IQs increased by about 30 points in the 20th century. Part of this increase may have been the result of increased standardized testing because testing improves the skills on which students are tested. But although these practices may increase general intelligence, they may impede the development of creativity and wisdom. As a result, our society may be achieving short-term increases in well-being at the expense of long-term ones. Instruction and assessment need to better balance the development of intelligence, creativity, and wisdom.
