Perhaps the tests are doing exactly what they were calibrated to do. The original purpose of the IQ tests was to predict the level of schooling that a subject would achieve, and the tests were calibrated accordingly. Since students are saying in school longer, for various reasons, the scores are rising as they should.
The only remarkable thing is that the tests work so well, despite the many factors that affect the length of schooling. Perhaps "intelligence" tests should be renamed "perserverance, ambition, school availability and size of parents' bank account" tests.

"Penguins are 10 times older than humans and have been here for a very, very long time," said Daniel Ksepka, Ph.D., a North Carolina State University research assistant professor. Dr. Ksepka researches the evolution of penguins and how they came to inhabit the African continent.
Because penguins have been around for over 60 million years, their fossil record is extensive. Fossils that Dr. Ksepka and his colleagues have discovered provide clues about migration patterns and the diversity of penguin species.
