In 1922 to 1924, Merrill became one of the three independent reviewers, along with Lewis Terman and Catherine Cox, to read through the 6,000-page manuscript of collected existographic material on the top 300 eminent minds of the Cattell 1000, of adulthood age in the years 1350 to 1850, and to assign them with AI IQs (age 1-16) and AII IQs (age 17 to young adult) of each person, based on the facts of accomplishment of each eminent mind, based on the existographic material.

The following are quotes on Merrill:
- “One rater (Merrill) has scored on the basis of the record of Goethe’s youth an IQ of 225. Goethe’s true IQ may in the history of mankind have been equaled in a few instances; one may well wonder whether it has ever been exceeded?”
