Chapter Summary

This chapter has offered an understanding of the past, present and potential future of intelligence and has hopefully piqued your interest in some of the thorny theoretical debates concerning how researchers and scholars try to figure out how the human brain performs complex cognitive tasks. We have highlighted the major figures in intelligence work in the field of psychology and provided you with some ideas for who and what to look out for in the near future in the field. The next step for you is to think about how intelligence testing and IQ scores are used, in your own life and in many other contexts, for good or ill.
