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) 2. What is the meaning of the statement “different
ethnic groups obtain significantly different mean ability test
scores”? (3) 3. What possible differences should be taken into
account during an interpretation of psychometric data in South
Africa? (4)
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?
Yes, I agree with the statement.
Reasoning:
Psychometric testing can be interpreted as falling under the
definition of an unfair labour practice if it results in
discriminatory outcomes that disproportionately affect certain
ethnic groups. In South Africa, where there is a history of ethnic
and racial discrimination, psychometric tests might not be
uniformly valid across different ethnic groups. If these tests
result in significant disparities in mean ability scores among
different ethnic groups, and if these differences are not
adequately addressed or justified, it can lead to unfair practices.
For instance, if a test is biased in a way that consistently
disadvantages a particular ethnic group, using the results of such
tests to make employment decisions could perpetuate existing
inequalities and reinforce discriminatory practices. Therefore,
ensuring that psychometric tests are fair and equitable for all
