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.

Keywords

💡Bias

Bias refers to a systematic error or deviation from accuracy or fairness in judgment. In the context of the video, bias is a significant issue in recruitment and selection processes, as it can lead to the hiring of candidates based on personal preferences rather than their qualifications. The video discusses various types of biases that can affect selection methods, such as affinity bias and confirmation bias, and emphasizes the importance of recognizing and overcoming these biases to ensure fair and effective hiring practices.

💡Affinity Bias

Affinity bias is the tendency to prefer people who are similar to oneself or remind us of someone we like. In the video, it is mentioned as a type of bias that can influence the selection process, where interviewers might favor candidates they feel an affinity for, potentially overlooking more qualified candidates who do not share the same characteristics or background.

💡Confirmation Bias

Confirmation bias is the inclination to search for, interpret, favor, or recall information in a way that confirms one's preexisting beliefs or hypotheses. The video uses the example of reviewing a CV with a preconceived notion about a candidate and then seeking information that confirms this initial impression, which can skew the selection process away from an objective evaluation of the candidate's qualifications.

💡Social Desirability Bias

Social desirability bias is the tendency to respond in a manner that is perceived as socially acceptable or desirable rather than providing a truthful response. The video suggests that this bias can affect interviewees, who might give answers they believe the interviewer wants to hear, especially when faced with ethical dilemmas, rather than their genuine opinions or feelings.

💡Out-group Homogeneity

Out-group homogeneity is the perception that members of a different group, based on factors like gender, ethnicity, or social class, are all similar and can be generalized. In the video, it is discussed as a bias that can lead to the assumption that individuals from different groups behave in a uniform way, which may result in not interviewing or considering diverse candidates.

💡Status Quo Bias

Status quo bias is the preference for maintaining the current state of affairs. The video describes this bias as the inclination to hire candidates similar to those already in the organization, as it feels less risky and predictable. However, this can lead to groupthink, where diverse ideas and opinions are not considered, potentially hindering organizational growth and innovation.

💡Self-serving Bias

Self-serving bias is the tendency to attribute positive outcomes to one's own abilities and negative outcomes to external factors. In the context of the video, this bias can manifest after a hiring decision has been made, where the interviewer may justify their choice in a way that makes the new hire appear better than they might be, often ignoring or rationalizing away any contradictory evidence.

💡Validity

Validity in the context of the video refers to the accuracy and reliability of the selection methods used in the hiring process. The video suggests that while various instruments like structured interviews and tests have high validity, they are not infallible and should be used in combination to mitigate the impact of biases and ensure a more comprehensive and fair selection process.

💡Groupthink

Groupthink is a phenomenon where a group makes decisions based on the desire for harmony and conformity rather than critical evaluation of alternative ideas. The video warns that status quo bias can lead to groupthink within an organization, where hiring similar types of people can stifle diversity of thought and potentially harm the organization in the long term.

💡Selection Methods

Selection methods are the various techniques and tools used to assess and choose candidates for a job. The video discusses the importance of using multiple selection methods, such as structured interviews, tests, tryouts, reference checks, and job knowledge tests, to increase the validity of the selection process and reduce the influence of biases.

💡Organizational Culture and Strategy

Organizational culture refers to the shared values, beliefs, and behaviors that characterize an organization, while organizational strategy outlines the long-term goals and actions of the organization. The video emphasizes the importance of selecting candidates who not only have the necessary skills for the job but also align with the company's culture and strategy to ensure a good fit and contribute positively to the organization.

[Music]

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
