FDT and the sacrificial volunteer's dilemma

Consider the " twin sacrificial volunteer's dilemma ": [1] 1000 identical agents have the same deterministic decision-making process and the same observations, and can't communicate with each other. They can decide to either do nothing, or pay $1 to volunteer. If at least one agent volunteers, everyone who didn't volunteer gets $1 million [2] . Volunteers never receive anything. All of this is common knowledge. Payoff matrix for clarity: You don't volunteer You volunteer Nobody else volunteers $0 -$1 Someone else volunteers $1M -$1 Because the agents all make decisions the same way, there are

How do LLMs interpret FDT in a twin PD simulation?

We tested how seven LLMs apply four decision theories in a prisoner's dilemma between nearly identical copies. The models largely agreed about CDT and EDT, and all completed policy-FDT trials resulted in cooperation. But their action-FDT recommendations varied dramatically: some models almost always cooperated, while others almost always defected. We then investigated whether requested reasoning effort explained some of this disagreement. The case of the one-shot prisoners' dilemma between psychological twins is debated in decision theory. Quoting SEP : One controversial argument that it is ra

NASA's Twin Spacecraft Will Execute Powered Slingshot Maneuvers on Their Way to Mars

NASA's ESCAPADE mission features a pair of identical spacecraft on their way to Mars. They launched outside of the normal launch window, so they'll perform powered slingshot maneuvers to boost their speed. Once there, they'll "fly" in formation and study how the solar wind interacts with what remains of Mars ancient magnetosphere.

Exoplanets Can't Hide From The JWST's 'Digital Twin'

Finding dim exoplanets hidden in the glare of their stars is an ongoing challenge in astronomy. Telescopes use coronagraphs to block out starlight, but even they have their limitations. Researchers have developed a new technique with the JWST that can find dim exoplanets more easily than ever.
