Merckelbach, H., & Collaris, J. (2012). Mother Teresa Doesn't Help Here: Lack of Moral Priming Effects on Malingered Symptom Reports and What We Can Learn from it. Psychologica Belgica, 52(2-3), 2-3.

The issue of how to reduce malingered symptom reports is an important one.
We explored whether exposing people to a moral prime would reduce their tendency
to engage in malingering. Using an instructed malingering paradigm (N
= 90), half of the participants were given the option to malinger symptoms,
whereas the other half was asked to respond honestly. Within each group, some
participants received no further instructions; others were warned that malingering
might be detected, while still others were given a prime that consisted of
questions about moral topics
(i.e., the Mother Teresa Questionnaire). Next, a
symptoms scale, and two dedicated malinger tests were administered. Malinger
instructions generated heightened scores on the symptoms scale, and deviant
performance on the malinger instruments. Moral priming, however, did not
reduce malingering tendencies. We present follow-up data from a clinical context,
which suggest that it might be worth pursuing moral prime effects on
malingering outside the lab.
