IQ is a very strong metric predictor of pretty much every aspect of personal success, from successful marriages to income to academic achievement to interpersonal skills. By no means is the relationship deterministic, but that isn't what we mean by predictors. (Many other psychological metrics, like the nonsensical "emotional intelligence", predict nothing when IQ is included in the mix.)
You really should provide some sort of reference on that claim.
I would say, that the consensus among psychologists in academia is the opposite of what you suggest:
A majority of those people would admit that genes have a significant influence on differences in human behaviour, interests, capabilities etc.

I have myself read 'The Blank Slate' by Steven Pinker. A very recommendable book)
To be clear, men and women are equally mentally gifted as a whole, but focused on different skills, and with bigger variance in men.
Pinker's "Blank Slate" lays out the case well:
However, ideology can influence us, since we are not perfect at science. Without the strong objective feedback of the hard sciences, social psychology is particularly vulnerable.
The bias alleged in this article actually starts to look more plausible when you consider the history of social psychology and related fields. Back in the 1970s, it was taboo to mention ANY innate qualities of human nature. Gender was purely a social construction. Babies were identical in every way--people were different only because of their upbringing. Prominent biologists like E.O. Wilson who argued genes might play a role were attacked and demonized. Nothing could contradict this doctrine of the blank slate -- that we're born perfectly malleable. I highly recommend Steven Pinker's 2002 book, titled "The Blank Slate"  which brilliantly debunks this theory, and lays out the best characterization of human nature I've ever come across. Seriously, read this book, it is a masterpiece.
Anyway, from what I've read recently, it seems many fields like social psychology are still captive to lesser versions of the blank slate fallacy. Human nature is not as malleable as they think. Our instincts are still there (gotta eat, sleep, procreate), and even "higher" areas of the brain for things like language, emotion, and thought seem to be heavily innate (to think at all requires machinery, and there are many ways to craft that machinery). Also, genes really are more important than most seem to realize. The twin and adoption studies show that the majority of variation among people in intelligence and personality is due to genes. How your parents treated you and brought you up has almost no effect by the time you are an adult in important metrics like IQ and personality tests. Smart people are largely born smart.
These sort of "deterministic" ideas fly in the face of traditional liberal values. Topics like gender discrimination and societal inequality are undermined by these ideas, so that provides a reason for a liberal thinker to push back against them.
If the gender gap in computer science is due more to innate differences in interest than to discrimination, and if inequality of income is due more to innate differences in talent than differences in opportunity, then that makes it harder to argue for reform. I believe thinking along these lines is the major cause for bias today.
So yes, I agree social psychology is quite biased. In the future, we will look back with horror at how we let politics and ideology interfere with science.
Given the dramatically different reproductive incentives for women (one egg per month for ~25 years, 9 months of pregnancy plus lactation, etc.) and men (millions of sperm per week and potentially no more than a few minutes' commitment), biologically determined cognitive and behavioral differences are obviously the null hypothesis. In other words, the burden of proof is on those who claim that women and men don't exhibit cognitive dimorphism. Does this strike you as the "mainstream" view? For example, there are many who claim (or, much more often, merely imply) that women and men must on average be equally well-suited to engineering. Are such people routinely called out by NPR and the New York Times to produce evidence to support their position? Um, no. So, we can see that the mainstream is in error: even if it turns that there is such evidence, the mainstream doesn't generally demand it. (Indeed, those who do demand it risk censure for their beliefs.)
A survey of different cultures around the world tends to confirm the null hypothesis: a belief that women and men have different natures is a human universal.  For a rigorous account of the positive case that women and men differ in their cognitive and behavioral characteristics, I can recommend The Blank Slate by Steven Pinker.  If you're short on time, see his TED talk for a quick overview. 
: If creationism were mainstream, Wikipedia would claim a "controversy" over evolution. Indeed, many creationists make just such a claim. This doesn't make them right.
The twins' father, Walker Inman, 57, lumbered from the
mansion, his tattooed sleeves visible under a black T-
shirt, drinking his morning rum ... He'd been full of
dangerous mischief since he was a child. As a 13-year-old
orphan in 1965 taken in by his aunt Doris Duke, Walker –
then called "Skipper" – had romped around her lavish
14,000-square-foot Hawaiian estate without regard for
property or propriety
 Celebrities and athletes are of course excluded from this sentence. They don't become wealthy through scaling businesses/managing people, and as such have a much higher incidence of behavioral issues. Many NBA and NFL athletes are bankrupt after a few years out of the league, in fact.
The Minnesota psychologist and her colleagues found that
disparity could be due as often to innate factors such as
perinatal care or his birth parents' genes. "The
deleterious effects may quite possibly have come before the
adoption ever took place," Keyes, the study's lead
“As always, the children who are most at risk are exactly
the very many children in our society who have the fewest
resources,” Alison Gopnik, a psychologist at the
University of California, said in an e-mail.
Parents who read a lot to their children have children who grow up to be more verbal. But parents who read a lot to their children also tend to pass on genes for verbal fluency. Studies that adequately control for genes show that reading to children does virtually nothing for their verbal ability—it's all in the genes, and in random events over which the parents have no control.

The book The Blank Slate was published almost a decade ago
and research has moved on. The chapter in The Blank Slate that has the most to do with heritability of cognitive abilities is largely based, as author Steven Pinker acknowledges in his bibliographic references, on the work of Eric Turkheimer. But Turkheimer has revised his point of view in the last decade, and if Pinker is still reading Turkheimer's writings, Pinker should too. I'll recommend here two articles from Turkheimer's faculty web page
that more readers of Pinker's book ought to know about, to bring their understanding of human behavioral genetics up to date.
Johnson, Wendy; Turkheimer, Eric; Gottesman, Irving I.; Bouchard Jr., Thomas (2009). Beyond Heritability: Twin Studies in Behavioral Research. Current Directions in Psychological Science, 18, 4, 217-220
is an interesting paper that includes the statement "Moreover, even highly heritable traits can be strongly manipulated by the environment, so heritability has little if anything to do with controllability. For example, height is on the order of 90% heritable, yet North and South Koreans, who come from the same genetic background, presently differ in average height by a full 6 inches (Pak, 2004; Schwekendiek, 2008)."
Another interesting paper,
Turkheimer, E. (2008, Spring). A better way to use twins for developmental research. LIFE Newsletter, 2, 1-5
admits the disappointment of behavioral genetics researchers.
"But back to the question: What does heritability mean? Almost everyone who has ever thought about heritability has reached a commonsense intuition about it: One way or another, heritability has to be some kind of index of how genetic a trait is. That intuition explains why so many thousands of heritability coefficients have been calculated over the years. Once the twin registries have been assembled, it’s easy and fun, like having a genoscope you can point at one trait after another to take a reading of how genetic things are. Height? Very genetic. Intelligence?
Pretty genetic. Schizophrenia? That looks pretty genetic too. Personality? Yep, that too. And over multiple studies and traits the heritabilities go up and down, providing the basis for nearly infinite Talmudic revisions of the grand theories of the heritability of things, perfect grist for the wheels of social science.
"Unfortunately, that fundamental intuition is wrong. Heritability isn’t an index of how genetic a trait is. A great deal of time has been wasted in the effort of measuring the heritability of traits in the false expectation that somehow the genetic nature of psychological phenomena would be revealed. There are many reasons for making this strong statement, but the most important of them harkens back to the description of heritability as an effect size. An effect size of the R2 family is a standardized estimate of the proportion of the variance in one variable that is reduced when another variable is held constant statistically. In this case it is an estimate of how much the variance of a trait would be reduced if everyone were genetically identical. With a
moment’s thought you can see that the answer to the question of how much variance would be reduced if everyone was genetically identical depends crucially on how genetically different everyone was in the first place."
I've enjoyed learning about this line of research from several well known behavioral geneticists, including some of the doyens of twin research, as I participate in the journal club in individual differences psychology and behavioral genetics
at the university where those researchers are based. There is always lively discussion on what the data show, and what the data don't show. Thus far, there are no data to show that poor people are poor solely because they lack academic ability (and anyway studies show
that poverty is a meaningful disadvantage even for high-ability young people).
Nor is there any predictable limit on how much poor people might be able to use their abilities, whatever their current ability level, to improve their condition in life if the undeniable disadvantages of lacking money were alleviated.
IQ is history-correlative
IQ determines life success and more
Faster evolution means more ethnic differences
IQ and all other traits are heritable
Pinker is a liberal but he's also a scientist, and so it's a good intro into reality.
Completely laughable, and completely unverifiable. The only passable tests of such things that I am aware of are studies of separated twins, which have indicated quite clearly, time and time again, that variance in intelligence is attributable in great part to inheritance. There's no arguing around such tests--bring up as many chimpanzee breeds that you want.
Meaning that "intelligence" is largely learned, mind is an empty plate of neurons waiting to be connected.
The oldest error in the discussion. Start your elementary education in the subject here:
Pinker spends an enormous amount of time bowing down to the antique emotionalisms of the age, and so the book shouldn't be too offensive to the weak-hearted.
