The first major category of assessment described in Hogan (2007) is intelligence tests. For this reason, there is a multitude of research on the topic. According to Flynn (2009), the "Flynn effect" examines the flaws within IQ tests. Flynn wrote his first book about increasing IQs in the early 80's. He estimates that average IQ has been increasing by 3 points every decade! His newest book is out in paperback:

Flynn, J. R. (2009) What is intelligence? Beyond the Flynn effect. Cambridge: Cambridge University Press.

That's one of the reasons all of the valid and reliable assessments of IQ tests are revamped and reformed every 10 years. Many studies have been conducted which concur with the Flynn effect. If this is true, then my grandmother, who was born in 1888, might have had borderline intelligence, or an IQ score in the 70's. Flynn further believes that we aren't getting smarter as much as we are getting more modern. The research seems to be agreeing with him and when I think about it, look how easy it seems for kids to understand all of the new technology. Children are immersed in our culture of technology and multiple requirements to function as never before.

Can you see how multiple cultural issues impact what is even selected to be on an IQ test? If so Why or Why not?
