Understanding Our Perception of Patterns
In July of this year, three airplane accidents occurred within just eight days. The aftermath was a surge of anxious posts on social media, many expressing concerns like, “What is happening in the skies?” This was particularly unsettling for me, as I was scheduled to fly to San Francisco the following day. The narrative that flying was “more dangerous than we thought” certainly heightened my anxiety.
But should I have been concerned? While three plane crashes in such a short time frame may seem alarming, David Thornton, a risk analysis expert at Cambridge University, assures us that statistically, such occurrences are not as rare as they appear. In fact, the likelihood of experiencing three crashes within any decade is about 60%, which is surprisingly more common than one might think.
The Nature of Randomness
One key insight is that true randomness does not manifest in the ways we often expect. Real random events tend to produce clusters (for a detailed statistical explanation, see related articles). For instance, stars in the night sky, though randomly distributed, frequently form recognizable constellations. Similarly, if plane crashes are random over ten years, it’s not unusual for two or three to happen in close succession.
When Apple first introduced the iPod Shuffle, users complained that the “random shuffle” feature did not seem random enough, as they occasionally heard the same song back-to-back. Ironically, the original shuffle function was genuinely random, meaning it could play the same track multiple times in a row. Apple later adjusted this feature to create an illusion of randomness, which users found more satisfying. This example demonstrates how our perception of randomness can be skewed.
The Psychology Behind Pattern Recognition
The anxious social media reactions reveal more about human psychology than about the actual risks of flying. Why do we struggle to recognize true randomness? Why do we see patterns and assume there must be some underlying cause? One explanation lies in our inherent cognitive bias towards pattern recognition. Our brains are wired to identify connections, even in random events, and to attribute intentionality to occurrences that are random.
An evolutionary perspective helps explain this tendency. Imagine living in prehistoric times and hearing a rustling in the bushes. You could be facing a predator or merely the wind. If you flee and it turns out to be harmless, you might feel foolish. Conversely, if you ignore it and it’s a predator, the outcome could be fatal. Those who err on the side of caution are more likely to survive and pass on their genes.
Another reason we misinterpret randomness is our focus on clusters while neglecting the broader context. For example, if you roll a die five times and get five sixes, it seems remarkable. However, if you roll the die a thousand times, that same sequence loses its surprise factor. Similarly, if you randomly approach someone on the street and find an immediate connection, it seems fated, but consider the multitude of encounters that preceded that moment.
Though our tendency to see patterns may have been advantageous in ancestral environments, it can lead to unnecessary anxiety in contemporary life. This was certainly true for me during that flying episode.

Summary
In summary, our tendency to perceive patterns in randomness stems from both evolutionary psychology and cognitive biases. This inclination can lead to overestimating risks, such as the perceived dangers of flying after a series of accidents. While it’s essential to be aware of risks, understanding the nature of randomness can help alleviate unnecessary fears.
