"Any meaningful discrepancy based on the complete data is clearly attributable not to gender but to seniority of the employee.
W.W.'s scores on the same stimuli (anger 9/10; fear 8/10; happiness, 8/10; sadness, 9/10) indicate that B.R.'s performance profile was not attributable simply to stimulus factors.

Although auditory spatial performance correlated with patients' working memory capacity in both verbal and non-verbal domains, the auditory spatial deficits demonstrated were not attributable simply to this factor.
Thus, there is no evidence that observed differences are due to late presentation or inequalities in the receipt of therapy and, therefore, breast cancers arising in young black women appear to be biologically different; an effect not attributable simply to the young age of affected individuals.
To ensure that the observed binding of pluripotency factors to rDNA was not simply attributable to the highly accessible chromatin architecture and high number of active rDNA repeats, we first analyzed ChIP-seq data for nuclear GFP (nGFP) (Yamaji et al. 2013), because GFP has been shown to give artifactual ChIP signals at highly expressed loci (Teytelman et al. 2013).
We are confident that the lack of consistency in the effect of attending to motion is not simply attributable to the motion localizer being somehow 'inappropriate' for some individuals.

Thus, the effect was not simply attributable to an alteration in response bias but appeared to be a genuine decrement in sensitivity.
