CASE STUDY
READ CAREFULLY FROM THE FOLLOWING THE ABSTRACT FROM THE
ARTICLE PUBLISHED in the South African Journal of Psychology.
The concept of unfair labour practice has been introduced into South Africa through the
Labour Relations Act and it is argued that certain psychometric testing practices can
be interpreted as falling under the definition of an unfair labour practice. Empirical
results are presented indicating that different ethnic groups obtain significantly different
mean ability test scores. A case study is cited to show that this would result in an
underprediction of performance on a criterion for the lower scoring of two groups if test
scores are regarded as comparable. It is argued that any interpretation of psychometric
data in South Africa that does not take into account of possible differences between
ethnic groups is likely to ignore a significant moderator variable, given the history of
ethnically based discriminatory practices in this country. Arguments based on meta-
analytical research in the USA, to the effect that psychometric ability tests do not
discriminate unfairly against disadvantaged groups if the same tests and norms are
used, should not be assumed to hold in South Africa. Various conceptions of what
constitutes fairness in selection are considered, and it is concluded that there is a need
for employers to make explicit in their selection policies the trade-off between economic
and social costs of employment practices. Finally, some implications for users of
psychometric tests in industry are considered, to forewarn of likely developments in this
field.
1. Do you agree with the statement that “certain psychometric testing practices
can be interpreted as falling under the definition of an unfair labour practice”,
and why? (3)
Yes, I agree with the statement that certain psychometric testing practices can be
interpreted as falling under the definition of an unfair labor practice. This is because, as
the abstract indicates, empirical results show significant differences in mean ability test
scores among different ethnic groups in South Africa.
, These differences suggest that psychometric tests may not be equally valid for all
groups, potentially leading to biased and unfair outcomes in employment selection
processes. Moreover, if test scores are regarded as comparable across different
groups without accounting for historical and contextual factors, there is a risk of
underpredicting performance for lower-scoring groups, thus perpetuating inequality (SA
Journal of Industrial Psychology, 2007, 33 (1), 102-117)
The history of ethnically based discriminatory practices in South Africa further supports
the need for a cautious interpretation of psychometric data. Arguments that
psychometric ability tests do not discriminate unfairly in other contexts, such as the
USA, cannot be assumed to hold in South Africa due to the unique socio-historical
background (South African Journal of Psychology, n.d.). Thus, employers should be
aware of these differences and consider the fairness of their selection policies to avoid
unfair labor practices.
2. What is the meaning of the statement “different ethnic groups obtain
significantly different mean ability test scores”?
The statement "different ethnic groups obtain significantly different mean ability test
scores" means that when psychometric ability tests are administered, the average
scores (mean scores) differ notably among various ethnic groups. This indicates that
individuals from certain ethnic groups tend to score higher or lower on these tests
compared to individuals from other groups.
The differences in scores could result from several factors, including cultural bias in the
test design, socio-economic disparities, differences in access to quality education, and
other environmental factors. In the South African context, these differences might also
reflect the lingering effects of historical inequalities and discrimination that have
impacted access to resources and opportunities. Such disparities suggest that the tests
may not equally or fairly assess the true abilities of individuals from different
backgrounds, raising concerns about the validity and fairness of using these tests for
employment selection or other purposes.
