Cuil is all well and good, but what purposes can it serve for mankind? This section of the site should deal with how Cuils can be used in various applications.

The brain's interpretation of its surroundings is, following the current definition of Cuil Theory, between 0‽ and 1‽. Autistic individuals are believed to experience life at a lower Cuil level than the average human, and thus have a more accurate, unfiltered view of reality. But this accuracy and lack of filtering leads to complications with human interaction which requires a certain degree of Cuilty.

One of the few situations in life where someone actually experiences something far from reality, or a high level of Cuil, is after ingesting hallucinogenic drugs. Even non-hallucinogenic but mind-altering chemicals have the potential to induce low levels of reality abstraction. Highly hallucinogenic chemicals like DMT have the ability to make the user experience levels 5 or 6 of the Cuil scale, making the Cuil scale a perfect yardstick for measuring how far one's perception of reality was altered during a hallucinogenic drug-induced experience.
