Frequently Asked Questions

Why is the g loading so high?

The composite effect means that the more tests you composite, the more the g loading goes up (goes up in relation to the individual g loadings of the tests). Theoretically, you could take an infinite amount of IQ tests and as you composite them, the g loading would approach 1 (this isn't the case in reality however). Now this, combine the good quality and comprehensive nature of the actual tests, means the resulting g loading is high. Remember, SC-ULTRA is around 4.5 hours of testing time while professional tests of similar g loading take only a fraction of the time.

If quantitative reasoning is apart of Fluid Reasoning in CHC theory, then why is it its own index?

S-C ULTRA does it because the Indexer does it. The Indexer does it because it draws inspiration from SB-V and WISC-V. Why do those tests do it? Probably because they have formed their own theories on g based on but not exactly CHC theory. Personally I think RQ is different enough from RG and I to warrant a different index. Not only is there a slight loading on gq but since SC-ULTRA uses SMART, its not culture fair like RAPM or CAIT FW.

Why was the Compositator removed?

Because the creator of the Compositator has improved on his past work and made an improved derivative, the Indexer.

Why has the FSIQ g loading been decreasing?

New iterations of the testing model prioritizes correlation with g, not FSIQ.

Potential future improvements:

• Validation and addition of the PAT
• Validation of CAIT Symbol Search & Digit Span
• Better eCBT and RAPM set II norms
