Mrs Meeker and her husband Robert Meeker worked on a system used in education. She is known for applying Guilford's Structure of Intellect theory ("SI") to creating assessments and curriculum materials for use in teaching children and adults. The premise of SI is that intelligence comprises many underlying mental abilities or factors, organized along three dimensions—Operations (e.g., comprehension), Content (e.g., semantic), and Products (e.g., relations).

The article compared her work to the debunked Myers Briggs Type Indicator. This is something we should not do. The article on Mrs Laurie Helgoe provides all the arguments needed to restrict information on that indicator to that article. It is not best practice to use tools that are ambiguous in its results and therefore using it in comparison is not in the interest of our readers.
