  An outstanding mystery of dark matter physics is the lack of direct detection
signals to date. We suggest that dark matter is scatophobic: due to a repulsive
long-range interaction, it is repelled by objects with a large net scat charge,
such as the Earth, and is therefore not able to reach direct detection
experiments. This represents the first step in a broader theoretical paradigm
that we dub the "anti-anthropic principle."
