Masashi Kishimoto is a Japanese manga artist best known for creating the globally acclaimed manga and anime series Naruto
In 1997, a young Japanese artist spent long nights in a small studio working on a story about a lonely boy who carried a powerful monster inside him. At the time, the idea went against what most manga publishers wanted. Main characters were expected to be easy to like, not social outcasts with painful pasts. Some people believed the story was too dark to succeed in a popular magazine.That artist was Masashi Kishimoto. Two years later, Naruto began serialization in Weekly Shōnen Jump and went on to sell more than 250 million copies worldwide. Looking back on the fine line between failure and success, Kishimoto summed it up with a simple observation:”The difference between insanity and genius is measured only by success and failure.”His words point to the way society judges people who take risks. When someone pursues an unusual idea and fails, they are often called reckless, unrealistic, or even crazy. But if that same idea succeeds, people suddenly describe the creator as a genius or visionary. Kishimoto’s quote reminds us that public opinion often depends more on the final result than on the idea itself.
Kishimoto’s difficult road to success
Masashi Kishimoto was born in Okayama Prefecture in 1974. As a child, he loved manga and anime, especially Doraemon and Akira Toriyama’s Dragon Ball. But becoming a professional manga artist was far from easy.After winning Shueisha’s Hop Step Award in 1995 for his one-shot manga Karakuri, Kishimoto spent several years submitting new ideas to editors. Many were rejected before he finally found success with Naruto.At the time, the manga industry was highly competitive. Weekly Shōnen Jump relied on weekly reader surveys, and series that ranked poorly for several weeks could be cancelled almost immediately.Even then, Kishimoto refused to simplify his story. He wanted characters with tragic pasts, morally complex villains, and storylines that developed slowly over time instead of following simple good-versus-evil formulas. If Naruto had failed early on, many people would likely have called his approach unrealistic. Because it became a huge success, those same creative choices are now seen as one of the series’ greatest strengths.Although similar ideas have been expressed by writers such as Alexandre Dumas and Lord Byron, Kishimoto’s version reflects his own experience working in Japan’s highly competitive manga industry.
Why success changes how we judge ideas
Kishimoto’s quote reflects a well-known concept in psychology called outcome bias. This is the tendency to judge a decision based mainly on how it turns out rather than whether it was a reasonable decision at the time.A similar idea appears in the philosophy of William James, one of the founders of pragmatism. In Pragmatism (1907), James argued that people often judge ideas by their practical results rather than by their original value.History offers many examples. Thomas Edison tested thousands of materials while trying to invent a practical light bulb. Before he succeeded, many people viewed his repeated failures as stubbornness. After his invention worked, those same efforts became a symbol of determination.The opposite also happens. Many inventors and creators who took similar risks but failed are largely forgotten today, even if their ideas were just as bold.In reality, the daily lives of a genius and someone whose ideas fail can look very similar. Both may spend years working alone, ignoring criticism, and focusing completely on a goal. Society usually decides whether to call them brilliant or foolish only after the outcome is known.
Why the quote still matters today
Kishimoto’s observation remains relevant in today’s world, especially in industries such as artificial intelligence, biotechnology, and space technology.Many startup founders with unusual ideas are dismissed at first because their plans seem unrealistic. Yet when those ideas succeed, the same people are praised for thinking differently.A well-known example is SpaceX. In its early years, many experts doubted that reusable rockets could land vertically after launch. Once the company repeatedly proved it could be done, the idea quickly became accepted across the space industry.Psychologist and Nobel Prize-winning economist Daniel Kahneman also explored this pattern in Thinking, Fast and Slow. He explained that people often praise bold decisions when they lead to success but criticize the very same decisions when they end in failure.Understanding this bias can help people judge ideas more fairly. Instead of relying only on results, it is often more useful to ask whether an idea was well thought out, carefully planned, and based on sound reasoning.Before Naruto became one of the world’s best-selling manga series, Kishimoto spent years dealing with rejection, failed ideas, and long hours of work with little recognition. His quote is a reminder that many creative ideas are judged only after they succeed, not while they are still taking shape. Go to Source
