Superposition is a hypothesized mechanism for polysemanticity. It is a major bottleneck for interpretability. There are groups working on reducing it, most notably Chris Olah's group at Anthropic. However, it is possible that reducing superposition is hard, or that superposition is not an accurate model of polysemanticity.

The following would qualify for a YES resolution:

The following would qualify for a (pre-2026) NO resolution:

In the event that it is unclear how many features are actually in superposition (there could hypothetically be an absurd number of near-orthogonal vectors), only preliminary (and not necessarily conclusive) evidence that the remaining possible directions are not relevant is sufficient to rule them out from consideration.
