Could Misinformation Be the Leading Cause of Death?

A Health Threat at the Edge of the Digital Age

The rapid spread of technology and the internet has made information easier to access, but it has also enabled misleading and inaccurate information to spread. There is growing concern that misinformation may reduce life expectancy by negatively influencing health decisions. US Food and Drug Administration (FDA) Commissioner Robert Califf highlighted its impact on public health and suggested it could be the most common cause of death in America.

The FDA commissioner said that although the US produces the world's most advanced drugs and devices, it fails to use these technologies effectively. He suggested that one reason is that Americans make choices based on misinformation .

The Cost of Misinformation: Real-Life Examples

Scientific research shows that technologies developed to save lives, such as COVID-19 vaccines, are rejected because of misinformation. A 2023 paper estimated that inadequate COVID-19 vaccination resulting from misinformation, accounting for both healthcare and economic costs, costs approximately $300 million a day . This shows that choosing not to be vaccinated carries an individual risk and imposes an economic burden on society.

Oncology and Misinformation: A Dangerous Relationship

Misinformation can have serious consequences in vital fields such as oncology . Misleading information about chemotherapy and radiotherapy, for example, can confuse patients who struggle to understand their treatment options and outcomes. Claims circulate online that chemotherapy does more harm than good or that radiotherapy always causes severe side effects. Such misinformation can distort treatment decisions, harming patients' survival and quality of life.

According to recent research on misinformation in oncology:

• Social media posts and blog articles containing misinformation receive higher levels of engagement .
• Of the articles about cancer encountered online, approximately one third contain misinformation , and of those, 77% contain harmful information.

The Cost of Misinformation: US Life Expectancy Has Stalled

The state of US health is deeply troubling. The US Centers for Disease Control and Prevention (CDC) reported that life expectancy had fallen for 2 consecutive years .

Misinformation is seen as an important contributor to stalled life expectancy in America. Various studies measuring its public health effects have made this increasingly apparent.

Monitoring Social Media Is Now a Job in Itself

Misinformation spreads rapidly in the digital age, raising serious concerns, particularly in health. Social media platforms have become a principal source of information on many health topics. However, the spread of unchecked or misleading information can harm public health. Monitoring and correcting misleading health information on social media has now become almost a full-time job in efforts to control the problem and ensure accurate information circulates. To be effective, health authorities and scientists must continually fight information pollution. This is vital to protecting public health and raising awareness.

Could Misinformation Really Be the Leading Cause of Death?

Misinformation can cause serious health problems. This is particularly true of chronic conditions such as cancer, cardiovascular disease and obesity, where misleading information can negatively influence healthy lifestyle choices and treatment decisions.

For example, someone may choose an ineffective or potentially harmful product or treatment to prevent or treat cancer based on misinformation. This can lead them to reject or delay effective treatments, ultimately worsening their health.

Misinformation can also affect healthy lifestyle choices. Someone may underestimate the risks of tobacco or alcohol, or fail to understand the health effects of obesity, based on misleading information. This can make healthy choices harder and ultimately contribute to chronic disease.

However, it is difficult to state definitively whether misinformation is the "leading" cause of death. It can make health risks and outcomes harder to understand, influencing harmful behaviors and treatment decisions. Yet death has many potential causes, and misinformation is only one factor. Others include genetic predisposition, environmental exposures, socioeconomic circumstances and access to healthcare. Calling misinformation the "leading" cause of death may therefore itself be misleading.
