The Citation Recency Bias: Rethinking Temporal Standards in Literature Review Practices

This position paper critiques the widespread assumption that literature reviews should prioritize recent sources, often operationalized as a “5-year rule” in academic writing. While recency is valuable for capturing current developments, this practice may inadvertently exclude foundational theories and methodological principles that remain conceptually relevant. To address this issue, the paper introduces Citation Recency Bias, defined as the tendency to privilege newer sources based primarily on temporal proximity rather than functional relevance. Drawing on enduring contributions in research methodology and educational psychology, including measurement theory (Stevens, 1946), reliability estimation through Cronbach’s coefficient alpha (1951), statistical frameworks developed by Fisher (1925) and Cohen (1988), and foundational theories proposed by Bandura (1977) and Vygotsky (1978), the paper argues that many core elements of contemporary scholarship continue to rely on earlier works. Citation Recency Bias is therefore conceptualized as a methodological distortion that may weaken theoretical grounding and conceptual coherence when the publication date is treated as an indicator of scholarly value.
