An insurance company offers a health plan to a large population, with a single premium calculated on the assumption that the risk of a serious illness is randomly and unknownly distributed among all individuals. A new, widely available genetic test allows each person to privately learn their specific, individual risk for this illness. From the insurance company's perspective, what is the most direct and fundamental problem created by this development?

Adverse Selection in Health Insurance
Initially, a health insurance company and a population of potential customers share the same level of uncertainty about who will need expensive medical care in the future. The company offers a single policy to everyone at a premium based on the average expected cost for the whole group. A new, affordable, and private self-test is then introduced, allowing individuals to accurately determine their personal likelihood of needing this care, without any obligation to share the results. What is the most fundamental change to the market's dynamic caused by the introduction of this test?

The Impact of Private Health Knowledge on Insurance Markets
Imagine a health insurance market where, initially, neither individuals nor the insurance company know who is at high or low risk for a specific costly condition. The insurer offers a single premium based on the population's average risk. A new, private, and affordable test becomes available that allows individuals to learn their personal risk level without having to share the results. Arrange the following events in the logical order they would occur after the test is introduced.
True or False: In a health insurance market where a new technology allows individuals to privately learn their personal health risks (information not available to the insurer), the market becomes more stable because the insurance company can continue to successfully offer a single, average-cost premium to the entire population.
