The concept of gaining insights into clients by means of tools and diagnostic procedures rests on the notion that certain information and its completeness is necessary to arrive at a measured diagnosis. The notion is scientifically verified and tested.
Therefore, there are many instruments for the recording of defined conditions: suitability for a role, psychological impairment, i.e. burnout, narcissism, or behavioural structures or prevalences (MBTI, DISG/DISC). To a certain extent, these instruments ostensibly replace the perception of the counsellor (ultrasound instead the physician’s touch). Nevertheless, in turn, a counsellor is required in order to interpret the results of the tool/test etc.
The danger consists of thinking that a tool will give, in itself, a valid and objective result, which does not have to be further interpreted for its meaningfulness and significance.
