Theory.

It has been observed that humans, pack animals at their core, will create structures wherever they settle.

Within their galaxy, they are plentiful, but they have a tendency to concentrate on the corners of their world that are most hospitable. The most comfortable. Where they can undeniably state that the environment is least suited to challenge their imagination. Where safety is most guaranteed. 

Experiment ZERØGRAND-10288 was designed to gather data from the footwear of randomly selected members of the species. Each pair was outfitted with a simulated personality pre-selected through a peer-reviewed process and tasked with transmitting its findings via a subspace link.

In every case, regardless of the personality, the samples become irreparably corrupted by the rapid adoption of classism, colonialism, and other long-debunked conceits, which continue to plague much of this society as a whole.

In 99.96% of cases, the data confirmed our theory of chronic annihilationism, which posits that revealing our presence to a species infected by these notions would inflict severe psychological damage on our populace and accelerate the younger species toward their path of self-emulsion by approximately 66.6%.
