You might think that the way you perceive the world is definitive; however, Stanford neuroscientist David Eagleman suggests otherwise. In his exploration of the human brain, Eagleman argues that our perceptions are inherently limited by our experiences, genetics, and cultural upbringing. This article delves into how our brains can form biases and in-groups, and outlines effective methods to expand our worldviews, fostering a more empathetic society.

The Limitations of Human Perception

Biased Reality
As data collection machines moving through the world, we absorb experiences and information that shape our understanding. But these experiences are a fragile mix shaped by location, culture, and personal encounters. Eagleman emphasizes that while it might seem like our perceptions are true reflections of reality, they are often distorted by our subjective experiences.

The Internal Model
We each exist within our unique internal model of understanding, which can limit how we interpret the world around us. This model is influenced by:

• Genetics: Different genetic makeups can affect how we process information and perceive reality.
• Culture: The cultural environment we grow up in defines many of our beliefs and biases.
• Personal Experiences: Individual life experiences further refine our models, often leading us to believe that our perspective is the only valid one.

Understanding this limitation is a crucial step toward broader awareness. Science, literature, and philosophy help provide tools to step outside our perception and recognize that others may see the world differently.

Perceptual Genomics: The Science of Perception

Eagleman introduces the term perceptual genomics, which refers to how subtle genetic differences influence individual perceptions of reality. For instance, consider the ways individuals visualize scenarios or objects in their minds. Two people asked to imagine an ant crawling on a patterned tablecloth might visualize it entirely differently or even not visualize it at all but understand the concept abstractly instead. This variability illustrates how diverse human experience can be.

In-Groups and Out-Groups: Understanding Societal Biases

As social creatures, humans have a tendency to organize into in-groups and out-groups. This evolutionary trait helps establish trust among members of the same group while breeding suspicion towards outsiders. The dynamics of in-group and out-group behaviors can contribute to the lack of empathy for those we consider different from ourselves.

Empathy and Its Limitations

Research reveals that empathy is diminished for out-group members. In a study, participants displayed less brain activity in response to seeing pain inflicted on an out-group member compared to someone from their in-group. This demonstrates how biases shape our emotional responses and hinder our ability to connect with others.

Strategies for Overcoming Bias

To combat these ingrained biases, Eagleman presents several strategies to expand our worldview:

Recognize Personal Biases

Understanding our own biases is the first step in combating them. Self-awareness allows us to identify and challenge preconceived notions about groups of people.

Learn About Dehumanization

Understanding tactics of dehumanization can help protect against developing a dismissive attitude towards out-groups. For example, moral pollution results in associating out-group members with disgust or negativity, impacting how we perceive their intentions.

Complexify Group Membership

Engaging with others on a deeper level can challenge simplistic distinctions. Finding commonalities among people can create bonds that transcend differences. The journey of understanding someone might reveal unexpected similarities, fostering empathy and connection.

The Importance of Expanding Perceptions

Eagleman strongly believes that one of the most important steps in creating a better society is to broaden our internal models of understanding. This broader perspective can be achieved through:

• Traveling: Exposure to different cultures and perspectives can significantly reshape our biases.
• Education: Engaging with literature, scientific insights, and philosophical discussions can challenge our current views.
• Dialogue: Genuine conversations with individuals from varying backgrounds can facilitate mutual understanding.

As we strive to understand our mental models, we begin to realize that our views do not encompass the entirety of experience. Creating a society where empathy thrives hinges on our willingness to engage across perceived boundaries.

In summary, understanding the biases ingrained in our brains is crucial for fostering a more empathetic and understanding society. Recognizing our cognitive limitations can help us take steps toward expanding our perspectives by embracing diverse viewpoints. By incorporating Eagleman’s strategies into our lives, we can actively work to overcome biases that compartmentalize our understanding, ultimately enriching our social interactions and community frameworks.

Take the leap to explore the vast world of human perception. Begin your journey by reaching out and engaging with others from different backgrounds. Awareness and understanding are the keys to overcoming biases, creating a more interconnected and compassionate world.
