(18,883 posts)Tests and factors this year.
I had the opportunity to take actual IQ tests administered by a licensed psychologist. Unlike online tests, it was a variety of written, verbal and physical tests over several sessions.
We also discussed how the tests work, the limitations and factors in developing IQ.
Your point, nature v nurture, is partially correct. There are several natural factors, not all of which can be directly quantified, which combine to give an individual a theoretical maximum IQ. This would include things such as genetics, birth and internal cranial capacity.
Nurture and development affect how much of that theoretical maximum is developed. This includes everything from childhood home life to nutrition to educational opportunities.
Additionally there are the factors of the individual's test taking ability, the skill of the test administrator/evaluator and cultural background. The psychologist admitted that in the past the tests did tend to result in a reduction of score of non-whites. Despite changes to the tests and methods this has not been fully rectified.
One last Factor is the tests become increasingly imprecise the farther then subject varies from the norm of 100. Many psychologists believe the tests are too inaccurate above 130 and should instead consider how many standard deviations the subject is above or below 100
