    sales ability testing -- does it work? Best answer on the web
    Filed under: tarareidtopless.com
  • One of the challenges faced by many businesses (mine included) is finding talented salespeople. A number of commercial organizations offer sales/personality tests, and of course all claim that theirs work 'best'. My searches on the web on this topic of course have turned up only the commercial self-serving claims. Are there independent, academically sound and well researched studies on this topic, and if so, I welcome abstracts and rankings/recommendations.


  • Maybe not exacly the answer I wanted -- but a valid answer nonetheless (and sometimes the results you don't get can be as useful as the ones you do.)


  • Hello again,

    I'm very confident of the academic quality of the citations/abstracts I provided. By limiting my google searches to "edu" sites I was able to avoid the self-serving commercial misinformation found on "com" sites. The last four abstracts I provided were located in an online database that indexes academic publications focusing on business/economic/marketing research. If you want only peer reviewed academic articles you're in a a jam. There doesn't appear to be much out there. Two that are peer reviewed are included here:

    Have your librarian run some searches for you to verify the cites. The search keywords I used were ""sales personnel AND ability testing"
    Thanks again.

  • Hello Marbuck,
    I searched on a couple of databases for papers published in peer-reviewed academic journals, and found the following which may be of interest to you. It appears that there is certainly evidence that some types of testing do work. This does not mean that all (or any one specific measure) does work.
    If there are specific measures that you are interested in (or people have tried to sell to you :) ), you might want to ask a new question, and search for information.

    SO PSYCHOLOGICAL REPORTS
    AB The hypothesis of a relationship between Machiavellian behavior
    and sales performance of Christie and Geis was tested with a
    sample of 110 stockbrokers. Scores on a measure called the
    Machiavellian Behavior scale were positively and significantly
    correlated with two self. reported measures of sales
    performance of the stockbrokers, Present results together with
    those of two earlier studies supported the hypothesis that
    salespeople with a Machiavellian orientation are likely to be
    more successful, Analysis of the data also indicated predictive
    validity and acceptable internal consistency of the
    Machiavellian Behavior scale, Limitations of the present study
    and a need for further research are discussed.

    TI Personality and job performance: Test of the mediating effects
    of motivation among sales representatives
    SO JOURNAL OF APPLIED PSYCHOLOGY
    AB Research shows consistent relations between personality and job
    performance. In this study the authors develop and test a model
    of job performance that examines the mediating effects of
    cognitive-motivational work orientations on the relationships
    between personality traits and performance in a sales job (N =
    164). Covariance structural analyses revealed proximal
    motivational variables to be influential mechanisms through
    which distal personality traits affect job performance.
    Specifically, striving for status and accomplishment mediate
    the effects of Extraversion and Conscientiousness on ratings of
    sales performance. Although Agreeableness was related to
    striving for communion, neither Agreeableness nor communion
    striving was related to success in this sales job. The
    importance of the proposed motivational orientations model is
    discussed.

    AB This study examined the relationship between ear preference,
    personality, and performance ratings on 203 telesales staff.
    Social desirability scores were a significant predictor of two
    relatively independent sets of supervisor ratings (actual
    performance and developmental potential) in interaction with
    ear preference. It was found that the social desirability scale
    was a significant positive predictor for staff preferring a
    right ear headset, but a negative predictor for staff
    preferring a left ear headset. These results were interpreted
    in terms of different strategies used to achieve successful
    sales.

    TI Narcissism and achievement motivation as related to three

    SO JOURNAL OF BUSINESS AND PSYCHOLOGY
    AB Relationships were posited between two personality constructs-
    narcissism and achievement motivation--and three facets of the
    sales role: attraction, satisfaction and performance. As
    predicted, currently and previously employed salespeople were
    more narcissistic and had stronger needs for achievement than
    individuals who were never employed in sales. Narcissism was
    positively associated with overall sales satisfaction and with
    level of comfort with ethically questionable sales behaviors;
    narcissism was unrelated to sales performance. In contrast,
    need for achievement was unrelated to sales satisfaction,
    negatively related to comfort with ethically questionable sales
    behaviors, but positively related to sales performance.
    Practical implications of these findings for sales recruiters
    and trainers are discussed.

    TI The joint relationship of conscientiousness and ability with
    performance: Test of the interaction hypothesis
    SO JOURNAL OF MANAGEMENT
    AB This study investigated whether conscientiousness and ability
    interact in the prediction of job performance, Although few
    studies have directly addressed this issue, there is limited
    evidence that ability moderates the relationship between
    conscientiousness and job performance. Specifically, it has
    been reported that the relationship of conscientiousness to
    performance is positive for high ability and near zero or
    negative for low ability. Results in the present study provided
    no support for the interaction of GMA and conscientiousness,
    Moderated hierarchical regression analyses for three
    independent samples of participants (146 managers in sample 1,
    103 sales representatives in sample 2, and 121 managers in
    sample 3), showed that the interaction did not account for
    unique variance in the prediction of supervisory ratings of job
    performance beyond that accounted for by GMA and
    conscientiousness. These findings indicate that ability does
    not moderate the relationship of conscientiousness to job
    performance. Practical implications for employee selection
    practices, and theoretical implications for models of job
    performance, are discussed. (C) 1999 Elsevier Science Inc. All

    SO PERSONALITY AND INDIVIDUAL DIFFERENCES
    AB Just over two hundred telephone sales staff completed the
    Eysenck Personality Inventory (EPI) and Honey and Mumford's
    Learning Styles Questionnaire (LSQ). Extraversion was highly
    correlated both positively and negatively with three of the
    four LSQ measures. The lie scale from the EPI was also
    systematically correlated with the Activist and Reflector
    scales of the LSQ. Both the EPI and LSQ traits were modestly
    correlated with two criteria: ratings of Actual Performance and
    Development Potential. Regressions were used to determine the
    best predictors of the two ratings measures. Personality
    variables (extraversion, neuroticism) and certain learning
    styles (reflector, pragmatist) were statistically significant
    predictors of rated performance, though they accounted for less
    than 10% of the explained variance. The results concur with
    recent meta-analytical studies that show personality variables
    account for a small but important amount of variance in
    measures of work performance. > (C) 1999 Elsevier Science Ltd.

    TI Specification of scales in biodata form development: Rational
    vs. empirical and global vs. specific
    SO INTERNATIONAL JOURNAL OF SELECTION AND ASSESSMENT
    AB Although empirical keying has been the most popular scoring
    strategy with biodata, researchers have increasingly argued
    that rational approaches are better for advancing theory.
    Higher validities and less faking with empirical keys, however,
    have made many reluctant to abandon them. Research in the
    personality field provided support for the notion that many
    rational biodata scales may be multi-faceted. Development of
    more specific scales was suggested as a technique for creating
    rational scales with validities that more closely approximate
    that of empirical keys. Three different strategies (rational,
    internal, and external/ empirical) were used in the scoring of
    a biodata inventory for use with mechanical equipment franchise
    owners. The rational and internal approaches were investigated
    within two samples and at two levels - very specific constructs
    and global constructs. In addition, two types of criteria were
    used, including an objective measure of sales and supervisory
    performance ratings. The specific rational scales were as
    predictive as the empirical item key. Strategies for developing
    and scoring a biodata form using a rational approach are
    discussed.

    TI The influence of goal orientation and self-regulation tactics

    SO JOURNAL OF APPLIED PSYCHOLOGY
    AB The authors investigated the influence of goal orientation on
    sales performance in a longitudinal field study with
    salespeople. As hypothesized, a learning goal orientation had a
    positive relationship with sales performance. This relationship
    was fully mediated by 3 self-regulation tactics: goal setting,
    effort, and planning. In contrast, a performance goal
    orientation was unrelated to sales performance. These results
    suggest that a focus on skill development, even for a veteran
    workforce, is likely to be associated with higher performance.
    Management should seek evidence of a learning goal orientation
    when selecting new employees, while avoiding an excessive focus
    on performance goal orientation without a comparable skill-
    development focus.

    AB This meta-analysis evaluated predictors of both objective and

    ability inventories were good predictors of the ratings
    criterion, with corrected rs of .52 and .45, respectively.
    Potency (a subdimension of the Big 5 personality dimension
    Extraversion) predicted supervisor ratings of performance (r
    =.28) and objective measures of sales (r =.26). Achievement (a
    component of the Conscientiousness dimension) predicted ratings
    (r =.25) and objective sales (r=.41). General cognitive ability
    showed a correlation of .40 with ratings but only .04 with
    objective sales. Similarly, age predicted ratings (r =.26) but
    not objective sales (r = -.06). On the basis of a small number
    of studies, interest appears to be a promising predictor of
    sales success.

    TI Personality-performance correlations at work: Individual and
    aggregate levels of analyses
    SO PERSONALITY AND INDIVIDUAL DIFFERENCES
    AB In the occupational community, there is a widespread faith in
    the utility of personality assessment for selection,
    development, etc. This faith has been immune to arguments,
    supported by empirical evidence, regarding the poor correlation
    between personality and performance in the workplace (these
    correlations rarely exceed the 0.2-0.3 level). The difference
    between perception of utility and the actual empirical reality
    is large. We investigated one possible source of this
    perceived-actual discrepancy. In two separate samples, we
    compared the magnitude of validity coefficients from individual
    and aggregate (i.e. organizational) levels. Our results
    indicated that strong actual personality-performance
    correlations exist at the aggregate level of analysis, but not
    at the individual level of analysis. We suggest that this
    aggregate-individual correlation discrepancy may, in part at
    least, account for the perceived-actual discrepancy noted
    above. We conclude that the continued faith in personality
    testing in the workplace may be a consequence of test users'
    sensitivity to actual aggregate level personality-performance
    correlations. However, we warn of the danger of drawing
    inferences from aggregate level correlations when making
    decisions about individuals, and point out the statistical
    artefacts that may account for some of the magnitude increase
    in aggregate level correlations. Several foci for further
    research are indicated. (C) 1998 Elsevier Science Ltd. All

  • This may be telling me something interesting -- if so little real academic research has been done on the topic, then I fear that most of the sales testing stuff on the market may indeed be 'hocus pocus'. Some of the abstracts you gave me appear to be, for want of a better word, 'planted' stories (ie a commercial concern writes up something in the form of an academic paper, and submits it to a possibly low-standards journal -- to give it 'credibility' in its own marketing materials.
    We are of course not looking for retail salespeople as for example an hourly rated store employee. This is Business to Business stuff. Would your research be able to classify the 'status' and credibility of the journals cited -- I am ready to ask a librarian to pull copies of journal articles, but would hate wasting money/research time on academic junk.
