There is some evidence that average intelligence has been rising, probably due to improved childhood nutrition, but this is so slow as to be unlikely to be visible betweeen one or even two generations. And also begs the question as to what is 'intelligence', and how do you measure it.
Most examples quoted to show that the this is happening simply show that children today are developing skills that did not exist a generation ago. This has been happening forever, as new technology and practices appear. For example, consider the children who were the first in their family to learn to read and write. Does this make them more intelligent than their parents?
