When I first started digging into duplicate review fatigue rate statistics, I didn’t expect it to feel so much like untangling a messy drawer full of mismatched socks — you keep finding the same patterns over and over, just slightly crumpled in different ways. Whether it’s in software bug tracking, academic peer reviews, or support ticket systems, duplicates sneak in and pile up, demanding the same mental energy again and again. For reviewers, this isn’t just a minor annoyance; it’s a constant drain that slows progress, clouds judgment, and sometimes makes you dread opening the queue at all. Over time, the repetition becomes more than a data problem — it becomes a human one, where burnout quietly takes root. Understanding these patterns, and quantifying them, is the first step toward making review work feel purposeful again instead of like an endless loop.
