Confirmation Bias

In today’s digital age, information bombards us from every direction. We’re constantly exposed to news articles, social media posts, and advertisements, shaping our perceptions and influencing our decisions. However, a lurking danger lies amidst this vast sea of information – confirmation bias. Understanding this concept is crucial, especially in high school, where critical thinking skills are sharpened, and opinions are formed.

Confirmation bias is our urge to seek, interpret, and remember information that confirms our existing beliefs or hypotheses. Essentially, we cherry-pick evidence that aligns with our thoughts while ignoring or dismissing contradictory evidence. It’s like wearing tinted glasses that filter out anything that doesn’t match our preferred color.

Here is an example: Sarah, a high school student, believes that video games are harmful and lead to increased aggression in players. Whenever she reads news articles or studies that support this view, she shares them with her friends and family, reinforcing her belief. However, when she comes across research suggesting no significant link between video games and aggression, she quickly dismisses it as flawed or biased. Sarah’s confirmation bias makes her selectively accept information that aligns with her preconceived notion while ignoring or discrediting evidence. As a result, she needs to consider alternative perspectives and overlook the issue’s complexity, maintaining her biased view of video games.

Why is this an important topic? Well, imagine you’re researching a controversial issue like vaccines. If you’re already convinced that vaccines are a hoax, you might selectively seek out articles or studies that support your belief, dismissing the overwhelming scientific consensus. This keeps false information going and makes it harder to find answers to important worldwide problems.

Confirmation bias plays a big part in spreading false information, especially with everything we see online. We prefer things that agree with what we already think. This means we might ignore or push away things that don’t fit our views, making it easy for wrong ideas to keep going around. For instance, if Sarah from our previous example believes that video games are harmful, she will probably look for and share things online that supports what she thinks, even if it’s not true. This keeps the wrong info spreading, especially when it’s shared in groups where everyone already feels the same way. Understanding confirmation bias is essential to be more thoughtful about the stuff we see online and stop fake news from spreading too much.

Confirmation bias can show up in how high school friends interact, too. Picture this: a group of friends talking about something that happened at school. If one friend says they didn’t like it, others might agree just to keep the peace and stay friends. This happens even if they don’t really agree deep down. It’s the same tinted glasses everyone wears that make them see things the same way. This can stop people from speaking up about what they really think or considering different viewpoints, all because they want to fit in with their friends.

So, how do we prevent confirmation bias? Firstly, awareness is critical. Recognizing that we all have biases and actively questioning our own beliefs can help mitigate their influence. Encouraging diverse perspectives and seeking out information from reputable sources also helps broaden our understanding and reduces the likelihood of falling into confirmation bias traps.

What are common mistakes associated with confirmation bias? One common mistake is relying too heavily on anecdotal evidence or personal experiences to support our beliefs. Just because something is true for us doesn’t mean it’s true for everyone. Additionally, we may overlook or downplay evidence that challenges our beliefs, leading to a skewed view of reality.

Fighting confirmation bias requires effort. Things you can do, that are effective include:

  • Actively seeking out the other sides views.
  • Engaging in discussions.
  • Fact-checking information before accepting it as truth.

Promoting an environment where people are open to different ideas and think critically in our schools and communities can help encourage more honest and insightful conversations.

Statistics related to confirmation bias paint a sobering picture. Studies have shown that confirmation bias affects various aspects of our lives, from politics to health decisions. For example, research conducted by the Pew Research Center found that people are more likely to believe and share information that aligns with their political views, regardless of its accuracy. Similarly, confirmation bias can influence medical decisions, leading individuals to seek information supporting their preferred treatment while ignoring potentially more effective alternatives.

Confirmation bias can also impact our decision-making processes, especially when it comes to important life choices such as career paths or relationships. For instance, imagine a high school senior, Taylor, who has always dreamed of becoming a doctor because their parents are doctors. Taylor might selectively seek out information that confirms their belief that medicine is the right career path for them, while ignoring evidence that suggests they might be better suited for a different profession. This bias can limit Taylor’s exploration of other career options and lead to dissatisfaction or regret in the long run.

What can happen if we fall to confirmation bias? The consequences can be dire. In politics, it can deepen societal divides and hinder constructive dialogue. In the world of science, it can slow down progress and new discoveries by ignoring evidence that doesn’t fit with what we already believe.. In personal relationships, it can lead to misunderstandings and conflicts as we fail to consider alternative perspectives.


To sum up, confirmation bias is a big deal that affects what we think, how we decide, and how we relate to others. Knowing about it, recognizing our own biases, and listening to different viewpoints can help us deal with it better and make our society more open-minded and well-informed. High school is not just about learning facts; it’s about thinking critically and navigating the complex world of information with integrity.
