Which psychologists are most likely to criticize standardized personality tests for failing to capture the unique subjective experience of the individual personality?

Humanistic.

Explanation:

In psychology, the humanistic approach was born as an alternative to the behaviorist and psychodynamic approaches.

Humanistic psychologists reject the deterministic assumptions often made in the behaviorist and psychodynamic perspectives. According to humanistic psychologists, both of these other approaches dehumanize human beings and see them as people who are determined by external forces rather than people with all the inner abilities and capacities to cope with life.

Humanism states that people are basically good, and have an innate need to make themselves and the world better, they also have an inner tendency to self-actualization. This approach also thinks that the subjective  experiences of the individual are really important, therefore they study personality and personal experiences from the point of view of the individual's own subjective experience.  

Thus, the psychologists that are most likely to criticize standardized personality tests for failing to capture the unique subjective experience of the individual personality would be the humanistic psychologists.
