Not to mention that in the wider world, the most common types of processes follow a Zipfian distribution[1]. It think this misunderstanding comes from undergraduate statistics courses teaching you all about normal and uniform distributions, while most students are unlikely to learn the limits and general inapplicability of that model unless they go into research. Most people's first encounter with real statistics is bell curves. Not to mention that the central limit theorem lulls you into a false sense of security that "at the end of the day" everything will look normal.
