Understanding Superstitious Behavior: Insights from Pigeons
Written on
The Historical Context of Superstition
The 14th century was fraught with challenges: the Hundred Years' War raged, peasants sought their place in society, and the Black Death loomed ominously. This plague, which wiped out a third of Europe's population in certain regions, left many in bewilderment.
Amidst this turmoil, the Paris Academy—a leading scientific institution of its time—sought to make sense of what would later be known as the Bubonic plague. After three years of deliberation, their report opened with a sensible, yet ultimately futile, observation:
> "Witnessing phenomena that defy explanation ignites a sense of wonder in the human mind. Yet, after marveling, the wise individual seeks clarity and, in pursuit of understanding, endeavors to uncover the causes behind these astonishing events."
Despite their intellectual pursuits, they lacked the foundational knowledge of microbiology, a field that would only emerge centuries later with the advent of tools like the microscope. Without these instruments, a sound explanation remained elusive, prompting them to devise their own:
> "The root cause of this plague was the alignment of the planets. On March 20, 1345, a significant conjunction of three planets occurred in Aquarius."
The Influence of Astrology and Superstition
Mars, viewed as a harbinger of conflict, was deemed responsible for the violent Black Death sweeping across Europe. Fast forward seven centuries, and similar reasoning may seem absurd, even to the untrained ear. We ridicule the Academy and their fanciful theories, yet do we truly understand how far we've come?
Victor Frankl's poignant memoir, Man’s Search for Meaning, reflects on his harrowing experiences during the Holocaust. He argues that humans can endure immense suffering if they find meaning in their struggles. Nietzsche articulated this sentiment succinctly: "He who has a why can bear any how."
Our innate need to find meaning extends from profound existential inquiries to the mundane aspects of daily life. As a species, we excel at recognizing patterns and assigning significance to them—often to our detriment.
In a world that is fast-paced and intricate, we seldom pause to validate our conclusions. We are inclined not only to perceive nonexistent connections between external events but also to misinterpret the influences of our own actions.
The Rituals of Rainmaking
Rainmaking rituals, designed to invoke precipitation—such as dancing—have been documented across continents. While we may regard such practices with skepticism now, our understanding of weather has evolved significantly. However, the essence of these rituals persists in our daily lives through various forms of superstition.
These beliefs fall under the broader category of cognitive biases—systematic distortions in perception that lead us away from rational judgment. There are numerous cognitive biases, and they are fundamentally ingrained within us. Evolutionary psychology provides insight into why this occurs.
The Role of Cognitive Biases
According to Daniel Kahneman, in his influential work Thinking, Fast and Slow, our brains operate on two systems: a quick, instinctual one and a slower, more deliberate one. In life-threatening situations, quick and efficient heuristics often take precedence over careful reasoning.
Interestingly, humans are not alone in developing biases. Renowned behaviorist B.F. Skinner observed similar patterns in pigeons in 1948, as detailed in his study Superstition in the Pigeon, published in the Journal of Experimental Psychology.
Skinner found that when food was delivered to pigeons at random intervals—unrelated to their behavior—they began to associate their actions with the arrival of food. One pigeon developed a counter-clockwise turning ritual, while another consistently pecked a corner of the cage.
The key takeaway is that the food's delivery was entirely random, yet the pigeons' brains searched for explanations. As the Paris Academy noted:
> "Witnessing phenomena that defy explanation ignites a sense of wonder in the pigeon mind..."
When a pigeon perceives a connection between its actions and the food's appearance, it creates a causal link and performs a "raindance." Skinner noted that even a few coincidental connections between a ritual and favorable outcomes can solidify this behavior, despite numerous instances where no reinforcement occurs.
The Construction of Reality
Our brains shape our perception of reality. Modern neuroscience teaches us that our brains act as agents in the world. When we take a lucky charm to an exam and perform well, think of someone who then contacts us, or do something kind for a stranger only to receive a reward shortly after, we often perceive these events as linked to our actions.
We speak of the law of attraction, karma, or synchronicity, yet we may merely be over-attributing causality to unrelated events.
The Return of Cognitive Biases
As demonstrated by the behavior of the pigeons, our drive to connect external happenings to our actions is intrinsic to our nature. While we may mock the misconceptions of the past, cognitive biases can resurface in our lives. For instance, local newspapers still feature horoscopes, highlighting our ability to imbue vague statements with significant meaning.
This tendency is especially pronounced during uncertain times, as seen with the rise of conspiracy theories related to COVID-19. Though awareness of our biases may not render us immune, it can be beneficial to reflect on our own "raindances."
The Connection Between Bacteria and Weather
In 1979, researcher Russell Schnell from the University of Colorado explored why Kenyan tea plantations experienced frequent hailstorms. His investigation uncovered tiny particles in decaying tea leaves that were remarkably similar to those around which hailstorms formed—those particles proved more effective than artificial cloud-seeding agents.
The unexpected heroes in this scenario were bacteria known as Pseudomonas syringae, which can catalyze ice formation at relatively high temperatures. These bacteria not only affect the plants they feed on but also play a role in weather phenomena. This discovery indicates that human activities that disperse bacteria into the atmosphere can influence rainfall, linking back to both raindancing and pigeon behavior.

The first video, Superstitious Behavior in the Pigeon, delves into how pigeons engage in seemingly irrational behaviors when faced with randomness, shedding light on the psychology of superstition.
The second video, Superstition in the Pigeon, further examines the fascinating connection between animal behavior and human cognitive biases, illustrating our shared tendencies in the face of uncertainty.
