When Scientists Split the Brain
In the 1960s, scientists studied people who had brain surgery to control severe epilepsy. The surgery cut major connections between the two sides of the brain. Researchers discovered that each side could sometimes receive and process information without the other side knowing it.
The Brain Made Up an Explanation
In some experiments, one side of the brain received an instruction, but the side responsible for speaking did not know about it. When the person was asked why they did something, they sometimes gave a reasonable explanation that was not the real reason. The brain was simply trying to make sense of what had happened.
Confabulation Is Not Lying
This is called confabulation, and it is different from lying. A liar knows the truth and chooses to say something false. A person who confabulates usually believes the explanation they are giving because the brain has created a story that seems to make sense.
Ordinary People Do This Too
You do not need a split brain for this to happen. Studies have shown that people can sometimes explain choices they never actually made. This reminds us that we may not always understand our own decisions as clearly as we think we do.
Confidence Is Not Proof
Feeling certain about something does not always mean we are correct. We can be confident and right, but we can also be confident and wrong. That is why evidence matters more than confidence alone.
Did the Surgery Create Two Minds?
The research showed that the two sides of the brain could sometimes work independently after surgery. But scientists still debate whether that means two separate minds were created. What is clear is that our normal sense of being one person depends on different parts of the brain sharing information.
Ask Yourself Why Twice
This research reminds me not to accept every first explanation I give myself. If something makes me unusually angry or upset, I can ask why again. Sometimes an old hurt, fear, or insecurity may be affecting me more than I first realized.
Summary
The brain is very good at creating explanations for what we do. Sometimes those explanations are accurate, and sometimes they are only the best story the brain can create with the information it has. Understanding ourselves requires enough humility to admit that we may not always know the whole reason.
Conclusion
My first explanation does not always have to be my final answer. Sometimes I need to slow down, ask another question, and look more closely at what may be influencing me. Knowing yourself may begin with being willing to say, “Maybe there is more to this than
