DISADVANTAGES OF PHENOMENOLOGY
The disadvantages of using phenomenology for your research are:
The subjectivity of the data leads to difficulties in establishing reliability and validity of approaches and information.
It is difficult to detect or to prevent researcher induced bias.
There can be difficulty in ensuring pure bracketing - this can lead to interference in the interpretation of the data.
The presentation of results - the highly qualitative nature of the results can make them difficult to present in a manner that is usable by practitioners.
Phenomenology does not produce generalisable data.
Because the samples are generally very small, can we ever say that the experiences are typical?
The original Husserlian/Heideggerian texts were written in German, and translations of words could lose the special meaning that was assigned to them by Husserl and Heidegger.
On a practical note, it is important to consider the possible difficulties of participants expressing themselves.
Participants need to be interested and articulate - problems that can cause difficulties in being able to express themselves include foreign language, age, brain damage, and embarrassment.
