This English version is a fuller translation and adaptation of the original Korean article, “The Neuroscience of Hate: Why We Struggle to Understand One Another,” for global readers. The article explores the neuroscience of hate, delving into why human brains struggle to understand each other. It is based on the explanations of Professor Kim Dae-sik in “Knowledge Inside Guest Interview EP.134,” which connects brain science, AI, and perception issues to shed light on why humans easily misunderstand and sometimes hate each other.

Key Summary: 5 Perspectives on the Neuroscience of Hate
To understand the neuroscience of hate, we must first accept an uncomfortable fact: we do not see the world as it is but rather through the reality created by our brains. This is why we can look at the same scene and attach completely different meanings to it, or hear the same words and react with different emotions.
Colors Are Not the Same Experience for Everyone
Professor Kim Dae-sik uses colors as an example. The color we call “red” is actually the interpretation by our brains of light wavelengths, and there’s no way to confirm if the “red” I see is the same as the “red” you remember or imagine. We believe we share the same experience because we use the same words, but in reality, our brains may be creating different experiences that we roughly match with the same language.
1. The Brain Does Not See Reality Directly
Professor Kim Dae-sik explains the brain as an entity trapped in the skull, not directly experiencing the outside world but interpreting it through sensory data from our eyes, ears, nose, skin, etc. This explanation is similar to Plato’s allegory of the cave, where we construct reality based on shadows of the actual world, which can always be distorted.
2. The Neuroscience of Hate Begins with the Invisibility of Others’ Inner Worlds
A crucial starting point in the neuroscience of hate is the fact that we cannot directly see into others’ inner worlds. We cannot connect brains like HDMI cables to transfer data. Therefore, we always make estimates when trying to understand others, using facial expressions, tone of voice, behavior, social background, and past experiences to guess their feelings and thoughts.
Groups We Have Not Experienced Become Alienated Easily
Professor Kim Dae-sik shares his experience of living in Europe as an Asian, illustrating how people imagine groups they have not directly experienced in simplistic terms. This shows that hate and prejudice do not always stem from strong malice but can also arise from a lack of experience, imagination, and contact.
3. Why Humans Divide into “Us” and “Them”
The video explains that for humans to cooperate, they had to acknowledge the inner worlds of others. Initially, in primitive conditions, trusting only family or close groups might have been enough for survival. However, with settlement, agriculture, and the expansion of society, cooperation with strangers became necessary.
The Problem Lies in the Fluctuating Scope of Acknowledgment
Even today, we do not treat all people as equals with inner worlds. Political stance, region, gender, generation, nationality, religion, fandom, or taste can easily categorize someone as “someone I don’t understand.” Hate becomes stronger when this categorization solidifies, making it easier to see the other not as an individual but as a group that doesn’t need to be understood.
4. Why AI and Self-Debate Connect to Human Hate Issues
The discussion expands to AI, questioning the criteria by which we treat different beings (objects, animals, humans) differently. The difference lies in judgments about intelligence, self-awareness, and the ability to feel pain. As AI becomes more intelligent, the question arises of how we will understand and control it.
We Still Treat AI as a “Tool”
Currently, we ask AI questions, give commands, and demand results without asking for its consent, treating it like an object or tool. As AI becomes smarter and seems to have abilities like conversation and empathy, this standard may change. This discussion connects to hate issues because we continuously judge who deserves acknowledgment of their inner world.
5. The Analogy of Superintelligent AI: Humans Might Appear Like Ants
A strong analogy in the video is the relationship between humans and ants. Humans do not necessarily hate ants, but when building a house or a road, the presence of an anthill might not be a significant concern. The relationship between superintelligent AI and humans could be similar, warning that as the intelligence gap grows, so does the potential for indifference.
Hate Might Be Less Dangerous Than Indifference
We usually think of hate as a strong emotion, but indifference can be more dangerous socially. When we consider someone or a group not worth our consideration, not out of hate but out of indifference, violence can occur more easily. The neuroscience of hate is thus not just about emotions but also about perception and how we categorize others.
6. The Brain’s Rest: The Judging Brain is a Biological Organ
The latter part of the video discusses sleep and the brain’s rest. Professor Kim emphasizes that the brain operates continuously without rest, unlike electronic devices that can be turned off. The importance of sleep for brain recovery is also highlighted.
A Tired Brain Simplifies More Easily
Sleep is likened to the brain’s garbage collection time, scientifically known to be crucial for memory, recovery, and waste removal. This relates to the issue of hate, as a tired and overloaded brain finds it harder to understand complex individuals and relies more on quick judgments, simple categorizations, and familiar prejudices. Adequate rest is not just a health issue but also a condition for judging others less harshly.
7. What Is Needed for Us to Hate Each Other Less?
In summary, humans are not designed to perfectly understand each other, living in realities created by our brains, unable to directly see into others’ inner worlds, and tending to simplify unfamiliar groups. However, recognizing our limitations allows us to be more cautious. Remembering that our perceived reality is not the only one, that others’ inner worlds are not fully knowable to us, and that unfamiliar groups should not be easily stereotyped can help.
Three Practical Reminders
First, do not believe your reality is the absolute truth; events can be interpreted differently based on individual memories, emotions, and backgrounds. Second, assume that even those you do not understand have their own pains, fears, and reasons. Third, correct your prejudices through actual experiences; abstract images can strengthen biases, while concrete meetings can weaken them.
Conclusion: Acknowledging the Brain’s Limitations Is the First Step to Reducing Hate
The neuroscience of hate does not conclude that humans are inherently bad; rather, it informs us that our brains create reality with limited information and can mistake this reality for absolute truth. Recognizing these limitations allows us to judge others more carefully. Reducing hate begins with humility in our perception, remembering that “my reality might not be the only one.” This simple acknowledgment can make us less prone to hate.
