Actually, there are three ways to increase your intelligence -
First, continually expand the scope, source and intensity of the information you receive;
Second, constantly revise your reality maps, and seek new metaphors about the future to understand what's happening now;
And last, but not least, develop external networks for increasing intelligence. In particular, spend all your time with people that are as smart or smarter than you. We assume that you are the Intelligence Agent from your gene pool, so you will seek Intelligence Agents from other gene-pools who will stimulate you to get smarter.
