If that were true there could be no advancement of the species and we would have never figured out stone tools.
My iq is higher than either of my parents. Theirs are higher than their parents. If everyone keeps paying attention this trend can continue.
The problem is that most people are fine with being retarded and don't actually want more for their kids.

Unfortunately the IQ trends are strongly based on genetics- if you marry right these can change (think of all the Swedish women and the refugee doctors and engineers). If you marry wrong, nose dives can happen (first cousin marriages being supported by religious dogma).
