Our work on intelligence covers three topics: prototypes of intelligence; reputational measures of intelligence; use of the OCT.

1. Exemplar surveys
   
   Following the exemplar literature, we asked lay observers for examples of intelligent people.


2. Reputational measures
   
   There are difficulties with defining intelligence with either psychometric or subjective methods. The reputational method works well with older patients.


3. OCT as a measure of cognitive ability
   
   When applied to a large set of academic items, the overclaiming technique can be used the measure global intelligence. The accuracy index provides an easy and valid method for controlling the research. We have recently extended this work into 'non-academic' or 'lay' domains. We have included myriad domains from music to movies to macho sports (e.g., pro wrestling, NASCAR).
