research saturation

Research saturation occurs when gathering more data or studying a topic no longer provides new insights or information. It's the point at which additional research confirms what’s already known, indicating that enough evidence has been collected to fully understand the subject. Recognizing saturation helps researchers determine when their work is comprehensive, avoiding unnecessary repetition and conserving resources. Essentially, it’s the stage where further investigation yields diminishing returns because the key findings and patterns have already been identified.
