The qualitative research has multiple subjectivities. However, if we get the essence of the phenomena as in the transcendental phenomenology, can we say it being a single reality?
In qualitative research, the goal is often to explore and understand the multiple subjectivities and perspectives of the participants. Therefore, it is not typically appropriate to reduce the findings to a single reality or essence that is completely independent of the individual experiences and perspectives of the participants.
Additionally, it is important to recognize that the researcher's own subjectivity and perspective can also influence the findings and interpretation of qualitative research. Therefore, it is important to be transparent about the researcher's perspective and acknowledge the potential limitations and biases in the findings. Overall, while transcendental phenomenology can be a useful approach for understanding the essential structures of subjective experience, it is important to recognize and respect the multiple subjectivities and perspectives of the participants in qualitative research.
This seems essentially a philosophical question as to what traditions typically refer to as nonduality. Some phenomenological traditions refer to a noumenon behind phenomena of manifest reality.
There is no single reality since in qualitative research this reality is analyzed from different points of view, ways of thinking, culture, description of the facts and depends on what is thought and what is felt.
