What do the problem-solving questions measure in sections 2 and 4 of the Plum Discovery Survey?

The problem-solving section makes use of Raven’s Progressive Matrices, a well-established method for measuring fluid intelligence. We used this method for two reasons - first, we wish to capture an applicant's ability to solve problems based on new information, without relying on past knowledge.

This type of intelligence (fluid intelligence) is particularly important for learning new things. Second, we specifically wanted to avoid verbal or numeric problems because those items are used to capture crystallized intelligence - the type of intelligence that comes from acquired knowledge from schooling or previous experience. It has been argued that measures of crystallized intelligence can lead to adverse impact against protected groups.
