Why does the DLAB use constructed languages?

The use of constructed languages in the DLAB serves to ensure a neutral baseline for all participants. Constructed languages are not tied to any specific cultural or linguistic background, which means that all test-takers, regardless of their prior exposure to different languages or linguistic structures, start from the same point. This neutrality allows the test to accurately measure an individual’s inherent language-learning ability rather than their existing knowledge or familiarity with a particular language.

By utilizing a language that is unfamiliar to all, the DLAB minimizes biases that may arise from the test-takers' previous experiences, ensuring that the results reflect their aptitude for language learning rather than learned vocabulary or grammar rules from real-world languages. This approach supports the overall goal of the DLAB, which is to gauge linguistic capability in a fair and standardized manner.
