How to Read “二度あることは三度ある”
Nido aru koto wa sando aru
Meaning of “二度あることは三度ある”
“Things that happen twice happen three times” means that when similar events occur twice in succession, there is a high probability that a third occurrence will happen as well.
This proverb is used as a warning that focuses on human behavioral patterns and the cause-and-effect relationships of events. It is particularly often used when failures or problems occur twice in a row, predicting that “surely a third time will happen too” and encouraging people to take preventive measures in advance.
It represents a law of life that the same results will be repeated as long as the fundamental cause has not been resolved. It contains the deep insight that this is not mere coincidence, but that there is inevitability involved.
Even today, it is used when we feel that “the same thing is likely to happen again” in various situations such as mistakes at work, troubles in human relationships, and health problems. By voicing this proverb, it has the effect of making ourselves and those around us aware of the need to break the pattern.
Origin and Etymology
Regarding the origin of “Things that happen twice happen three times,” no clear documentary evidence has actually been found. However, it is believed that the background of this proverb’s creation is deeply connected to the empirical rules and observational skills of the Japanese people.
Since ancient times, Japan has had keen insight into the repetition of events. In an agricultural society, the ability to read patterns in weather and natural phenomena was an important skill directly connected to daily life. The experiential wisdom that if similar events occur twice in succession, a third occurrence is highly likely, must be at the foundation of this proverb.
Since similar expressions can be found scattered throughout literature from the Edo period, it is presumed that it was used among common people at least several hundred years ago. Particularly in the world of merchants and craftsmen, discerning patterns of failure and success could determine the success or failure of business, so proverbs expressing such observational skills may have been treasured.
Additionally, the Buddhist concept of “cause and effect” and the Confucian idea of “the power of habit” may also be in the background of this proverb. The logical thinking that the same causes produce the same results, combined with a deep understanding of human behavioral patterns, may have given birth to this concise and powerful expression.
Usage Examples
- He was late again, but since things that happen twice happen three times, we need to be careful tomorrow too
- I forgot my wallet twice in a row, so since things that happen twice happen three times, I’ll be careful next time
Modern Interpretation
In modern society, “Things that happen twice happen three times” demonstrates its value precisely in this era of data analysis and pattern recognition. With the spread of big data and AI, the concept of “pattern continuity” shown by this proverb could be said to have gained scientific backing.
In corporate risk management, companies analyze past failure cases and strive to prevent the recurrence of similar problems. This is precisely a modern application of “Things that happen twice happen three times.” There is a widespread recognition that problems that occur once, such as system failures, quality issues, and compliance violations, are often rooted in organizational culture and structure, and will inevitably recur without fundamental improvement.
At the individual level, many phenomena of repeating the same patterns can be seen, such as social media controversies, investment failures, and neglect of health management. Modern people are prone to decision fatigue amid information overload and tend to unconsciously repeat the same choices.
On the other hand, modern society also values a “culture of learning from failure,” and the “revenge spirit” of using two failures as experience and turning the third attempt into success is also appreciated. This proverb is being reevaluated as modern wisdom that teaches not only warnings but also the importance of insight to see through patterns.
When AI Hears This
The moment we believe “if something happens twice, it will happen a third time,” our brains unconsciously begin searching for that third occurrence. This is a textbook example of what psychology calls a “self-fulfilling prophecy.”
First, attention bias kicks in. After two failures in a row, we start recognizing even minor mistakes we’d normally overlook as “the third time!” We force events that wouldn’t usually catch our attention into the pattern we expect to see.
Even more fascinating is the behavioral change that follows. When we develop anticipatory anxiety thinking “I’m bound to fail again,” our concentration wavers and we become overly tense, actually making failure more likely. When athletes think “I’ve messed up twice, so the next one’s risky too,” they often do make that third mistake—this mechanism is exactly why.
The same applies to positive events. The expectation that “something good will probably happen again” encourages proactive behavior, which can actually attract positive outcomes.
In other words, this saying isn’t simply a law of coincidence—it’s a “psychological reality” created by human cognition and behavior. By believing in the proverb, we end up creating the very reality the proverb describes. Few phenomena illustrate the complexity of human psychology quite like this.
Lessons for Today
What “Things that happen twice happen three times” teaches modern people is the importance of cultivating an eye for discerning patterns. In our busy daily lives, we tend to get caught up in the events right in front of us, but it’s important to develop the habit of stopping for a moment and noticing “this happened before too.”
This proverb is not simply encouraging resignation. Rather, it teaches us that “now is the chance.” When facing a second failure or problem, it’s the perfect opportunity to reexamine the fundamental causes and work on essential improvements.
In modern society, the pace of change is fast and new problems appear one after another. However, even though they may appear different on the surface, they are often repetitions of the same pattern. If you can notice that there are common factors at the root of relationship troubles, work deadlocks, health problems, and so on, more effective solutions will become visible.
If there are events in your life where you feel “the same thing happened again,” that might be a sign of growth. Only those who notice patterns can gain the power to change those patterns.
