00:00:03,440 --> 00:00:03,710
Good
2
00:00:06,140 --> 00:00:08,090
for decades,
ethnic groups have,
3
00:00:08,091 --> 00:00:13,091
on average,
scored significantly differently on Iq
4
00:00:13,091 --> 00:00:16,151
tests.
According to psychology professor
5
00:00:16,151 --> 00:00:19,211
Richard Harris,
whom you interviewed on your channel
6
00:00:19,211 --> 00:00:19,430
Youtube,
there was no scientific consensus on the
7
00:00:19,431 --> 00:00:22,490
causes of these average differences in
Iq test scores.
8
00:00:22,760 --> 00:00:24,110
Yet,
according to Haier,
9
00:00:24,350 --> 00:00:29,350
psychologists do generally agree that
general intelligence exists that Iq
10
00:00:29,721 --> 00:00:34,721
measures that well and in a non
culturally biased way that Iq is highly
11
00:00:34,721 --> 00:00:39,641
predictive of success and educational
and professional terms and that for
12
00:00:39,641 --> 00:00:41,420
decades,
ethnic groups have on average,
13
00:00:41,421 --> 00:00:45,080
scored significantly differently.
So assuming this is true,
14
00:00:45,140 --> 00:00:50,140
should we talk about it?
Sam Harris raised this question and a
15
00:00:50,140 --> 00:00:51,140
podcast conversation with Charles
Murray.
16
00:00:51,860 --> 00:00:56,860
Some argue that we should not talk about
this as doing so could fuel the racial
17
00:00:57,051 --> 00:01:01,370
supremacist movements that you mentioned
with potentially horrific consequences.
18
00:01:01,820 --> 00:01:06,820
Others mainly on the intellectual dark
web and to a very limited extent in
19
00:01:06,831 --> 00:01:11,831
academia.
I think we should talk about this topic
20
00:01:11,831 --> 00:01:13,580
because average differences in Iq scores
have existed for decades.
21
00:01:14,330 --> 00:01:18,200
They may have played a role in
generating the disparate educational and
22
00:01:18,201 --> 00:01:21,380
professional outcomes that we observe
and care about,
23
00:01:21,860 --> 00:01:26,860
and thus that we cannot properly analyze
these disparate outcomes unless we do
24
00:01:26,860 --> 00:01:29,590
talk about the subject openly.
Geneticists,
25
00:01:29,630 --> 00:01:34,630
David Reich recently argued in the New
York Times that have scientists do not
26
00:01:34,630 --> 00:01:37,070
openly discuss the biological basis of
race.
27
00:01:37,400 --> 00:01:41,540
Pseudo scientists could fill the vacuum
with dangerous consequences.
28
00:01:41,990 --> 00:01:43,190
Furthermore,
you,
29
00:01:43,191 --> 00:01:48,191
Professor Peterson are highly critical
of the oppression narrative that
30
00:01:48,191 --> 00:01:52,841
permeates segments of the academy and
activist left and knowledge about
31
00:01:52,911 --> 00:01:56,450
average differences in Iq scores between
ethnic groups,
32
00:01:56,660 --> 00:01:59,990
while tough to assimilate could puncture
this narrative.
33
00:02:00,680 --> 00:02:03,560
So the question is,
what is your view on all that?
34
00:02:03,561 --> 00:02:05,270
I've just said,
Jesus,
35
00:02:05,380 --> 00:02:08,220
you guys already didn't take a long time
to prepare these questions.
36
00:02:08,221 --> 00:02:08,640
Didn't know.
37
00:02:12,050 --> 00:02:12,770
Alright,
so
38
00:02:15,240 --> 00:02:20,240
when I went to Harvard,
I came from mcgill and I had spent a lot
39
00:02:20,881 --> 00:02:25,881
of time with my advisor there and a
research team that he had trying to
40
00:02:27,151 --> 00:02:32,151
understand the genesis of antisocial
behavior and him among adolescents,
41
00:02:33,481 --> 00:02:38,481
mostly so well as kids as well.
It's antisocial behavior is very
42
00:02:38,481 --> 00:02:42,771
persistent.
So if you have a child whose conduct
43
00:02:42,771 --> 00:02:45,051
disordered at the age of four,
the probability that they will be
44
00:02:45,051 --> 00:02:48,030
criminal at the age of 15 or 20 is
extremely high.
45
00:02:48,120 --> 00:02:53,120
It's unbelievably stable.
It's a very dismal literature because
46
00:02:53,120 --> 00:02:57,230
you see these early onset aggressive
kids and and it's persistent and then
47
00:02:58,201 --> 00:03:03,201
you look at the intervention literature
and you throw up your hands because no
48
00:03:03,201 --> 00:03:07,381
interventions work and believe me,
psychologists have tried everything you
49
00:03:07,381 --> 00:03:10,921
could possibly imagine and a bunch of
things that you can't in order to
50
00:03:10,921 --> 00:03:14,641
ameliorate that.
So we're really interested in trying to
51
00:03:14,641 --> 00:03:14,641
understand,
for example,
52
00:03:14,920 --> 00:03:19,920
if you're antisocial by the age of four,
then there isn't an intervention that
53
00:03:19,920 --> 00:03:20,320
seems to be effective.
54
00:03:20,920 --> 00:03:24,340
So,
and the standard penal logical theory is
55
00:03:24,341 --> 00:03:29,341
really quite horrifying in this regard
because what you see is that male
56
00:03:29,341 --> 00:03:33,241
aggression peaks around the age of 15
and then it declines fairly
57
00:03:33,241 --> 00:03:33,241
precipitously and,
and,
58
00:03:33,430 --> 00:03:36,640
and sort of normalizes again by the age
of 27.
59
00:03:36,641 --> 00:03:40,180
And Standard penal logical theory
essentially is this cold hearted.
60
00:03:40,181 --> 00:03:45,181
It's like if you have a mold,
if you have someone who is a multiple
61
00:03:45,181 --> 00:03:48,451
offender,
you just throw them in prison til
62
00:03:48,451 --> 00:03:48,451
they're 27,
then the age out of it,
63
00:03:48,451 --> 00:03:51,580
and that's all there is to it.
That's what we've got.
64
00:03:52,060 --> 00:03:57,060
Now,
there's some downside to that because
65
00:03:57,060 --> 00:03:58,771
there's a corollary literature that
suggests that the worst thing that you
66
00:03:58,771 --> 00:03:59,230
can do with antisocial people is to
group them together,
67
00:03:59,680 --> 00:04:01,690
which is what we do in prisons.
So,
68
00:04:01,720 --> 00:04:03,490
so that's a whole mess.
Anyways.
69
00:04:04,240 --> 00:04:09,240
One of the things we were doing was
trying to see if there might be
70
00:04:09,240 --> 00:04:09,850
cognitive predictors of antisocial
behavior.
71
00:04:09,850 --> 00:04:14,850
And so we use this battery of
neuropsychological tests that was put
72
00:04:14,850 --> 00:04:15,970
together at the Montreal Neurological
Institute,
73
00:04:16,180 --> 00:04:21,180
took about 11 hours to administer and
hypothetically assessed prefrontal
74
00:04:21,180 --> 00:04:23,170
cortical function.
We computerized that,
75
00:04:23,171 --> 00:04:28,171
reduced it to about 90 minutes and then
assessed antisocial adolescents in
76
00:04:29,170 --> 00:04:33,400
Montreal and found out that they did
show deficits in problem solving ability
77
00:04:33,550 --> 00:04:35,230
that we were associated with,
uh,
78
00:04:35,630 --> 00:04:37,880
with prefrontal ability.
Um,
79
00:04:39,220 --> 00:04:40,510
when I got to Harvard,
I thought,
80
00:04:40,511 --> 00:04:41,560
well,
that's interesting.
81
00:04:42,430 --> 00:04:46,750
We could use the neuro psych battery to
predict negative behavior.
82
00:04:47,020 --> 00:04:50,210
Perhaps we could use it to predict
positive behavior.
83
00:04:50,211 --> 00:04:51,010
So I thought,
well,
84
00:04:51,011 --> 00:04:55,360
what if we turned the neuro psych
battery and over and thought,
85
00:04:55,361 --> 00:04:56,650
well,
can we predict grades,
86
00:04:56,651 --> 00:04:57,910
for example,
because you know,
87
00:04:57,940 --> 00:05:01,030
that's a decent thing to predict.
So we ran a study,
88
00:05:01,630 --> 00:05:04,000
we ran a study that looked at Harvard
kids,
89
00:05:04,001 --> 00:05:09,001
University of Toronto kids line workers
at a Milwaukee factory and managers and
90
00:05:09,491 --> 00:05:11,170
executives at the same factory.
91
00:05:11,170 --> 00:05:16,170
And what we found was that the average
score across these neuropsychological
92
00:05:16,840 --> 00:05:18,430
tests,
they were kind of like games.
93
00:05:18,431 --> 00:05:19,660
They were game like,
you know.
94
00:05:19,661 --> 00:05:22,350
So in one,
in one test you had,
95
00:05:22,420 --> 00:05:26,650
there were five lights in the middle of
the screen and a box was associated with
96
00:05:26,740 --> 00:05:28,960
each light and you had to learn by trial
and error,
97
00:05:28,961 --> 00:05:31,330
which box was associated with,
with each light.
98
00:05:31,331 --> 00:05:33,550
That was one of the tests.
Um,
99
00:05:34,210 --> 00:05:39,210
so we took people's average score across
the tests because they seem to clump
100
00:05:39,491 --> 00:05:42,820
together into a single structure.
You can do,
101
00:05:42,850 --> 00:05:45,550
you can find that out statistically.
If you take a bunch of tests,
102
00:05:45,850 --> 00:05:50,850
you can find out how they clumped
together statistically by looking at
103
00:05:50,850 --> 00:05:51,520
their patterns of correlations.
And you might get multiple clumps,
104
00:05:51,521 --> 00:05:54,940
which is what happens with personality
research where you get five or you might
105
00:05:54,941 --> 00:05:57,100
get a singular clump,
which is what happens.
106
00:05:57,440 --> 00:06:00,980
Cognitive research.
And we got a single clump essentially.
107
00:06:01,430 --> 00:06:06,430
And then we were trying to figure out if
at the same time I was reading the
108
00:06:06,430 --> 00:06:10,631
literature on performance prediction and
there's an extensive literature on
109
00:06:10,631 --> 00:06:14,561
performance prediction,
a lot of it generated by the armed
110
00:06:14,561 --> 00:06:14,561
forces,
by the way,
111
00:06:14,561 --> 00:06:17,360
I'm indicating that ICU is a very good
predictor of longterm life success.
112
00:06:17,600 --> 00:06:20,690
And so here's the,
here's the general rule.
113
00:06:21,860 --> 00:06:26,860
If your job is simple,
which means you do the same thing every
114
00:06:26,860 --> 00:06:27,590
day than Iq predicts how fast you'll
learn the job,
115
00:06:27,591 --> 00:06:31,100
but not how well you do it.
But if your job is complex,
116
00:06:31,250 --> 00:06:34,220
which means that the demands change on
an ongoing basis,
117
00:06:34,221 --> 00:06:37,280
then the best predictor of success is
general cognitive ability.
118
00:06:37,790 --> 00:06:41,060
And uh,
and I learned that the general cognitive
119
00:06:41,061 --> 00:06:46,061
ability tests clump together into a
single factor that's fluid intelligence
120
00:06:46,061 --> 00:06:49,980
or Iq.
And then we didn't know if the factor
121
00:06:49,980 --> 00:06:51,680
that we had found was the same factor as
Iq and it.
122
00:06:51,980 --> 00:06:54,590
And we still haven't really figured out
whether or not that was the case because
123
00:06:54,591 --> 00:06:56,540
it kind of depends on how you do the
analysis.
124
00:06:56,840 --> 00:07:01,840
But anyways,
I got deeply into the performance
125
00:07:01,840 --> 00:07:04,631
prediction literature and I found out,
well if you wanted to predict people's
126
00:07:04,631 --> 00:07:04,631
performance in life,
there's,
127
00:07:04,631 --> 00:07:05,750
there's a couple of things you need to
know.
128
00:07:05,751 --> 00:07:07,610
You need to know their general cognitive
ability.
129
00:07:07,611 --> 00:07:11,150
If they're going to do a complex job,
you need to know their trait.
130
00:07:11,151 --> 00:07:16,151
Conscientiousness,
some of you might've heard that
131
00:07:16,151 --> 00:07:17,630
rebranded as grit in a very corrupt act
by the way,
132
00:07:17,880 --> 00:07:22,880
um,
because it's a good predictor of
133
00:07:22,880 --> 00:07:23,780
longterm life success,
freedom from negative emotion.
134
00:07:23,810 --> 00:07:27,980
Low neuroticism is another predictor,
but it's sort of third on the hierarchy.
135
00:07:27,981 --> 00:07:31,100
And then openness to experience which is
a personality trait,
136
00:07:31,101 --> 00:07:34,160
is associated with,
with expertise in creative domains.
137
00:07:34,910 --> 00:07:37,190
The evidence that now I should tell you.
138
00:07:37,370 --> 00:07:42,370
So it's such a complicated question.
I should tell you how to make an Iq
139
00:07:42,370 --> 00:07:45,581
test.
It's actually really easy and you need
140
00:07:45,581 --> 00:07:45,620
to know this to actually understand what
Iq is.
141
00:07:45,621 --> 00:07:50,060
So imagine that you generated a,
a set of 10,000
142
00:07:50,061 --> 00:07:54,170
questions about anything.
It could be math problems,
143
00:07:54,171 --> 00:07:56,360
they could be general knowledge,
they could be vocabulary,
144
00:07:56,361 --> 00:08:01,361
that could be multiple choice.
It really doesn't matter what they're
145
00:08:01,361 --> 00:08:01,370
about as long as they require
abstraction to solve,
146
00:08:01,460 --> 00:08:05,780
so they'd be formulated linguistically,
but mathematically would also apply.
147
00:08:06,290 --> 00:08:08,900
And then you have those 10,000
questions.
148
00:08:08,960 --> 00:08:13,960
Now you take a random set of 100 of
those questions and you give them to a
149
00:08:14,300 --> 00:08:19,300
thousand people and all you do is sum up
the answers right from so some people
150
00:08:19,300 --> 00:08:23,231
are going to get most of them right and
some of some of them are going to get
151
00:08:23,231 --> 00:08:23,231
most of them wrong.
152
00:08:23,231 --> 00:08:23,870
You just rank order the people in terms
of their score,
153
00:08:24,950 --> 00:08:28,790
correct that for age and you have Iq.
That's all there is to it.
154
00:08:29,180 --> 00:08:34,180
And what you'll find is that no matter
which random set of 100 questions you
155
00:08:34,180 --> 00:08:38,111
take,
the people at the top of one random set
156
00:08:38,111 --> 00:08:39,230
will be at the top of all the others and
it with very,
157
00:08:39,231 --> 00:08:41,000
very,
very high consistency.
158
00:08:41,210 --> 00:08:46,210
So one thing you need to know is that if
any social science claims whatsoever are
159
00:08:46,581 --> 00:08:51,581
correct,
then the ICU claims are correct because
160
00:08:52,101 --> 00:08:57,101
the ICU claims are more psychometrically
rigorous than any other phenomena
161
00:08:57,101 --> 00:08:59,430
phenomena that's been discovered by
social scientists.
162
00:08:59,880 --> 00:09:04,880
Now,
the ICU literature is a dismal
163
00:09:04,880 --> 00:09:04,880
literature.
No one likes it.
164
00:09:04,880 --> 00:09:05,220
Here's why.
Here's an example.
165
00:09:05,490 --> 00:09:08,490
So here's a little,
here's a fun little fact for you,
166
00:09:08,730 --> 00:09:13,730
for Liberals and conservatives alike,
because conservatives think there's a
167
00:09:13,730 --> 00:09:13,730
job for everyone.
168
00:09:13,730 --> 00:09:17,420
If people just get off their asses and
get the work and liberals think while
169
00:09:17,420 --> 00:09:17,850
you can train anyone to do anything,
it's like,
170
00:09:18,030 --> 00:09:21,060
no,
there isn't a job for everyone and no,
171
00:09:21,150 --> 00:09:24,240
you can't train everyone to do
everything that's wrong.
172
00:09:24,780 --> 00:09:26,670
And here's one of the consequences of
that.
173
00:09:27,210 --> 00:09:32,210
So as I mentioned,
the Armed Forces has done a lot of work
174
00:09:32,210 --> 00:09:32,330
on ICU when they started back in 19,
19.
175
00:09:32,340 --> 00:09:34,560
And the reason they did that was
because,
176
00:09:34,800 --> 00:09:36,280
well,
for obvious reasons,
177
00:09:36,281 --> 00:09:41,281
say let's say there's a war and you want
to get qualified people into the officer
178
00:09:41,461 --> 00:09:44,190
positions as rapidly as possible or
you'll lose.
179
00:09:44,700 --> 00:09:46,860
So that's a reason.
Now,
180
00:09:46,861 --> 00:09:50,790
the armed forces has experimented with
Iq tests since 19,
181
00:09:50,791 --> 00:09:55,791
19,
and in the last 20 years I'm a law was
182
00:09:55,791 --> 00:09:57,150
passed as a consequence of that
analysis,
183
00:09:57,151 --> 00:10:02,151
which was that it was illegal to induct
anyone into the armed forces who had an
184
00:10:02,151 --> 00:10:02,550
Iq of less than 83.
185
00:10:03,840 --> 00:10:08,840
Now the question is why and the answer
was all of that effort put in by the
186
00:10:08,911 --> 00:10:11,970
armed forces indicated that if you had
an Iq of 83 or less,
187
00:10:11,971 --> 00:10:16,971
there wasn't anything that you could be
trained to do in the military that
188
00:10:16,971 --> 00:10:18,630
wasn't positively counterproductive.
Now you got to think about that a,
189
00:10:18,631 --> 00:10:23,230
because the military is chronically
desperate for people right there.
190
00:10:23,231 --> 00:10:26,640
It's not like they're so like people are
lining up to be inducted,
191
00:10:26,940 --> 00:10:28,890
right?
They have to go out and recruit and it's
192
00:10:28,891 --> 00:10:33,891
not easy and so they're desperate to get
their hands on every body they can
193
00:10:33,891 --> 00:10:36,030
possibly manage and then especially in
war time,
194
00:10:36,031 --> 00:10:38,580
but also in peacetime.
But then there was another reason too,
195
00:10:38,581 --> 00:10:43,581
which was the armed forces,
was also set up from a policy
196
00:10:43,581 --> 00:10:44,640
perspective to take people in the
underclass,
197
00:10:44,641 --> 00:10:47,610
let's say,
and train them and move them up at least
198
00:10:47,610 --> 00:10:49,350
into the working class or maybe the
middle class.
199
00:10:49,351 --> 00:10:52,890
So there's a policy element to it too.
And so even from that perspective,
200
00:10:52,891 --> 00:10:56,040
you could see that the military is
desperate to bring people in,
201
00:10:56,640 --> 00:10:59,850
but it well with an Iq of 83 or less,
it's not happening.
202
00:11:00,900 --> 00:11:05,900
Okay?
