The principle that each study must have similar methodologies is crucial when conducting a meta-analysis of research studies because this ensures that the results can be compared and aggregated meaningfully. Meta-analysis aims to synthesize findings from various studies to derive a comprehensive understanding of a particular topic or effect. When the methodologies vary significantly, the results may reflect differences in design, sample size, measurement tools, or interventions, which can lead to misleading conclusions.

Having similar methodologies allows researchers to evaluate the consistency of findings across studies, enhances the reliability of the overall conclusions drawn from the meta-analysis, and strengthens the generalizability of the results. While other factors, such as publication status or focus on the same population, may affect the robustness of the analysis, the compatibility of methodologies is foundational for a valid and coherent synthesis of research findings.
