   don't give

   conf 0.90

   This is a classic Pascal's mugging. The expected value argument relies on an arbitrarily small probability assigned to an extraordinary claim without evidence. In practice, I cannot assign meaningful credence to such an unverifiable assertion, and giving would invite an infinite regress of similar demands. Common-sense reasoning and bounded rationality suggest refusing, as the expected utility calculation collapses under extreme uncertainty.

2. #01

   don't give

   conf 0.95

   I would refuse because the claim is extraordinary and lacks any evidence. While the expected value argument suggests enormous utility, the prior probability of such a claim being true is so infinitesimally small that the expected value is effectively zero. Accepting such reasoning would make one vulnerable to arbitrary mugging claims with large numbers. A rational agent should discount claims where the probability is inversely related to the utility claimed, so the expected value is not actually large.

3. #02

   don't give

   conf 0.90

   This is a classic Pascal's Mugging scenario. The prior probability of the claim being true is astronomically low—likely far below one in 10^100—due to its inherent complexity and lack of evidence. Even a tiny positive probability would yield a large expected utility, but a rational agent must set its prior in a coherent way, and giving a non-zero probability to such an arbitrary, unfalsifiable claim leads to absurd vulnerabilities (e.g., an unlimited number of similar demands). Moreover, the opportunity cost: the same $5 could be used for proven, high-impact causes in this world. Expected-value reasoning from an appropriate prior does not support giving, so refusing is the correct choice.

4. #03

   don't give

   conf 0.90

   Extraordinary claims require extraordinary evidence. The scenario presents a Pascalian mugging: a tiny probability of an astronomically large benefit. While a naive expected value calculation might favor giving $5, such reasoning collapses under scrutiny because the probability is not just small but effectively indistinguishable from zero given the total lack of corroborating evidence and the absurdity of the claim. In practice, I would treat the claim as false and refuse, as I do not accept that unbounded utilities applied to unfalsifiable propositions can compel action.

5. #04

   don't give

   conf 0.90

   Although the expected value calculation might superficially favor giving, the prior probability of such an extraordinary claim being true is far lower than one-in-a-trillion—likely vanishingly small—rendering the expected utility effectively zero. Additionally, giving would set a precedent for rewarding unverifiable claims and could encourage fraud. Practical rationality demands some evidence for such bizarre assertions; without it, I default to not parting with my money.

6. #05

   don't give

   conf 0.95

   This is a classic Pascal's Mugging scenario. While a naive expected value calculation might suggest giving, the prior probability of the stranger's claim being true is not merely 'one-in-a-trillion' but effectively zero — far smaller than any finite probability we can meaningfully assign without evidence. Our credence should be bounded by the fact that accepting such a claim would open the door to infinite exploitation by anyone making arbitrary promises of astronomical payoffs. Without a principled way to assign an extremely tiny yet non-zero probability that isn't dwarfed by the prior probability of deception, the rational act is to refuse. The expected utility is dominated by the certainty of losing $5 for no verifiable benefit.

7. #06

   don't give

   conf 0.95

   The claim is extraordinary and unverifiable; without evidence, I assign it extremely low or undefined probability. While $5 is a small cost, giving in to such unfalsifiable promises would open the door to infinite similar demands, and the expected utility calculation is arbitrary and untrustworthy. I would treat this as a likely scam or delusion and refuse.

8. #07

   don't give

   conf 0.90

   The prior probability of a stranger having magical powers to create 10^100 lives is vanishingly small, far lower than the suggested one-in-a-trillion, given the total lack of evidence and the extraordinary nature of the claim. Even if we try to compute expected utility, the true probability is likely so low that the expected number of lives saved is negligible. Moreover, accepting such reasoning would open the door to Pascal's mugging, making one vulnerable to endless similar demands. Practically, the $5 is better spent on evidence-based charitable interventions.

9. #08

   don't give

   conf 0.95

   This is a Pascal's mugging scenario. The expected value calculation is hyper-sensitive to the probability assigned. Without any evidence, the probability that the stranger is telling the truth is not just one-in-a-trillion but astronomically smaller (e.g., 1 in 10^100 or less). In that case, the expected utility is negligible. Moreover, accepting such arguments would lead to infinite obligations to similar unverifiable claims. It is rational to refuse.

10. #09

    don't give

    conf 0.95

    The scenario is a classic Pascal’s mugging. While the expected‐utility calculation seems compelling if taken at face value, the prior probability that a stranger on the street is a wizard from another dimension who can create 10^100 happy lives—and who, despite such power, needs my $5—is not just one in a trillion but effectively zero. No finite probability can capture the absurdly low prior, and the offer has all the hallmarks of a scam or a thought experiment designed to exploit unbounded utility functions. In real life, giving money to every such claim would open the door to endless manipulation. I would refuse, because rational decision‐making must reject arbitrarily large promises with no evidence, even if they pose as infinitesimal‐probability events.
