THEORY ASSESSMENT
The episode ground truth directly confirms the pre-installation knowledge of chip failures and the decision-making authority attached to it, making this theory a near-direct read of on-screen evidence with only the specific vault assignments remaining unconfirmed.
STORY CONTEXT
The central conspiracy of the franchise gets fresh fuel from the show. This thread houses theories connecting individual vault experiments to a unified endgame, whether that's population control, societal engineering, or something apocalyptic.
WHY THIS MATTERS
If the chip assignments followed any targeting criteria at all, Vault-Tec was not a corporation that accepted collateral damage. It was one that calculated specific post-war death counts by community, before the first bomb fell. Lucy's entire journey would not be a story about survival against the odds. It would be a story about someone escaping a scheduled outcome.
ALTERNATE INTERPRETATION
A minority reading treats the chip distribution not as coordinated population culling but as currency in Vault-Tec's internal power struggles. Under this interpretation, condemned vaults reflect factional deal-making between executives rather than any unified targeting ideology. The defective chips were leverage, not policy. This reading does not require a master list, only a series of transactional decisions made by competing managers who each thought they were playing the other. It is a less organized version of the same crime, and it does not make Vault 33's fate any less deliberate. It only disperses the blame.
