From Claude: Yes, there's reasonable evidence the SAT has become somewhat less g-loaded over time, mainly driven by the test's redesigns. The core pattern: The pre-2016 SAT (especially before the 2005 writing section was added, and before 1995 recentering) leaned more heavily on abstract reasoning, analogies, and "trick" items — content that closely mirrors traditional IQ test items. Later redesigns (2005, 2016, and the 2024 digital adaptive version) shifted the test toward more curriculum-based, achievement-oriented content — passage-based reading, grammar/usage, and applied math — which is more coachable and more dependent on specific learned material rather than pure fluid reasoning. What the research shows: •The old pre-2016 SAT had more puzzle-like items testing given information, and a Frey and Detterman study found it correlated more strongly with IQ than the ACT (roughly .88 vs .77), while the new SAT is closer to the ACT in this respect •The SAT's scales and structure changed in the 1995 recentering, then again in 2005, 2016, and 2024 with the shift to digital adaptive testing, and Frey and Detterman themselves cautioned that their original conversion equation may not hold for recentered/redesigned scores •Follow-up work has confirmed the general SAT-g link, with correlations ranging roughly 0.5 to 0.9 depending on sample — but that range itself reflects how much the estimate shifts depending on which era's test and which population you're looking at A separate but related trend: There's also research suggesting the SAT's math section specifically has gotten less rigorous over the 2008–2023 period, independent of g-loading — one analysis found a decrease in SAT math test difficulty from 2008 to 2023, alongside declining student math performance. Bottom line: The trend is toward the SAT prioritizing measurable academic skills and predictive validity for college performance over raw resemblance to an IQ test — a deliberate design choice by the College Board, not necessarily a flaw. But it does mean the strong SAT≈IQ equivalence popularized by the original Frey & Detterman study applies best to older versions of the test, and gets shakier the more recent and redesigned the version you're talking about.
