I thought this part below was interesting. We know that the most selective schools weigh non-academic factors, and many well-off parents are not willing to pay $75/K for a "name" school, so it's reasonable to replace a school filter with a cognitive test.

"Most of the people Vista hires score highly on the cognitive test. Often they are young employees with less-impressive credentials or experience. These HPELs, as they are known, may have gone to state universities and be willing to do a job for $75,000 that an Ivy League graduate in a high-cost market would demand twice as much for."
