Q & A
What is the main topic of the video script?
-The main topic of the video script is the discussion of biases in recruitment and selection processes and how to overcome them.
What is Affinity bias?
-Affinity bias is the tendency to like people who are similar to us or remind us of someone we like, which may lead to selecting candidates based on personal affinity rather than their qualifications.
Can you explain Confirmation bias in the context of recruitment?
-Confirmation bias in recruitment is the tendency to search for or interpret information that confirms one's preconceptions about a candidate, often leading to overlooking other important aspects of their profile.
What is Social desirability bias and how might it affect an interviewee's responses?
-Social desirability bias is the tendency to give responses that are perceived as socially acceptable rather than responses that accurately reflect one's true feelings or beliefs, which may affect an interviewee's answers to ethical dilemmas or personal questions.
What is Out-group homogeneity bias and how does it relate to recruitment?
-Out-group homogeneity bias is the perception that everyone who is different from us and belongs to a different group (based on gender, ethnicity, social class, etc.) is similar and behaves in a particular way, which may lead to not interviewing or stereotyping candidates based on their group affiliation.
What is Status quo bias and how can it impact hiring decisions?
-Status quo bias is the preference for maintaining the current state of affairs, which in hiring can lead to choosing candidates similar to those already hired, potentially causing a lack of diversity and groupthink within an organization.
What is Self-serving bias and how does it manifest in the hiring process?
-Self-serving bias is the tendency to justify one's decisions in a way that makes the choice appear better than it might be, which in hiring can lead to post-hoc rationalization and ignoring test findings that do not fit the initial positive view of the candidate.
Why is it important to use multiple selection methods in recruitment?
-Using multiple selection methods increases the validity of the process and helps to mitigate the effects of biases, ensuring a more comprehensive evaluation of candidates based on their fit with the organizational culture, strategy, job requirements, and team dynamics.
What types of selection instruments are suggested to have high validity in the script?
-The script suggests that structured job interviews, tests, job tryouts, reference checks, and job knowledge tests have high validity as selection instruments.
How can an organization ensure that biases are minimized during the selection process?
-An organization can minimize biases by being aware of common biases, using multiple selection methods, focusing on both technical skills and behavioral skills, and ensuring that the selection process aligns with the organizational culture and strategy.
What is the final recommendation made in the video script regarding the selection process?
-The final recommendation is to use multiple different selection methods that focus on technical skills, behavioral skills, and personality attributes to find a candidate who fits well with the organization's culture, strategy, job requirements, work group, and possibly the supervisor.
Outlines
🔍 Overcoming Biases in Recruitment and Selection
This paragraph discusses the prevalence of biases in recruitment and selection processes. It introduces several types of biases such as Affinity bias, which is the inclination to favor candidates similar to us, and Confirmation bias, where individuals seek information that aligns with their preconceived notions. Social desirability bias is also highlighted, where interviewees might provide answers they believe are socially acceptable rather than their true thoughts. The paragraph also touches on Out-group homogeneity, Status quo bias, and Self-serving bias, explaining how each can skew the selection process. The importance of using valid selection instruments is emphasized, and research suggests that a combination of structured job interviews, tests, reference checks, and job knowledge tests can help mitigate biases and improve the selection process.
📚 Strategies for Effective and Bias-Free Selection
The second paragraph emphasizes the importance of using multiple selection methods to increase the validity of the hiring process and reduce the impact of biases. It reiterates the types of biases that can affect selection methods, such as Affinity and Confirmation biases, and stresses that no single method is sufficient on its own. The paragraph concludes by advocating for a comprehensive approach that considers technical skills, behavioral skills, and personality attributes to ensure the selected candidate is a good fit for the organization's culture, strategy, job requirements, work group, and team dynamics.

we have discussed selection methods we
have discussed recruitment
now it is important to understand that
Recruitment and selection can often be
biased
how do I overcome these biases well the
first step is to understand what are
these biases understand some of them
now first bias that I'm going to be
introducing you to is called the
Affinity bias that is the tendency to
like people who are similar to us or who
remind us of someone we like
this may lead to selecting candidates
who we have an affinity for
rather than the best candidate
the second is a confirmation bias which
is the tendency to search for
or interpret information that confirms
one's preconceptions
for example some people may have looked
at a CV and have a preconceived notion
about this candidate
then they will search for information or
interpret information that they are
saying
that will confirm what they had
previously thought about
social desirability bias the tendency to
give a perceived socially desirable
response to a question instead of a
response that is accurately
reflects you as an individual
this might be a bias that interviewee is
faced so when you ask them for a
question which has an ethical dilemma in
it they might be giving you a socially
desirable answer then an answer that
they actually like or feel like
we have already spoken about this but
just to reintroduce it out group
homogeneity
the perception that everyone who is
different from me and belongs to a
different group that could be based on
things like gender ethnicity social
class Etc is similar I don't need to
interview them or I already know that
they behave in a particular way
status quo bias is often also seen that
is it feels less risky to hire someone
that is similar to the people you have
already hired
you feel
you know what to what you get so it's
better however if you look at it from an
organization's point of view often that
may lead to what we call group think
where diverse ideas are not being
discussed diverse opinions are not being
introduced which may have a long-term
negative effect on your organization you
may also be involved in self-serving
bias that is once you have chosen
someone you try to justify that choice
in such a way that the new hire will
look better
this can lead to a lot of things for
example post-hoc rationalization
example of this would be
explaining away or ignoring tests
findings that were there but they don't
fit in with your view so the validity of
these instruments that we use for
selection becomes important because
biases can be introduced in any of them
so what does research suggest research
first suggests that instruments such as
structure job interviews tests job
tryouts reference checks job knowledge
tests have all validity they have high
validity but by themselves they do not
have enough validity to be considered as
a silver bullet to all our problems
therefore it makes most sense to use
multiple methods when you are selecting
somebody
while keeping an attention on the kinds
of biases that might be introduced in
different selection methods
it is also important to understand that
when you are selecting somebody you are
trying to fit
them with the organizational culture and
organizational strategy
you're also trying to fit them with the
job that you have you're also trying to
find out whether they fit with the work
group or the sub work group or the team
that you have and therefore using
multiple different methods that Focus
both on technical skills behavioral
skills and personality attributes
will be most valid and most beneficial
for you as an organization
to quickly summarize this video
in this video I introduced you to
different biases such as Affinity bias
confirmation bias social desirability
bias Etc that may creep into selection
methods
by themselves selection methods each of
the selection method has some validity
but not enough to hold its own weight
and therefore it is most
ideal that you use multiple different
selection methods
when you are doing selection
this will not only increase validity but
will also ensure that your biases are
lower so and you find a person who fits
not only with the culture and strategy
of your organization but also fits with
the job
with the work group or with the team
and possibly with also the supervisor
thank you and I shall see you in the
next video
