The psychodynamic approach lacks scientific support because Freud's ideas were based on his own experiences with patients rather than systematic observation or experimentation.
Freud did not conduct experiments to test the validity of his theories, which means that they cannot be tested through controlled studies.
Psychodynamic theory is not supported by research as it has been criticised for being unscientific, lacking empirical evidence.
Little hans
case study= idiographic= not generalisable
results may be biased cos info came from hans' father
no cause and effect can be established
it is psychically reductionist
lots of freud's research only focused on males- beta bias
socially sensitive- says female homosexuality was due to an absent father
based on subjective interpretations so theyre biased and unreliable
unfalsifiable due to focus on unconscious mind
psychoanalysis is expensive and time consuming and also may cause pts distress
