be a complex issue, but it's essential to understand its impact on policyholders.
Anti selection occurs when insurers use certain practices to discourage or prevent high-risk individuals from applying for life insurance. This can lead to unfair treatment of those who need coverage the most.
As a result, high-risk individuals may be left without adequate protection, leaving their loved ones vulnerable in the event of their passing.
In some cases, anti selection can also drive up premiums for those who are already at a higher risk, making it even more difficult for them to afford coverage.

Understanding Anti-Selection
Anti-selection, also known as adverse selection, is a phenomenon where people act on known information to gain an advantage in securing or denying insurance policies.
Insurance providers use genetic data to make decisions about insuring individuals, and if they know someone has a genetic predisposition to a certain disease, they might exclude coverage for that disease, raise premiums, or refuse to insure the person.

DNA tests are more reliable than family medical history in identifying genetic markers that can predict disease development, giving people a more accurate idea of their risk.
A person with a high risk of developing a disease like Alzheimer's will likely seek ironclad coverage with high benefit levels to protect themselves.

Selection Meaning and Roots
Anti-selection, also known as adverse selection, refers to acting on known information to gain an advantage in securing or denying an insurance policy. This can happen when an insurer uses information about a person's genetic data to make decisions about insuring them.
Insurers may exclude coverage for certain diseases or raise premiums substantially if they know a person has a genetic predisposition to a specific condition. For example, if someone has a genetic predisposition to colon cancer, an insurer might exclude colon cancer coverage or raise premiums.
Genetic tests like 23andme and Ancestry.com can give people an idea of which diseases they're likely to develop over their lives. This can be more reliable than family medical history, which was previously used to determine disease risk.

People who get their test results and see a significant chance of developing a disease will often make sure they have ironclad coverage for that disease specifically, including high benefit levels. This can create an unfair advantage for individuals with access to this information.
The insurance industry is struggling to keep up with this issue, with annual losses in the hundreds of billions of dollars across all sectors. The life insurance industry is particularly hard hit, experiencing an estimated $75 billion loss annually.
Anti-Selection
Anti-selection is a significant issue for the insurance industry, causing annual losses in the hundreds of billions of dollars. It's estimated that the life insurance industry loses around $75 billion annually due to anti-selection.
Fraud, misrepresentation, and anti-selection pose a substantial financial burden to the insurance industry. This burden is so great that insurance companies charge higher premiums to mitigate the impact.
Anti-selection can occur when individuals use known information to gain an advantage on securing an insurance policy. For example, if someone knows they have a genetic predisposition to colon cancer, an insurer may exclude colon cancer coverage from a policy or raise premiums substantially.

Insurance providers use demographic information, such as age, gender, and ethnicity, to make assumptions about a person's health risks. However, with the availability of genetic data, individuals can now make more informed decisions about their insurance coverage.
The practice of anti-selection can lead to a situation where insurers are no longer profitable, and may even face serious repercussions, including being forced out of business. This would ultimately hurt policyholders in the long run, as they may be left without insurance coverage and face higher premiums for new policies.
Anti-selection can also hinder insurance innovation, increase the price consumers pay, and reduce insurer profits. It's a complex issue that requires a better understanding of the impact of anti-selective policyholder behavior on the life insurance industry.
Background
Insurance fraud is a complex issue with a long history. In 2016, a poll at the RGA Fraud Conference found that one-third of attendees believed fraud limited the number or face amount of simplified issue policies their companies were willing to write.

Fraud has been a problem in the insurance industry for a while now. Novel means and techniques to commit insurance fraud continue to emerge.
A survey conducted by RGA in 2016 showed that insurers needed digital tools to help identify or flag problems related to fraud. Insurers were looking for ways to combat the issue.
Fraud can have a significant impact on the insurance industry. Anti-selective behaviors, such as material misrepresentations, can be particularly harmful to both insurers and consumers.
Research Approach
In our research, we employed a mixed-methods approach to explore the concept of anti-selection. We conducted a comprehensive review of existing literature to identify key themes and patterns related to anti-selection.
Our literature review revealed that anti-selection is often associated with adverse selection, where individuals with high-risk profiles are more likely to purchase insurance. This is because they are more likely to file claims, which can increase costs for insurers.
We also analyzed data from various industries to examine the prevalence and impact of anti-selection. For instance, a study in the health insurance industry found that anti-selection was a significant problem, leading to higher premiums for consumers.

The data analysis highlighted the importance of understanding the root causes of anti-selection, which can include factors such as information asymmetry and moral hazard. By addressing these underlying issues, insurers can develop more effective strategies to mitigate anti-selection.
Our research also involved conducting interviews with industry experts to gain a deeper understanding of the practical challenges and opportunities related to anti-selection.
Impact and Concerns
The use of accelerated underwriting in life insurance has changed the way companies approach anti-selective behavior. Insurers are now more likely to promote higher levels of misrepresentation among applicants.
Faster decisions and ease of applications can lead to applicants being less invested in the process. This makes it easier for them to switch between companies for coverage.
Applicants may view the process as more "switchable" if they don't have to undergo exams or bloodwork, allowing them to easily apply to multiple companies.

Level of Concern
The level of concern among insurers regarding churning and stacking varies depending on the type of policies they write. For insurers focused on policies with small to mid-level face amounts, churning and stacking are of greater concern.

Insurers writing policies for high net worth individuals seem to be less concerned about these issues. This disparity may be due to the fact that high net worth individuals often have more complex insurance needs.
As the insurance industry evolves, insurers are concerned that the retirement of long-established agents may lead to increased churning in the future. This is because younger agents may be less familiar with established norms for ethical business practices.
Insurer concern with anti-selection has increased over the last 10 years, and it's becoming increasingly difficult to identify. Insurers acknowledge that anti-selection will likely continue to grow alongside automation.

Impact of Accelerated Underwriting
Accelerated underwriting has changed the way companies approach life insurance, making it easier and faster for applicants to get coverage. This increased ease of application can lead to anti-selective behavior among insurers.
Applicants may be less invested in the process if they don't have to undergo exams or bloodwork, viewing it as more "switchable." This can cause them to easily apply to multiple companies for coverage.
Faster decisions and ease of applications can promote higher levels of misrepresentation among applicants. Insurers expect greater opportunity for anti-selective behavior as companies become more comfortable with fluidless underwriting.
Distribution and Churning

Insurers selling primarily through a captive sales force are generally less concerned with churning and stacking.
Greater concern exists among insurers offering brokered sales and direct-to-consumer (D2C) products, especially if the underwriting is fluidless.
This makes it easier for applicants to "sprinkle across the industry to see what they can get through", as one interviewee noted.
D2C online questions may not be perceived as "real" to consumers, and they may not understand the implications of anti-selection on the industry and premium rates.
Distribution Model
Insurers with a captive sales force are often less concerned with churning and stacking.
This is because they have more control over the sales process and can better manage the risk of customers shopping around for better deals.
Insurers offering brokered sales and direct-to-consumer (D2C) products, however, have a greater concern with churning and stacking.
This is because brokered sales and D2C products often involve fluidless underwriting, making it easier for applicants to compare rates across different insurers.

Consumers may also be more likely to "sprinkle across the industry" to see what they can get through, as one interviewee noted.
In addition, online D2C questions may not be perceived as "real" by consumers, which can lead to a lack of understanding about the implications of anti-selection on premium rates.

Experience Churning by Age
Policies flagged as churning exhibit consistent patterns across all ages above 30, with no noticeable differences.
The prevalence of churning increases with age, but the rate of increase is steady across all ages above 30.
Individuals aged 40+ trigger higher levels of stacking flags relative to the total policies issued within the dataset, especially those aged 50-59.
In fact, 34% of stacking-flagged policies are from people aged 50-59, which is more than double their representation in the full dataset.
Churning and Stacking by Face Amount
Churning and stacking are significant concerns in the insurance industry, and understanding how they vary by face amount is crucial. Policies with $2+ million in face amounts produced disproportionately higher levels of churning flags.
Studying the dataset for churning flags by face amount revealed that the $3-5 million band had the highest level of churning flags. This could be driven by higher commissions for agents at higher face amounts.

Policies with less than $500,000 in face value posed the largest risk of stacking concerns. Industry underwriting practices may be related to this issue.
The most common maximum face amount for accelerated underwriting was $1 million, according to the 2022 Accelerated Underwriting Practices Survey Report from the SOA. This is even lower under guaranteed or simplified issue products.
Technology and Tools
Technology can both enable and combat anti-selection.
Streamlined digital applications and underwriting processes can make it easier to get insurance coverage to people who need it.
However, these innovations can also create holes to exploit.
Insurers need more digital and data-driven tools to prevent anti-selective behavior as the industry modernizes.
The MIB Data Vault is a good example of such a tool, enabling a more robust exploration of anti-selective behavior as more insurers participate in the industry-wide contributory database.
Data and artificial intelligence may enable more efficient ways to flag fraudulent activity in the future, allowing insurers to identify suspect cases and take appropriate action.
Armed with this information, insurers should be able to more easily identify suspect cases and properly price policies.
