26
The emphasis is on AI as a tool to empower, rather than replace, underwriters. While AI handles process execution for standard cases, human expertise remains indispensable for navigating nuanced risks, building long-term broker relationships, and applying judgment, empathy, and innovation.
4.2 Job Outlook and Required Skillsets in an AI-Driven World
The job outlook for insurance underwriters reflects this evolving landscape. The U.S. Bureau of Labor Statistics projects a 4% decline in employment for insurance underwriters from 2023 to 2033, equating to a loss of approximately 4,700 jobs.
Despite this projected decline in raw numbers, an average of about 7,800 job openings for insurance underwriters are anticipated each year over the decade. These openings are expected to result from the need to replace workers who transfer to other occupations or exit the labor force, such as for retirement.
The skills required for underwriters in an AI-augmented world are therefore transforming. While traditional underwriting expertise remains valuable, new competencies are becoming paramount:
Technological Literacy: Underwriters need to understand how AI tools function, how to interpret AI-generated insights, and when human intervention or override of automated decisions is necessary.
This includes familiarity with big data concepts and the capabilities of machine learning and predictive analytics.12 12 Analytical Thinking and Data Interpretation: The ability to critically analyze data, identify patterns, and derive meaningful conclusions from complex datasets, often augmented by AI, will be crucial.
Underwriters will leverage AI for deeper risk analysis rather than manual data crunching.12 33 Creative Thinking and Problem-Solving: As routine tasks are automated, underwriters will increasingly focus on complex, nuanced cases that require human judgment, creative solutions, and an entrepreneurial mindset.
This involves understanding, selecting, and pricing complex risks that AI cannot yet fully handle.7 7 Communication and Relationship Building: With AI handling much of the data processing, underwriters will have more time to engage with brokers and clients, build stronger relationships, and provide strategic advice.
This emphasizes the human element of empathy and trust in the underwriting process.26 12 Flexibility and Adaptability: The rapidly evolving technological landscape demands that professionals be resilient and agile, continuously learning new skills and adapting to changing workflows.
7
The future of underwriting is collaborative, connected, and data-driven.

5. Ethical and Regulatory Considerations in AI Underwriting
The rapid integration of AI into insurance underwriting, while offering immense benefits, also introduces significant ethical and regulatory challenges that demand careful navigation to ensure fairness, transparency, and consumer protection.
5.1 Algorithmic Bias and its Implications
One of the most frequently discussed and critical ethical challenges is the potential for algorithmic bias to be embedded within AI tools and the underlying data or language models upon which their knowledge base is formed.
Examples of how bias can manifest include:
Historical Data Skew: A financial services AI system trained on 70 years of data was found to be biased against women because they were not allowed to own credit cards until 1974, leading to unfair credit assessments.
Similarly, medical records or pharmacological studies historically based predominantly on men can introduce bias into health insurance models.36 36 Proxy Factors: Even if an AI-driven pricing model avoids using protected characteristics like race, gender, or income as direct variables, it may inadvertently use proxy factors that are highly correlated with these characteristics. This can lead to unfairly penalizing individuals based on attributes that are proxies for socio-economic status or other protected details, resulting in discriminatory pricing outcomes.
For instance, an auto insurance algorithm trained on data correlating accidents with a specific demographic group rather than actual driving behavior could unfairly charge higher premiums to individuals in that group.37 38 Underestimation of Risk: An insurer using an ML model to predict life insurance mortality rates might inadvertently incorporate biased data that skews towards affluent applicants. This could lead the algorithm to underestimate risks for certain demographic groups, resulting in improper risk assessments and potentially unsustainable pricing strategies.
38
The insurance industry’s perspective, as articulated by the National Association of Mutual Insurance Companies (NAMIC), views the concept of “algorithmic bias” as potentially incongruent with how insurance is priced and functions.
To mitigate the risk of AI bias, insurers must adopt a multi-pronged approach:
Diverse Training Datasets: Utilizing diverse and representative training datasets is crucial to prevent the reinforcement of historical biases.
3 Bias Audits and Monitoring: Regular audits of AI models are necessary to detect and correct potential biases in decision-making.
3 Constraint Implementation: Adding constraints during AI model training can prevent discrimination and ensure fair outcomes across different demographic groups.
38 Sensitive Feature Removal: Removing or de-emphasizing sensitive attributes (e.g., race, gender, age) from input data can prevent unwanted biases from influencing model predictions.
38
5.2 Data Privacy and Regulatory Frameworks
The reliance of AI-driven decision-making on vast amounts of personal data raises significant concerns about customer privacy and data protection.
Regulatory bodies worldwide are actively responding to these challenges. The European Union’s General Data Protection Regulation (GDPR), which came into effect in 2018, requires companies to obtain explicit consumer consent (“opt-in”) for the collection and use of personal data.
State insurance regulators, particularly through the National Association of Insurance Commissioners (NAIC), are closely monitoring the impact of innovative technology and consumer data use on the existing regulatory framework.
Key NAIC initiatives and regulations related to data privacy and AI include:
Model Bulletin on the Use of Artificial Intelligence by Insurers: Adopted in December 2023, this bulletin provides guidelines for responsible AI use, reminding insurers that AI-driven decisions must comply with all applicable insurance laws and regulations.
It sets expectations for AI governance and outlines the information regulators may request during investigations.8 8 Privacy Protections (H) Working Group: This group is actively drafting amendments to modernize the NAIC’s Privacy of Consumer Financial and Health Information Regulation (#672), which is several decades old and does not reflect current technological advancements in data collection.
Proposed amendments cover consumer rights, consent, notification, third-party contractual obligations, and limits on the sale and disclosure of sensitive personal information.40 A full draft is expected by early 2026.40 40 Third-Party Data and Models (H) Task Force: Formed in 2024, this task force is developing a regulatory framework for the use of third-party AI data and models by insurance companies.
8
Some cyber insurers are also beginning to incorporate specific language into their policies addressing AI risks, either providing affirmative coverage for AI-related cyberattacks or including exclusions for certain AI events.
5.3 Transparency and Explainability of AI Decisions
For insurers to fully trust and adopt AI, and for consumers and regulators to accept its use, there must be mechanisms that allow stakeholders to interpret complex AI decision-making processes.
Explainable AI (XAI), is crucial for managing AI risk and building trust, particularly in high-stakes areas like claims assessment and underwriting.
XAI provides insights into how AI models arrive at their conclusions, allowing insurers to detect and correct potential biases, provide clear explanations to customers and regulators, and strengthen the overall trust and adoption of AI technologies.
The lack of transparency in AI’s “black box” decision-making can lead to a significant loss of trust if left unaddressed.
The urgency to “get AI right” is palpable within the insurance industry, which traditionally lags in technological advancement due to its risk-averse nature.
