The Barnum effect in a computerized Rorschach interpretation system

Twelve psychiatric outpatients were administered the Rorschach test, and results were interpreted using the Exner (1983, 1986) Report for the Comprehensive System computer-based test interpretation (CBTI) program. Four psychiatrists made accuracy ratings for both real and bogus reports for each of their patients. Data were analyzed using two-way analyses of covariance (ANCOVAs), where report type was a repeated main effect, psychiatrist was a random main effect, and the number of statements in the report was the covariate. Results indicated that this CBTI provided only 5% discriminating power for any one patient, with 60% of the interpretive statements merely describing typical characteristics of the outpatient population. No significant psychiatrist, interaction, or covariate effects were encountered.     

How leaders really emerge

Comments on the article by R. J. Hackman and R. Wageman which offered several research questions that should be productive for furthering leadership research. This comment summarizes some recent progress on one of those questions, "Not what are the traits of leaders, but how do leaders' personal attributes interact with situational properties to shape outcomes?"     

The relation between the locus of control construct and involvement in traffic accidents

We investigated the relation between the Rotter (1966) locus of control concept and involvement in automobile accidents. Subjects were 184 college students who completed a survey measuring accident involvement, the Rotter scale, and scales featuring beliefs and behaviors in traffic situations that would be expected from internally oriented persons. No significant relation was found between the Rotter scale and traffic accidents. Accident involvement was best explained by internal beliefs about accident control, and the reported number of near-miss accidents per week. A path diagram relating survey variables is included.     

Making choices in anticipation of similar future choices can increase self-control

Two experiments tested the efficacy of linking a current choice with similar future choices as a means of increasing self-control. Participants were offered choices between smaller and sooner vs. larger and later amounts of money (Experiment 1, n = 60) or food (Experiment 2, n = 34). After a small-large pair for which the participant preferred the smaller reward was found, a choice between the same pair was offered as the 1st of 5 such choices to be offered over a period of weeks. The majority of participants in both experiments who chose between all 5 smaller and all 5 larger rewards chose the larger rewards. One third of participants in Experiment 1 who could choose independently on each pair in the series reversed their previous preference and chose the larger reward in the context of the series. These results suggest that self-control can be enhanced by viewing one's current choice as predictive of future choices.

Assessment of the Barnum Effect in Computer-Based Test Interpretations

A prototypic experiment for validating computer-based test interpretations (CBTIs) was conducted. Undergraduates (N = 63) completed the Comprehensive Personality Profile Compatibility Questionnaire (CPPCQ; Craft, 1987). One treatment group rated real CBTIs for relative accuracy, and another group rated bogus CBTIs. A significant main effect for differences in ratings indicated that the real CPPCQ profiles were rated as 74.5% accurate whereas the bogus CBTIs were rated as 57.9% accurate. Several covariate effects were tested, but none were significant.     

A review and critique of honesty test research

This paper reviews and critiques research pertaining to the three most commonly used honesty tests. Honesty tests, sometimes called integrity tests, purportedly predict theft by employees. Secondary analyses were performed to remove the effect of faking good from validity coefficients with various self-report criteria, and to supplement other analyses. The honesty tests were found to have: (a) virtually no foundation in personality or attitude theory, (b) a corrected average correlation of 0.08 with objective indices of theft (95′/0 confidence interval: 0.03 < r < 0.14), (c) a Taylor-Russell utility of approximately 1% above base rate of success, and (d) a false positive rate of 0.44 if only nontrivial thefts are considered. The honesty tests reviewed are of such marginal validity (less than 1% of the criterion variance accounted for) that their continued use in preemployment settings is seriously questioned. The comparability of these review results with those of other reviewers is discussed along with the social and legal implications of honesty testing.     

Androgyny,Gender Role Behavior,and Emotional Intelligence Among College Students and Their Parents

Androgyny, gender role behavior, and emotional intelligence were measured in 576 students and their parents to examine the extent to which these variables exhibited generational effects or consistencies within families. Chi-square analyses indicated that sons were more androgynous in personality than their fathers, but that there was no significant difference in androgyny between daughters and mothers. The men also showed an increase in androgynous behavior across generations, whereas the women showed an increase in masculine gender-typed behavior and a decrease in feminine gender-typed behavior. ANOVA revealed that fathers scored significantly lower on emotional intelligence than mothers and students. Significant correlations on emotional intelligence for mothers and their respective students indicated a strong influence on this construct; no such relationship was found between students and fathers. The strongest correlations in masculine and feminine personality and behavior were obtained for mothers and daughters. It was also hypothesized that androgyny would predict higher emotional intelligence; multiple regression supported this hypothesis for students, mothers, and fathers.
