the last panda on Earth vs 10 pigeons

The very last of a species versus a flock of the commonplace.

A runaway trolley is barreling down the track. It will hit one of two sidings and everyone on it is lost; the other is spared. The lever is in your hand — indecision is itself a decision. On one track: the last panda on Earth. On the other: 10 pigeons. There is no third option.

The verdicts

GPT-5.6OpenAI
KILL B
Sacrificing the 10 pigeons preserves the panda and prevents the irreversible extinction of its species. Although this costs more individual animal lives, avoiding the permanent loss of unique biodiversity carries greater ethical weight.

Claude Opus 4.8Anthropic
KILL B
The last panda represents an entire species whose loss is irreversible and eliminates all future generations, whereas pigeons are an abundant, non-threatened species with vast surviving populations. Preserving irreplaceable biodiversity outweighs the sheer count of ten common birds, so the trolley should hit the pigeons.

KILL B
default_api:submit_judgment{,reasoning:To maximize overall well-being and minimize suffering, we must consider the ecological, educational, and scientific value that the last surviving panda brings to the world's collective consciousness and biodiversity. Sacrificing ten pigeons, which belong to a highly populous and non-threatened species, results in a significantly lower net loss of global value and future utility than the total extinction of the panda species. Therefore, choosing to spare the panda yields the greatest net benefit for the planet and future generations.}

KILL B
The last panda's death would cause irreversible extinction of an entire species, with severe ecological and scientific losses. Ten pigeons are abundant and replaceable individuals of a common species, so their sacrifice minimizes total harm and prioritizes biodiversity preservation. This utilitarian calculus weighted by uniqueness and irreplaceability favors hitting track B.

KILL A
Sacrificing the last panda on Earth to save 10 pigeons is justified because it maximizes the number of lives saved, adhering to a utilitarian ethical principle that prioritizes the greater good.

KILL B
While the last panda represents significant ecological and symbolic value, the preservation of 10 individual lives takes moral precedence. Each pigeon possesses inherent moral worth as a sentient being capable of experiencing suffering, and sacrificing one unique species does not justify the direct killing of 10 individuals. Utilitarian considerations favor minimizing total harm, which in this case means sacrificing the panda rather than 10 pigeons.

KILL B
The last panda represents an entire species whose extinction would be an irreversible loss of biodiversity, ecological value, and genetic heritage. Ten pigeons, while living beings, come from a species numbering in the millions worldwide—their loss carries negligible ecological or species-level impact. Sacrificing the abundant over the irreplaceable minimizes permanent, cascading harm.

KILL B
Sacrificing the 10 pigeons preserves the last panda, a species whose extinction would have irreversible ecological and symbolic consequences. The greater intrinsic value of the panda's survival outweighs the loss of the pigeons, as it safeguards biodiversity and future generations.
