Q & A
What are the Whistler scales and how do they differ from the Stanford Benet?
-The Whistler scales are a set of intelligence tests created by Wisher, which include separate tests for different age groups: children, adults, and preschool/primary. Unlike the Stanford Benet, which didn't account for age beyond the formula, the Whistler scales were designed to be more age-appropriate.
What was the main issue with the original Stanford Benet that led to the creation of the Whistler scales?
-The main issue with the original Stanford Benet was that it did not adequately take into account the age of the test-takers, using only chronological age in its formula, which led to the creation of the Whistler scales with separate tests for different age groups.
Which test is the Kaufman Assessment Battery for Children (KABC) and what does it aim to address?
-The KABC is a well-known IQ test for children that uses tasks common to all people regardless of their cultural background. It was created to address the issue of cultural bias in intelligence testing, ensuring that the test is fair and not influenced by a test-taker's cultural background or other confounding variables.
What is the Ravens Progressive Matrices test and how does it attempt to overcome cultural bias in intelligence testing?
-The Ravens Progressive Matrices is an intelligence test developed by John Raven, based entirely on pictures. This approach attempts to overcome cultural bias by eliminating language barriers and focusing on visual patterns that are universal, making it more accessible to people with different linguistic backgrounds.
What is the Wonderlic test and how is it used by employers?
-The Wonderlic test is an intelligence test used by employers to screen potential employees. It has been linked to job categories, suggesting that certain IQ scores are better suited for specific types of jobs. The test is also used by the National Football League as part of their draft process.
What is the controversy surrounding the use of the Wonderlic test in job categorization?
-The controversy lies in the potential for pigeonholing individuals into job categories based on their intelligence scores, which some argue is an oversimplification and may not accurately reflect a person's capabilities or potential in various job roles.
How does the script suggest the evolution of intelligence testing over time?
-The script suggests that intelligence testing has evolved over time by addressing issues with previous tests, such as cultural bias and age-appropriateness, leading to the development of new tests like the Whistler scales, KABC, and Ravens Progressive Matrices.
What is the fundamental question raised in the script about quantifying intelligence?
-The script raises the fundamental question of whether intelligence, a complex phenomenon, can be quantified into a simple number, pondering the responsibility and accuracy of reducing such a multifaceted concept to a single numerical value.
What is the script's stance on the quantification of intelligence?
-The script acknowledges the complexity of intelligence and the potential irresponsibility of quantifying it, but also notes that intelligence testing has been studied for over a century and that measures are improving rather than deteriorating.
What additional insights does the script offer on the topic of intelligence testing?
-The script offers insights into the history and development of various intelligence tests, the issues they aim to address, and the ethical considerations of quantifying intelligence and its use in categorizing individuals for job suitability.
Why might the script include bad jokes in the presentation?
-The inclusion of bad jokes is likely an attempt to lighten the mood and engage the audience during the presentation, making the topic of intelligence testing more approachable and less dry.
Outlines
π Diverse Intelligence Testing Methods
The script discusses various intelligence tests, highlighting the Whistler scales as a popular alternative to the Stanford Benet. Whistler's scales address the limitation of not considering age by creating separate tests for children, adults, and preschool/primary age groups. The script also mentions the Kaufman Assessment Battery for Children (KABC), which is designed to minimize cultural bias by using universally known tasks. It raises the fundamental question of whether intelligence can be quantified into a single number, suggesting that while intelligence is complex, our measures are improving over time. The script also introduces Ravens Progressive Matrices, an intelligence test based on visual patterns to reduce language bias, and the Wonderlic test, used by employers and the NFL for screening potential employees and draft candidates.
π The Wonderlic Test and its NFL Adoption
This paragraph delves into the use of the Wonderlic test by the National Football League as part of their draft process. The Wonderlic test is noted for linking IQ scores to job categories, suggesting certain scores are better suited for specific jobs. The script expresses skepticism about pigeonholing people based on their intelligence scores and implies that such categorization might be too simplistic. It provides an example of job categories associated with different Wonderlic scores, ranging from systems analysts and chemists at the higher end to janitorial and security guard roles at the lower end, illustrating the test's application in professional sports.

Transcripts
so when we talk about intelligence
testing um we can talk about some of the
tests that are out there other than the
Stanford Benet because they certainly
have developed over the years um one of
the most popular ones and one that
you'll probably see as a teacher when
you're reviewing um um student files and
things of that nature um is the Whistler
scales and this um this basically uh
what Wisher noticed about the Stanford
Benet is that the um the test really
didn't take account into account age
other than the formula taking in
chronological age and so they used the
um so he created Wisher created um three
different tests for three different age
groups so he has The Wisher intelligence
scale for children which is the one
you're probably most most likely to come
across the Whistler adult intelligence
scale which you might come across too as
well if you're in the higher grades
because students with exceptionalities
can go to school until 21 in Ontario um
so that's something you might see uh and
less likely
um to see is the prary uh preschool
primary scale of intelligence um so
these are um our measures of
intelligence that Wisher has provided us
with um oh by the way there's going to
be a handful of uh bad jokes in the
pictures so feel free to pause and check
them out they're um usually I'm the only
one laughing when when they're in class
but thanks to the distance education um
you know we'll save I'll save you that
that
trouble um so we'll talk about a few
other tests that have been created uh
along the way again each of these tests
were created in response to um some
problem that the researchers noticed
about the original Stanford banet so the
Kaufman assessment battery for children
the KABC is a well-known IQ test for
children and it uses tasks that are well
known to all people regardless of
background um so for this one um the
KABC it really um helps to address the
issue of um does your culture
background or whatever um or different
um other factors other confounding
variables affect the test they're trying
to um select for things that are common
to The Human Experience rather than a
particular group which was uh something
that was wrong with the original U
test so there are um many other attempts
or tests to measure intelligence we're
going to talk about a few more here uh
but one fundamental question you can ask
yourself before we get into that is can
we quantify can we turn uh turn
intelligence into a number can we
quantify intelligence um so a simple
number for something so complex this is
a really important thing to ponder
because intelligence is a complicated
phenomenon and um you know it might be
irresponsible to think that we can put a
number on it I don't know it's been
studied for over a century though and um
I think that our our measures of
intelligence are getting better rather
than worse
so another one is called Ravens
Progressive matrices um so again in
response to the cultural bias tests uh
John Raven developed an intelligence
test based completely on pictures and so
for example this so what happened is
people that um had English as a second
language would often score poorer on the
tests and people who are native speaker
speaking uh English assuming the test
was being offered in English as an
example um but this would take away that
that bias here um so you would follow
the pattern right so you look at this
one this one and this one uh this circle
picture circle picture circle picture
and then look at the diamond and then
you'd guess okay what is going to be in
this in you would draw what would be in
this um U Box here so it's basically
completing the pattern right so in this
case it would be a diamond with four
with um with four boxes and the one on
the right hand side would be filled in
because as you can see the Shaded box is
moving
clockwise this one maybe a little bit
more complicated but I don't think
terribly more complicated um to fill in
the blanks and so on so forth so you can
check any of these out online as well if
you're interested in the different ways
in which researchers U are measuring
intelligence uh one of the most popular
tests for employers uh is called the
wonderlick test and it's an intelligence
test um developed for companies to
screen potential employees um they've
actually linked IQ to job categories
which I think is kind of bold um they're
basically saying if you have if you
score between these ranges then here are
the jobs that you'd be better suited for
which I think is quite a
um again a bold uh thing to put out on
their website I'll show you what that
looks like in a minute um here one
moment I think I have it open yeah here
it is okay so we'll take a look at the
JB job categories um as well so this um
my screen's a little small here but uh
here's okay so here's some examples
so their wonderl test is out of 40 and
so um wonderl score by job title um
systems analysist chemists are at the
high end of things on the lower end of
things uh janitorial work um uh and
things like that um security guard etc
etc um I think this is a little bit bold
I don't like to pigeon hole people um
into categories based on um their
intelligence so um I mean I'll let you
draw your own conclusions regarding
that um this was a test that was
actually adopted by the National
Football League and so um they actually
take this test and it's part of their
draft
