WASHINGTON — Most Americans believe health insurance profits and coverage denials share responsibility for the killing of UnitedHealthcare’s CEO — although not as much as the person who pulled the trigger, according to a new poll.

In the survey from NORC at the University of Chicago, about 8 in 10 U.S. adults said the person who committed the killing has “a great deal” or “a moderate amount” of responsibility for the Dec. 4 shooting of Brian Thompson.

Despite that, some have cast Luigi Mangione, the 26-year-old suspect charged with Thompson’s murder, as a heroic figure in the aftermath of his arrest, which gave rise to an outpouring of grievances about insurance companies. Police say the words “delay,” “deny” and “depose” were scrawled on the ammunition investigators found at the scene, echoing a phrase commonly used to describe insurer tactics to avoid paying claims.

UnitedHealthcare has said Mangione was not a client.

About 7 in 10 adults say that denials for health care coverage by insurance companies, or the profits made by health insurance companies, also bear at least “a moderate amount” of responsibility for Thompson’s death. Younger Americans are particularly likely to see the murder as the result of a confluence of forces rather than just one person’s action.

Americans See a Wide Range of Factors Contributing to UHC CEO’s Killing

The poll finds that the story of the slaying is being followed widely. About 7 in 10 said they had heard or read “a lot” or “some” about Thompson’s death.

Multiple factors were seen as responsible. About half in the poll believe that at least “a moderate amount” of blame is rooted in wealth or income inequality, although they did not think other factors like political divisions in the U.S. held the same level of responsibility.

Patients and doctors often complain about coverage denials and other complications interfering with care, especially for serious illnesses like cancer and amyotrophic lateral sclerosis, or ALS. Insurance industry critics frequently point to company profits in questioning whether the interests of patients are their top focus.

UnitedHealthcare made more than $16 billion in profit last year, before interest and taxes, on $281 billion in revenue. Insurers frequently note that most of the revenue they bring in goes back out the door to pay for care. UnitedHealthcare said this month that it pays about 90% of medical claims when they are submitted. The insurer has not provided details about how many claims that involves.

For Young People, Blame Is Spread Equally Between Insurers and the Killer

Americans under 30 are especially likely to think a mix of factors is to blame for Thompson’s death. They say that insurance company denials and profits are about as responsible as Thompson’s killer for his death. About 7 in 10 U.S. adults between 18 and 29 say “a great deal” or “a moderate amount” of responsibility falls on profits made by health insurance companies, denials for health care coverage by health insurance companies or the person who committed the killing.

Young people are also the least likely age group to say “a great deal” of responsibility falls on the person who committed the killing. Only about 4 in 10 say that, compared with about 6 in 10 between 30 and 59. Roughly 8 in 10 adults over 60 say that person deserves “a great deal” of responsibility.

About two-thirds of young people place at least a moderate level of blame on wealth or income inequality, in general.

People under 30 are more likely to place blame on the media, with 54% saying that compared with about one-third of older adults.

About 3 in 10 Struggled With Coverage From Health Insurance in the Last Year

Frustrations with health insurers, coverage and the complicated U.S. health care system have been simmering for years among patients.

About 3 in 10 Americans say they have had a problem getting coverage from their health insurer in the last year, whether those involved problems finding a suitable provider in-network, a claim getting denied or issues getting prior authorization or insurer approval before care happens. These struggles are more prevalent among Americans under 60.

UnitedHealthcare says prior authorizations help eliminate waste in the system and let people know whether care will be covered before it is delivered. It says less than 2% of the insurer’s customers experience a denial of care from prior authorizations annually.

Roughly 3 in 10 in the poll say immediate family or close friends have experienced problems getting coverage from their health insurer in the last year. Americans under 30 are among the most likely to say they don’t have health insurance.

Most Americans get health coverage through their job or by purchasing individual policies. Separate, government-funded programs provide coverage for people with low incomes or those who are age 65 and over or have severe illnesses or disabilities.

The poll of 1,001 adults was conducted Dec. 12-16, 2024, using a sample drawn from NORC’s probability-based AmeriSpeak Panel, which is designed to be representative of the U.S. population. The margin of sampling error for adults overall is plus or minus 4.2 percentage points.
