Introduction
For over sixty years, the Eurovision Song Contest has captivated a global audience, drawing millions of viewers each May. Since its inception in 1956, the contest has evolved through countless tweaks to its format, a flood of imitative acts, and an ever-growing set of regulations. Yet, despite this meticulous structuring, Eurovision remains famously unpredictable—a phenomenon that continues to baffle fans and analysts alike.
This unpredictability is not merely anecdotal; it is deeply embedded in the contest's DNA, making it a fascinating case study for researchers. With a publicly available, well-documented archive of songs, voting patterns, and rule changes spanning decades, Eurovision offers an unparalleled opportunity for data-driven social science. Why, then, does the contest resist predictability after nearly seventy years?
