Myside bias refers to the tendency of people to favor information that confirms their existing beliefs while dismissing information that contradicts them. Imagine you're a soccer fan who believes that your team is the best. You'll likely focus on the stats that show your team in a good light, while ignoring any stats that suggest otherwise. This bias can affect how we think, make decisions, and understand the world around us.

Why Do We Experience Myside Bias?

Myside bias isn't just a quirky trait; it's deeply rooted in how our brains work. As we interact with our environment, our brains learn which information is useful and which isn't. Think of it as a mental filing system where we store information that fits our beliefs and toss out anything that doesn't. This process can be described as a form of learning, whereby we get positive reinforcement for believing certain things and negative reinforcement for others.

The Role of Reinforcement Learning

Reinforcement learning is a way our brains help us learn from experiences. Picture a dog that learns tricks: it gets a treat for sitting, which encourages it to sit again. Similarly, when we encounter information that aligns with our beliefs, our brains reward us with positive feelings. This reinforces our existing beliefs, making us less likely to accept contradictory information.

How Myside Bias Affects Our Lives

Myside bias influences many aspects of life, from daily decisions to major life choices. It can affect how we form opinions on political issues, scientific findings, and even personal relationships. Whether we're reading the news, discussing politics with friends, or even choosing products to buy, our biases can shape what we perceive as truth.

In Politics

In politics, myside bias can lead to divisions among individuals and groups. People often align themselves with political parties that reflect their beliefs. Consequently, they may ignore or reject facts that contradict their political leanings. This can create an environment where misinformation spreads, and people become more polarized in their opinions.

In Science

In scientific debates, myside bias can also be problematic. Scientists may favor research that supports their hypotheses while downplaying findings that oppose them. This can lead to stagnation in scientific progress, as opposing views are not given the fair consideration they deserve.

In Personal Relationships

Even in personal relationships, myside bias can rear its head. When friends or family argue, they often focus on points that support their stance while ignoring counterarguments. This can lead to misunderstandings and unresolved conflicts.

Recognizing Myside Bias

Being aware of myside bias is the first step toward mitigating its effects. Here are some practical ways to recognize when it may be influencing your thoughts:

  1. Question Your Assumptions: Whenever you encounter new information, take a moment to reflect on your initial reaction. Are you automatically accepting or rejecting it based on your beliefs?

  2. Seek Diverse Perspectives: Make an effort to consume a variety of viewpoints, especially those that contradict your own. It can be uncomfortable, but it helps in seeing the bigger picture.

  3. Engage in Open Discussions: Discussing ideas with people who hold different views can shine a light on your biases. It encourages Critical Thinking and can lead to a better understanding of complex issues.

The Science Behind Myside Bias

Recent studies have shown how myside bias is grounded in brain activity. Certain areas of the brain are activated when people process information that aligns with their beliefs. Conversely, when they encounter opposing viewpoints, the brain's response can be less enthusiastic.

The Brain's Learning Systems

The brain operates through multiple learning systems that can influence how we perceive information. One system focuses on rewards and punishments, while another is more analytical. Myside bias often arises when the reward-based system overshadows the analytical one, leading us to favor confirming information without critically evaluating it.

The Impact of Information Overload

In today's world, we are inundated with information daily. This constant stream can amplify myside bias. With so much content available, it becomes easy to cherry-pick data that supports our beliefs while conveniently ignoring anything that doesn't.

Confirmation in the Digital Age

Social media platforms can exacerbate myside bias by creating echo chambers. These are environments where users are only exposed to information that aligns with their views. Algorithms curating content based on previous interactions can support this bias, making it difficult for users to encounter diverse opinions.

Strategies to Combat Myside Bias

While myside bias is a common behavior, there are effective strategies to counter it:

  1. Practice Critical Thinking: Cultivating a critical mindset can help challenge existing beliefs. Ask yourself why you hold certain opinions and whether they're based on solid evidence.

  2. Stay Informed: Regularly update yourself on various topics from reliable sources. This can create a well-rounded perspective that incorporates multiple viewpoints.

  3. Embrace Cognitive Dissonance: Accepting that conflicting information can exist side by side is essential. Cognitive dissonance is the mental discomfort experienced when faced with contradictory beliefs. Instead of avoiding it, embrace the discomfort as a part of growth.

Conclusion

Myside bias is a pervasive aspect of human cognition that affects how we interpret information. By recognizing its presence and employing strategies to combat it, we can work towards a more balanced and informed perspective. This will help us navigate the complex world of ideas and beliefs, ultimately leading to better decision-making and interpersonal understanding. The journey may be challenging, but it's a worthwhile endeavor to broaden our horizons and foster a more open-minded approach to the world around us.

Title: Mice-side bias: Deliberative decision making in a model of rule revision reveals 'myside' confirmation bias-like cognitive processes in mice.

Abstract: Confirmation or myside bias--over-valuation of novel information which confirms previously internalized cognitive content (prior beliefs, rules of conduct, etc.) and corresponding under-valuation of disconfirming novel information--constitutes a serious obstacle to adaptive revision of our beliefs, especially in ambiguous or complex epistemic environments. Indeed, myside bias has become a particularly pernicious fact of societal cohesion, contributing to the propagation of fake news, to social polarization, and even to the replication crisis in experimental science. By contrast, relatively little is understood about either its neurocognitive underpinnings or its evolution, one reason for this being that the potential presence of myside bias-like tendencies in non-human animals has never been directly tested. Hence, in order to advance research in both of these directions, we designed a novel mouse model of everyday-like rule revision such that the dynamic model environment would be sufficient to call out myside bias-like behaviors providing that mice did indeed possess the particular kind of competing neurocognitive processes necessary for it to manifest. Here, we both validate that model and provide the first behavioral descriptions of myside confirmation bias-like deliberative profiles in a non-human animal. Notably, we observe that this bias does not manifest in a merely unreflective or heuristic/ system 1 manner but rather also emerges through and indeed increases deliberative behaviors, especially in contexts of low representational resolution. Several other parallels with findings from human studies of myside bias are also detailed in the discussion.
