Approaches to Improving Intelligence

In this Section of the Journal of Intelligence we invite papers that address ways to improve human intelligence. These papers could be focused at the group, societal or individual level. How can we improve intelligence in our society or at an individual level, and what are specific strategies (biological, educational or otherwise) that improve cognitive performance? At the societal/group or individual level these could include participants of all ages (e.g., addressing cognitive decline in the elderly or boosting IQ in the young).
