👉 Birthday research, also known as the "birthday paradox," is a fascinating statistical phenomenon that reveals an unexpectedly high probability of shared birthdays among large groups. While intuitively one might expect this probability to be low, especially with smaller groups, the research shows that for a group of 23 or more people, the likelihood of at least two individuals sharing the same birthday is over 50%. This counterintuitive result arises because as the number of people increases, the number of possible birthday combinations grows exponentially, making collisions (shared birthdays) more probable. The paradox highlights how our everyday assumptions about probability can be misleading when applied to larger datasets.
