Traditionally, employee selection tests focus on cognitive abilities such as reading, reasoning, and math.  These have large Black-White (B-W) effect sizes (standardized mean score differences).  The range of other abilities that have been tried may be too narrow.  This note is part of an effort to identify abilities that might plausibly be related to job performance and might have small B-W effect sizes but that linkage is not the topic of this question.As pointed out in a comment, this topic is quite broad.  I do not expect a direct answer. Rather I am hoping to get citations to recent published literature with information to answer this question:  What abilities (or ability sub-areas) show little or no B-W mean score differences?  For example, are there effect size estimates (and available measures) for: creativity, facial recognition (as in choosing a face out of a crowd), memory for faces, voice quality (as in command presence for a police officer), cooperativeness, fairness, calmness under pressure, warmth, etc.  (The jobs I have in mind right now are Police Officer and Firefighter.) Note: This question has a different focus than this related question: Reducing adverse impact, discrimination and unfairness when using psychological assessments for selection purposesAddendum:In response to comments, let me clarify the reason for this broad question.  Industrial psychologists tend to use a narrow range of cognitive ability areas when developing employee selection procedures, and the abilities considered typically are those that were known to the field in the mid 1900's, or before.  Perhaps that is part of the reason that the best employee selection tests explain, at most, 25% of the variance in job performance.  Beyond that, most employee selection procedures are supported by content validation evidence, not criterion related.  Subject matter experts (SMEs) may be incapable of articulating entry-level cognitive abilities (i.e., not job knowledge) in other than the broadest ways.  Typically, SMEs rate the ability areas provided to them in a questionnaire.  If an ability is not included in the questionnaire, it is not rated and not considered for inclusion in the selection procedure.  I am wondering if there are other cognitive ability areas that I might review to see if they are related to job performance, particularly abilities that show little or no B-W differences in mean scores.  I am reaching out beyond my area of specialty.  I hope to find review articles that summarize the information I seek.
What cognitive abilities show the smallest B-W differences in mean scores?
