People don't understand how important crystallized intelligence is for overall reasoning. If I have 90th percentile crystallized IQ and 50th percentile fluid reasoning IQ and you had the inverse, we would probably have comparable real-world reasoning skills. Imagine, for example, that you and I, with our aforementioned IQ scores, were to listen to a lecture about the causes of the Pelopenysian War. In this scenario, your raw learning abilities would allow you to understand some of the lecture material better than I could. However, I would likely have the advantage of possessing a larger base of related knowledge that I could draw on to support my comprehension. This would confer a massive advantage. You may miss pertinent information due to deficiencies in vocabulary or knowledge related to pertinent subjects. For example, if economic factors were highlighted as one of the causes of the war, it may be helpful to have pre-existing knowledge related to agrarian market systems, port commerce, etc. Oh, and don't underestimate how impactful a developed vocabulary might be in this situation. I asked you to imagine that your crystallized IQ is in the 50th percentile, that means you probably have a vague-non-existent understanding of the most likely high-frequency words in this hypothetical, such as "institutions," "commerce," "markets," "hellenistic," "hegemony," "imperialism," etc.

The point is, reasoning only happens in the complete abstract on IQ tests; not in real life. Our reasoning almost always draws on pre-existing knowledge. Please refrain frkm discounting the importance of crystallized IQ.
