Saturation Point Is Reached When the Researcher, Though Continuing to Explore

Saturation point is reached when the researcher, though continuing to explore the phenomenon with participants in the research, no longer hears any new thoughts, feelings, attitudes, emotions, intentions, etc. This is saturation point, the researcher is 'saturated' with knowledge on the topic and continuing to engage participants would not be useful, necessary, or ethically sound, as engaging further participants in the research will not add in any way to the knowledge generated.
