Why We Fail As Individuals – Case 1

by James Wallace Harris, 10/7/25

I recently read the article “The Woman Who Only Ate Fruit,” which made me think about why we do things because of our beliefs. The piece was about a Polish woman, Karolina Krzyzak, who died at a resort in Bali because she believed in only eating fruit. It turns out that Bali is a popular destination for people following a vegan lifestyle. Krzyzak followed an even more restrictive diet than veganism, where people only ate fruit.

For some reason, Krzyzak believed that following a fruitarian diet would lead to health and happiness. She had a small following on the Internet as an influencer and hoped to meet other more famous influencers in Bali. However, she soon died after getting there. She was just 27, and weighed 27 kilos, which is slightly less than 60 pounds.

Eating disorders are far from uncommon, but the article didn’t focus on Krzyzak having a medical issue. Instead, it focused on her following influencers on the Internet.

Are eating disorders caused by beliefs or a physiological condition? Are delusions mental or physical? Like many people with an eating disorder, Krzyzak was concerned with her appearance. I believe most people assume culture imposes that on us. But does it?

I don’t know the answers to these questions. Every day, the news brings me stories about delusional people. It makes me feel that everyone is delusional, in one or more ways. I don’t exclude myself.

On the surface, it appears our delusions come from what we believe. And we often judge people’s actions by what they claim to believe. It’s quite easy to say Krzyzak died because she thought only eating fruit would sustain her. But are beliefs really that powerful? History is full of accounts of famines that suggest something different.

People will eat almost anything when they are starving. Wouldn’t Krzyzak’s body have compelled her to eat something rather than starve to death? Are beliefs more powerful than biological drives?

Eating disorders obviously have a biological connection. But what about something that doesn’t? For instance, conspiracy theories. I believe most people think beliefs are completely derived from thinking and thoughts. What if they’re not? What if people prone to conspiracy theories have a biological reason why they embrace delusional theories?

Could there be something in our biology that predisposes us to be more conservative or liberal? I have no idea. I’m just thinking out loud.

If beliefs can change us, why do so few believers change their beliefs? You’d think beliefs would be open to logic and new evidence. But that doesn’t seem to be the case. Many people tried to convince Krzyzak that her beliefs were wrong with strong evidence, but she wouldn’t change.

There is overwhelming scientific evidence that humans are causing climate change, but millions of people refuse to believe that evidence. Is that a logical decision, or a biological reaction? We often use the term “gut reaction” to explain why we think something.

If we’re genetically programmed to perceive reality in certain ways, can any amount of logic or evidence change a person’s perceptions?

I feel like I have changed my beliefs hundreds of times due to new knowledge, and I know other people who claim their beliefs are open to persuasion. Is that a delusion on my part? A possible answer might be that some people are open to change, and others aren’t. I need to research that. I bet scientists have studied that.

I used to believe we could create a sane society if we all worked together to form an enlightened consensus. I doubt that now. The world seems to be going insane despite what we learn. The only way to have hope is to recognize our own delusions and change the way we act. But is that even possible?

I don’t think so if our delusions are tied to our biology.
