Some scholars argue that ethnographers are present in their research, occupying a liminal state, regardless of their participant status. Justification for this position is that the researcher as a "human instrument" engages with his/her observations in the process of recording and analyzing the data. A researcher, often unconsciously, selects what to observe, how to record observations and how to interpret observations based on personal reference points and experiences. For example, even in selecting what observations are interesting to record, the researcher must interpret and value the data available. To explore the liminal state of the researcher in relation to the culture, self-reflexivity and awareness are important tools to reveal researcher bias and interpretation.
