The chief advantage that the Maya and Aztec had over the Inca in managing information was writing. While all three civilizations had their own unique systems for recording and managing information, the ability to write gave the Maya and Aztec an advantage in terms of the comprehensiveness and durability of their records.

The Maya developed one of the most advanced writing systems in the ancient Americas, which consisted of hieroglyphs that represented both sounds and ideas. This widespread writing system allowed them to record historical events, genealogies, astronomical observations, agricultural practices, and other aspects of their civilization. It also enabled them to create complex literary works, including myths, legends, and religious texts.

Similarly, the Aztec civilization developed a sophisticated writing system known as "pictograms," which used images and symbols to represent words and concepts. This system was used for a variety of purposes, such as keeping track of tribute payments, historical events, and religious rituals. The Aztec also produced narrative texts that recorded their history and legends.

In contrast, the Inca civilization did not have a writing system. Instead, they relied on a system of knotted strings known as quipu to record and communicate information. Quipu consisted of colored and knotted strings of different lengths, which were used to represent numbers, dates, and even narratives. However, the quipu system was primarily used for numerical and accounting purposes rather than recording extensive texts or complex information.

While the Inca effectively used quipu for administrative purposes, the lack of a proper writing system limited their ability to record and manage a wide range of information in the same comprehensive manner as the Maya and Aztec. This disadvantage is particularly evident when it comes to historical records and complex literary works, where the Maya and Aztec had a clear advantage due to their developed writing systems.
