Problem 4: Nisbett and Wilson Findings
Freud claims that patients' veridical insight causes a durable cure of psychoneurosis. Thus, the epistemic reliability of patients' intropections is of utmost importance. However, cognitive psychologists Nisbett and Wilson (1977) have shown that just like outside observers, subjects have only inferential, rather than privileged, access to the causal linkages that actually connect their mental states.
The figure below (Von Eckardt, 1986) represents epistemological problems in Freud's use of clinical data as discussed by Grünbaum (1984) (circled numbers correspond to numbered problems at left; arrows represent the relation "is considered evidence for").
- suggestibility (pp. 130-135);
- failure of tally argument (pp. 135-172);
- weakness of consilience argument (pp. 273-278);
- Nisbett and Wilson findings (pp. 147-148);
- problems with Breuer-Freud argument (pp. 177-189);
- problems with extrapolation to slips and dreams (pp. 190-239);
- problems with establishing causal claims by retrospective testing (pp. 177-189).
