IQ scores rose across the twentieth century, which makes old test norms easy to beat. What studies found on the size, the possible causes and the declines in some recent samples, and what it means for your score.
IQ can rise a little, mostly through years of education. Brain-training games show no reliable gain, and a retake score reads high on average. What controlled studies found, with sources.
Abstract reasoning means finding the rule behind patterns you have not seen before. What it is, everyday and test examples, how it relates to fluid intelligence and IQ, and why the UCAT dropped its section.
IQ and emotional intelligence are measured in very different ways. What each score means, how much they overlap, what research says each predicts at school and work, and where the popular EQ numbers come from.
A full IQ test such as the WAIS-5 (Pearson, 2024) samples five abilities and combines them into one score. Raven's matrix test uses a single type of item (APA task force, 1996).
Raven's Progressive Matrices are nonverbal reasoning tests in which you pick the piece that completes a pattern. Scores are compared with an age-based norm group, and the test uses only one kind of puzzle.
Fluid intelligence is the ability to reason and solve new problems without relying on what you already know (PNAS, 2008). Learn how it differs from crystallized intelligence and how it is measured.
