Read the links in my previous two posts
If you get your "data" from media sources, they are often hyped up for "story" value and don't necessarily reflect what the scientist said or did.
So you're not fudging the data, just following the popular opinion of it.
And all scientists are not the same. That is why we have peer review.
The article is one that I just googled real quick to show my point. It's pretty much standard stuff that intelligence is inherited. I don't really know of any real science that says anything to the contrary. Perhaps you could share some studies/articles with us that indicate that environment is more important than genes, like you said earlier.
There is no evidence either way, not until we know what intelligence is. We haven't even defined it scientifically, we merely distinguish between cognitive and emotional intelligence both of which are terms applied to generally accepted frames of reference. There is also creativity, like that of great artists and composers, which does not fall into either category.
Until we can find a biological basis for intelligence, there is no way we can comment on its having a genetic basis.
As for what we know:

But we can measure applied intelligence by IQ testing. OK it's not the be all and end all, but serves as a comparison of averages of sorts. On average dumbasses tend to score badly at this.
The only thing IQ testing measures is IQ.
Yes, which stands for 'intelligence quotient'. Intelligence was the discussion here was it not!?!
I mean the concept not the variable.
Your IQ changes with age, education, language, state of mind, blah blah
Not a biological variable and in many cases, not representative of anything more than abiltity to think in a certain way. Does not really make allowances for depth and creativity in thinking.
It like taking body weight as a sign of health. If its very low, theres obviously something wrong, but when its high, can you really tell what it represents?
Again people with a lower IQ tend to be less creative.
I dont know what your trying to prove here, you seem to be proving my point rather than your own. Body weight is a rough indicator of health the same as IQ is a rough indicator to intelligence. Therefor if on average fat people have 1 or 2 less IQ points it's a good sign of a correlation, just as on average the slightly overweigh have more health problems than the normal weighted(this of course is even more so when you compare the health problems of the clinically obese to normal weighted individuals).
No correlation between IQ and creativity. IQ does not measure creativity.
Slightly overweight people have better health indices than "normal" weight people so your statement is false. There is no correlation between overweight and health, only obesity and health. Obesity, as defined by BMI greater than 30 is also a false representation since BMI greater than 30 is also found in athletes with higher muscle mass. Hence obesity by definition is not always accurate.
An inference derived from two values based on assumptions (BMI and IQ) is a logical fallacy.
There is indeed a correlation between IQ and creativity!
Huh? Slightly overweight people by its very definition are disadvantaged to normal weight people in terms of health. You must be using a different definition from the health professionals. Anyway it's irrelevant from the point - that point being that there may be correlations between IQ and weight just as there are indeed correlations between certain weight categories and health.
No its not! if the is a correlation between the two figures. It is indeed logical to assume that obesity has a correlation to IQ if you eliminate error.
http://en.wikipedia.org/wiki/IQ
Populations with slight overweight have longer lifespans
So if your inference about obesity is based on the assumption that BMI measures obesity and your inference about intelligence is based on the assumption that IQ measures intelligence what is your inference about the correlation between BMI and IQ based on?
How would you eliminate error?
Heritability:
the fraction of the variability in a trait that is caused by genetic differences.
www.canine-genetics.com/glossary.htm
The extent to which a trait is influenced by our genetic makeup.
www.iffgd.org/GIDisorders/glossary.html
The degree to which a characteristic is determined by genetics
www.phgu.org.uk/info_database/glossary.html
A measure of the extent to which a feature is inherited; that proportion of variation of a trait in a population that is due to the variation of genotypes.
www.modernhumanorigins.com/h.html
The proportion of the total phenotypic variation of a trait that has a genetic basis.
www.glostercanary.co.uk/gloster.co19.htm
The proportion of variation in a trait among individuals in a population that can be attributed to genetic effects.
www.bscs.org/onco/glossary.htm
The proportion of risk of developing a trait that is atributable to genetic variation, within a specific range of environmental conditions (h 2 ).
www.jcu.edu.au/fmhms/school/pms/CGC/DictGenetics.html
Strictly, the ratio of genetic variance to phenotypic variance. See also narrow-sense heritability and broad-sense heritability.
www.fgcouncil.bc.ca/doc-glos.html
A measure of the strength of the relationship between performance (phenotypic values) and breeding values for a trait in a population. Heritability in the broad sense.
www.alpacas.com/AlpacaLibrary/GlossaryGL.aspx
proportion of trait variance attributable to genetic factors
www.qub.ac.uk/bb/prodohl/TroutConcert/fr_glossary.htm
The proportion of total variance in a trait due to genetic variation. This measure is not always the same; the actual value depends on the degree of environmental variation in any population.
highered.mcgraw-hill.com/sites/0767430220/student_view0/glossary.html
"The amount of variation of a particular trait within a population that is caused by genetic, as opposed to environmental, differences."

Sam,
Do you think that what we classify as "General Intelligence" is a trait bestowed upon a blank mind, by the environment, from birth?

Retesting! If the figures show a correlation after 100's maybe 1000's of runs then you can say that you have pretty well eliminated error, but OK nothing can be 100% error free.
