When Not Knowing Is Better for Your Mind and Mental Health

In today’s information-driven world, where headlines and notifications are constant, not knowing something may feel like a personal failure. But psychological research suggests the opposite may be true: sometimes, deliberate ignorance can protect your mental health, support better decision-making, and reduce unconscious bias.

A recent review in Current Opinion in Psychology by Fath and colleagues explores the value of what’s called “willful ignorance,” which refers to intentionally avoiding available information.

While this might sound counterproductive, under the right circumstances, avoiding unnecessary information can promote clarity, reduce stress, and improve objectivity.

Why Would Someone Choose Ignorance?

Willful ignorance means deliberately avoiding certain facts, even when they’re easy to access. People often tune out specific details for emotional, social, or cognitive reasons. And often, not very good ones:

1. To justify selfish decisions

A high-earning executive avoids learning how corporate cutbacks harm workers. A meat lover avoids watching videos on factory farming. And a frequent flyer skips reading about the environmental impact of air travel. Why?

Because knowing would make them feel guilty and open to criticism. People often keep themselves in the dark to protect their self-image or justify selfish or unethical behavior. Society tends to judge those who are fully aware of the consequences of their narcissistic actions, so staying in the dark becomes a convenient defense mechanism.

2. To avoid cognitive overload

Another common reason for willful ignorance is mental laziness or fatigue. People may feel overwhelmed by too many options or not know which details matter most.

That’s why we skip the fine print or make rushed decisions, like settling for an apartment that isn’t ideal, just to end the search. We're seeking a shortcut to quick resolution, even if it leads to poorer outcomes.

Can Avoiding Information Be Good for You?

People usually assume that more knowledge leads to better choices. But in some cases, knowing less can actually benefit mental well-being and decision quality:

1. To regulate emotions

Sometimes, more information adds stress instead of clarity. Sidestepping painful truths can serve as a short-term coping strategy when the facts feel emotionally overwhelming or are outside our control.

For example, someone learning that a loved one has a terminal illness may choose not to read the full medical prognosis. A person accepting a dangerous job due to financial hardship might avoid looking up injury statistics. Many people choose not to watch disturbing news about war, disaster, or violence.

Used with care, emotional self-protection is a healthy form of emotion regulation. Over time, though, seeking out relevant facts becomes important for long-term resilience and adjustment.

2. To reduce bias through self-blinding

Self-blinding is a powerful method used to support intelligent and unbiased decision-making. It involves intentionally excluding information that might cloud your judgment.

In science, researchers stay blind to which participants received a real treatment versus a placebo. This helps ensure objectivity. Otherwise, they may unintentionally behave differently (e.g., show expectations of improvement) toward participants in the treatment group and bias the results.

In fields like hiring, law, and academia, self-blinding can mean removing names, photos, or demographic details from evaluations. A hiring manager might assess resumes without seeing any identifying information, allowing them to focus only on experience and qualifications.

By screening out irrelevant data, we can make decisions that are more accurate and inclusive.

Why Willful Ignorance Is Hard, Even When It Helps

Even when willful ignorance has clear benefits, most people struggle to practice it. Two key psychological forces get in the way:

1. Curiosity: Humans are naturally driven to fill in knowledge gaps. Being aware of those gaps without doing anything about them can feel uncomfortable.
2. Overconfidence: Many of us assume that more data helps us make better decisions. But added information often introduces more noise and bias.

How to Practice Smart, Selective Ignorance

When is it actually better not to know something? And how do you resist the urge to always know more?

If curiosity is driving you:

• Ask yourself: “Do I want this information, or do I need it?”
• Focus on what’s essential to make a sound judgment.
• Remember: curiosity can be satisfied later, after you have made a decision.

If overconfidence is driving you:

• Learn how irrelevant facts can sway your thinking. For example, celebrity endorsements or product popularity (“top selling”) may influence you more than you realize.
• Practice journaling your decision process. Track your confidence level, then revisit it later. You may find that limiting unnecessary inputs helps you make a clearer, better choice.

Recognizing Willful Ignorance Can Protect Your Mental Health and Reduce Bias

Willful ignorance has a bad reputation, but under the right circumstances, it’s a smart psychological strategy. It can protect your mental health, support emotional well-being, reduce bias, sharpen focus, and help you make wiser decisions.

If you're unsure whether turning a blind eye is the right choice in a particular situation, consider speaking with a therapist. Gaining an outside perspective can clarify your instincts and improve your decision-making.

In today’s information-saturated world, learning to discern what deserves your attention and what’s better ignored may be one of the most powerful tools for both mental health and effective problem-solving. So take a mindful role in shaping what you absorb, and what you intentionally set aside.
