How personal bias can lead to diagnostic errors

On Behalf of | Nov 29, 2025 | Medical Malpractice

Properly diagnosing the cause of a medical condition is a key responsibility for modern physicians. Doctors can draw blood or gather tissue samples for diagnostic testing in specialized facilities. They can refer patients out for imaging tests. They can ask a variety of questions and review the patient’s medical history to reduce the list of potential causes of their symptoms.

When physicians follow the right diagnostic procedures, they can help patients understand their medical challenges and receive the right type of care. Unfortunately, diagnostic errors are incredibly common. In many cases, diagnostic mistakes are the result of a physician letting their personal biases affect their professional conduct.

How can doctors’ personal beliefs influence the care they provide?

Doctors may not believe their patients

Implicit bias affects medical care by influencing how doctors perceive their patients. Previous interactions with other patients and even stereotypes in popular media can impact how doctors interact with different patients.

Doctors may assume that patients from certain backgrounds are more likely to lie to receive medication. Many doctors also allow sex bias to influence the care they provide. They assume that women are more likely to exaggerate their symptoms for attention.

If they cannot objectively observe symptoms in real time, they may not give them the consideration they deserve during the diagnostic process. Unfortunately, the impact of bias diminishes the standard of care that women receive, putting them at increased risk of major diagnostic errors.

Bias can also impact people who belong to a different race, religion or cultural background than the physician treating them. When a doctor lets their personal biases affect their treatment of patients, they could reach the wrong diagnostic conclusion. They could also fail to diagnose the patient.

If a doctor did not listen to a patient and made a diagnostic error as a result, their conduct might constitute medical malpractice. If another physician could have reached the right diagnosis with the same information, then the doctor’s professional failure could be actionable.

Reviewing a recent diagnostic error with a legal professional can help frustrated patients understand their rights. Certain patients are in a strong position to take legal action against doctors to seek compensation for their medical expenses and other losses triggered by malpractice.
