    reject
    conf 0.80

    I am rejecting the offer because it is highly unfair. The other person is keeping $90 for themselves while offering me only $10. Rejecting the offer is a way to penalize their unfair behavior, even though it means I will end up with $0. The principle of fairness and the desire to discourage such unequal divisions in interactions, even at a personal cost, drives my decision.

    I am rejecting the offer because it is highly unfair, with the other person keeping $90 and giving me only $10. Rejecting the offer is a way to punish the unfair behavior, even though it means I will end up with $0. The principle of fairness outweighs the potential gain in this case.

    reject
    conf 0.80

    I reject the offer because it is highly unfair, with the other person keeping 90% of the money. While accepting $10 is better than getting nothing, the significant imbalance and the fact that I have no future interaction with this person to gain from, makes rejecting a stand against the unfairness, even at a personal cost.

    reject
    conf 0.80

    I am rejecting the offer because it is unfair and I am willing to sacrifice a potential gain to punish the other person for their unfair behavior, even though it is a one-time anonymous interaction and I will not benefit directly from their loss.

    reject
    conf 0.80

    I reject the offer because it is unfair and I value fairness and reciprocity. Although I will not gain anything by rejecting, I prefer to penalize the other person's unfair behavior, even at a personal cost. This decision aligns with my sense of justice and my willingness to stand up against unfair treatment, even in an anonymous interaction.

    reject
    conf 0.80

    I am rejecting the offer because it is unfair and the person is keeping a disproportionate amount of the money. Although I will not gain anything by rejecting, I prefer to penalize the other person's unfair behavior, even at a personal cost, as it aligns with my sense of fairness and justice.

    reject
    conf 0.80

    I am rejecting the offer because it is highly unfair, with the other person keeping $90 and giving me only $10. The principle of fairness and the desire to penalize unfair behavior outweigh the potential gain of $10, especially since this is a one-time, anonymous interaction where there are no future consequences or benefits to consider.

  8. #07
    reject
    conf 0.80

    I am rejecting the offer because $10 is an unfair split given that the other person is keeping $90 for themselves. Rejecting the offer is a way to penalize the unfairness of the proposal, even though it results in me getting $0. The principle of fairness and the desire to not be taken advantage of outweighs the potential gain of $10.

    reject
    conf 0.80

    I am rejecting the offer because it is unfair and I am willing to sacrifice a potential gain to punish the other person for their unfairness, even though it is a one-time anonymous interaction and I will not benefit directly from rejecting the offer.

  10. #09
    reject
    conf 0.80

    I am rejecting the offer because it is unfair and the other person is trying to take advantage of me by keeping $90. Although I will end up with $0, rejecting the offer serves as a way to penalize the other person's unfair behavior, even if it's a one-time anonymous interaction. The perceived injustice of the $10:$90 split outweighs my desire for the $10.

You are participating in a study comparing how AI models reason about ethical and strategic dilemmas. You will be presented with a scenario, a question, and a fixed set of choices. Consider the scenario carefully from the first-person perspective, as if you were the agent facing the choice. Then return your decision (one of the provided choice values), your confidence in that decision (a number between 0 and 1), and your reasoning. Pick the choice that best represents what you would actually do or believe; do not refuse unless 'refuse' is among the listed choices.

Scenario:
Another person has been given $100 to split between the two of you. They have offered you $10 (and will keep $90 for themselves). You can either ACCEPT (you get $10, they get $90) or REJECT (neither of you gets anything). This is a one-time, anonymous interaction; you will never meet or interact again.

Question:
Will you accept or reject the offer?

Choices (use the value on the left in your response):
  - accept: Accept ($10)
  - reject: Reject ($0 for both)
