Many researchers still argue that cognitive abilities measured by IQ tests have a predominantly genetic basis. But there's very little evidence to support the view, despite hundreds of millions of dollars spent on research to identify genes responsible for intelligence and cognitive ability.

Even if we could identify intelligence genes, the assumption that they work independently of the environment is incorrect. We know that genes get turned on and off depending on environmental cues and triggers.

Creating better environments at sensitive periods of development is likely to have profound effects on our intelligence. Some studies show, for instance, that nutritional interventions can improve cognitive performance, although there's much work still to be done in this area.

The construct of human intelligence is fundamental to the sort of society that we live in; intelligence is central to new discoveries, to finding solutions to important problems, and to many other important qualities we value. Numerous questions remain about not just how to measure intelligence but also how we improve intelligence and prevent our cognitive abilities from declining as we get older.
