About this fun IQ tool
These items are original, but inspired by methods used in cognitive research—fluid reasoning patterns, inductive number series, analogical reasoning, and syllogistic logic. We followed a lean version of the Cattell–Horn–Carroll (CHC) framework with an emphasis on Gf (fluid reasoning).
Representative references: Carroll (1993), McGrew (2009), Schneider & McGrew (2018), Raven et al. (2000), Carpenter et al. (1990), Sternberg (1977/1983), Johnson-Laird (1983/1999), Klauer (1990), Kyllonen & Christal (1990). We use them for inspiration only—no proprietary items appear here.
This playful estimate is not a diagnosis. Official IQ scores require standardized, supervised exams.
