Nurture is much more influential in the upbringing of a human than nature is.

I will be arguing that no matter the genetic coding of a certain child (save for genetic disorders such as mental retardation), the upbringing and rapidity of bombardment with information imposed on said child will determine their intelligence and intellectual capabilities (eg. problem solving) much more than genetics.


I accept.

I will be negating the resolution by establishing that genetics plays a larger role in intelligence than upbringing.

The most accurate measure of one's intelligence we have is the IQ test (intelligence quotient test). Modern psychologists place the heritability of IQ at 0.7-0.8 [1], meaning one's IQ score is between 70-80% genetic, 30-20% due to environment. Already I've established that nature plays a more prominent role than nurture, but to ground this in something more tangible, let's look as what's known as the Abecedarian Early Intervention Project.

The Abecedarian Early Intervention Project was a controlled experiment conducted in the 1970's in order to test the benefits (if any) that come with rigorous early childhood education using all of the most modern methods available [2]. The study included over 100 new borns, of which about half were subject to high-quality early intervention education while the other half served as the control group.

The study followed up with its participants at ages 3, 4, 5, 6.5, 8, 12, 15, 21, and 30, and what they found was that at each follow-up, the IQ gap between the two groups shrank. By age 21, the IQ difference between the two groups was only a little over 4 points:

It's worth noting that psychologist Herman Spitz has noted that a mean IQ difference of similar magnitude to the final difference between the intervention and control groups was apparent already at age six months (note the graph), indicating that "4 1/2 years of massive intervention ended with virtually no effect." [3] Even if the 4.5 IQ point gap was due to the project, a gap that small is not considered to be statistically significant, as the standard deviation for IQ is 15 points [4]. Finally, by age 30, the IQ difference between the two groups was no longer considered significant enough to report.

As it turns out, genes express themselves more as we age, meaning that the effects early interventionism on IQ eventually get washed out due to genetic factors, further proving that nature has a greater effect on intelligence than nurture.


The science is clear. The vast majority of one's intelligence comes down to genetics, and early intervention studies have failed to show otherwise. In fact, their findings are very much in-line with my position. The resolution has been negated.

My opponent has forfeited his first round, so I wanted to keep this round brief to give my opponent a chance to re-bound should he come back. Hopefully this debate won't turn into a full forfeit, but we'll just have to wait and see.

"May I have your attention please?
May I have your attention please?
Will the real Slim Shady please stand up?
I repeat, will the real Slim Shady please stand up?
We're gonna have a problem here..

Y'all act like you never seen a white person before
Jaws all on the floor like Pam, like Tommy just burst in the door
and started whoopin her a-- worse than before
they first were divorce, throwin her over furniture (Ahh!)
It's the return of the... "Ah, wait, no way, you're kidding,
he didn't just say what I think he did, did he?"
And Dr. Dre said... nothing you idiots!
Dr. Dre's dead, he's locked in my basement! (Ha-ha!)
Feminist women love Eminem
[*vocal turntable: chigga chigga chigga*]
"Slim Shady, I'm sick of him
Look at him, walkin around grabbin his you-know-what
Flippin the you-know-who," "Yeah, but he's so cute though!"
Yeah, I probably got a couple of screws up in my head loose
But no worse, than what's goin on in your parents' bedrooms
Sometimes, I wanna get on TV and just let loose, but can't
but it's cool for Tom Green to hump a dead moose
"My bum is on your lips, my bum is on your lips"
And if I'm lucky, you might just give it a little kiss
And that's the message that we deliver to little kids
And expect them not to know what a woman's clitoris is
Of course they gonna know what intercourse is
By the time they hit fourth grade
They got the Discovery Channel don't they?
"We ain't nothing but mammals.." Well, some of us cannibals
who cut other people open like cantaloupes [SLURP]
But if we can hump dead animals and antelopes
then there's no reason that a man and another man can't elope
[*EWWW!*] But if you feel like I feel, I got the antidote
Women wave your pantyhose, sing the chorus and it goes

[Chorus: Eminem (repeat 2X)]

'Cause I'm Slim Shady, yes I'm the real Shady
All you other Slim Shadys are just imitating
So won't the real Slim Shady please stand up,
please stand up, please stand up?

Will Smith don't gotta cuss in his raps to sell his records;
well I do, so f--- him and f--- you too!
You think I give a damn about a Grammy?
Half of you critics can't even stomach me, let alone stand me
"But Slim, what if you win, wouldn't it be weird?"
Why? So you guys could just lie to get me here?
So you can, sit me here next to Britney Spears?
S---, Christina Aguilera better switch me chairs
so I can sit next to Carson Daly and Fred Durst
and hear 'em argue over who she gave head to first
You little b----, put me on blast on MTV
"Yeah, he's cute, but I think he's married to Kim, hee-hee!"
I should download her audio on MP3
and show the whole world how you gave Eminem VD [AHHH!]
I'm sick of you little girl and boy groups, all you do is annoy me
so I have been sent here to destroy you [bzzzt]
And there's a million of us just like me
who cuss like me; who just don't give a f--- like me
who dress like me; walk, talk and act like me
and just might be the next best thing but not quite me!


I'm like a head trip to listen to, cause I'm only givin you
things you joke about with your friends inside your living room
The only difference is I got the balls to say it
in front of y'all and I don't gotta be false or sugarcoated at all
I just get on the mic and spit it
and whether you like to admit it [*ERR*] I just s--- it
better than ninety percent of you rappers out can
Then you wonder how can kids eat up these albums like valiums
It's funny; cause at the rate I'm goin when I'm thirty
I'll be the only person in the nursin home flirting
Pinchin nurses a---- when I'm jackin off with Jergens
And I'm jerkin but this whole bag of Viagra isn't working
And every single person is a Slim Shady lurkin
He could be workin at Burger King, spittin on your onion rings
[*HACH*] Or in the parkin lot, circling
Screaming "I don't give a f---!"
with his windows down and his system up
So, will the real Shady please stand up?
And put one of those fingers on each hand up?
And be proud to be outta your mind and outta control
and one more time, loud as you can, how does it go?

[Chorus 4X]

Ha ha
Guess there's a Slim Shady in all of us
F--- it, let's all stand up" [1]
