Recency Bias

Identified as a cognitive bias by psychologists Amos Tversky and Daniel Kahneman in the early 1970s during their pioneering work on judgment heuristics. The phenomenon itself was recognized far earlier—Roman historian Livy described it in the 1st century BC in his preface to History of Rome, noting people's tendency to focus on recent events over historical ones. Recency bias is distinct from but related to the "recency effect" in memory studied by Hermann Ebbinghaus.
