While I agree that "absolutely" is an overstatement, there really is some validity to gender-specific critical thinking.
Lawyers use those "profiles" all the time in jury selection.
"Scientific" jury selection is a pseudo-science. There is no clear evidence to support it's efficacy.
From
http://en.wikipedia.org/wiki/Scientific_jury_selection:
Although advocates and practitioners of scientific jury selection claim the practice is overwhelmingly effective at choosing juries that will render the desired verdict, its true effect is often more difficult to discern. Part of this difficulty is in duplicating the conditions of a real trial. In one experiment, two kinds of shadow juries watched a trial and rendered a verdict. The results indicated that the juries were substantially different, but that this difference was likely due to the two experimental juries’ knowledge that they were not deciding an actual verdict, prompting a lower burden of proof.[19]
Another simplified experiment indicated that lawyers trained in a systematic selection method made better predictions of juror verdicts in two of four cases – the sale of illegal drugs and a military court-martial (the other two cases were murder and drunk driving). The systematic method was more effective in those two cases where the predictive relationships between demographic variables and attitudes/verdicts were strongest, and least effective where such predictive relationships were weak or nonexistent.[20]
Some academic researchers argue that the actual efficacy of SJS is obscured by poor research methodology. Specifically, demographic characteristics used to predict juror attitudes and juror verdicts may not hold true across all kinds of cases. For example, men convict more frequently than women in some types of criminal trials but less frequently in others.[21] Besides this, demographic characteristics are often less predictive than the attitudes jurors hold; for example attitudes towards rape are better verdict-predictors than gender in rape trials.[22]
The actual efficacy of jury consultants may not be very important because the demographic composition of the jury has little effect on the verdict it renders, usually causing only a 5%–15% variance in verdicts.[23][24] The evidence presented at trial has far more impact on what the verdict will be.[25] As Kressel and Kressel indicate, "when the evidence is strong, nothing else matters much" and even when the evidence is ambiguous, demographic characteristics of jurors are a relatively minor influence.[26] Some researchers argue that a significant improvement in jury selection, however small, may be worthwhile when the stakes are high, like for a defendant accused of a capital crime or a corporation that stands to lose millions of dollars in a civil suit.[23]
A key issue in the efficacy of scientific jury selection is the fact that the overwhelming majority of attempted efficacy research employed models of practice only used by what might best be termed "unqualified" or inadequately trained practitioners. These groups may indeed focus on using outdated demographics, but fully qualified litigation psychologists do not. This brings up a second issue that efficacy research has neglected to address: namely, the wide variability in practitioner quality, training, education, and professional preparation. To date, no efficacy study has properly accounted for the fact that many jury consultants, perhaps even a majority, are simply unqualified to design scientific research, craft scales to accurately and reliably measure juror psychographics, and conduct the sophisticated statistical modeling and analysis employed by properly qualified Litigation Psychologists.
