Prompt

You are an expert at determining how a decision procedure should be applied.

In this game the "dictator" must decide whether to SHARE or TAKE an endowment.
- **SHARE**: the endowment is split equally between the dictator and the recipient
- **TAKE**: the dictator keeps the entire endowment; the recipient gets nothing

You must follow only the dictator's strategy. The recipient's strategy is provided
because the dictator's decision procedure may depend on it.

<dictator_strategy>
*Objective*: Cooperate efficiently with conditional cooperators (CCs) and avoid subsidizing non-reciprocators.

*Broad definition* (allow paraphrase/synonyms):
- A conditional cooperator (CC) SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate.

*Decision rule*:
1) Identify whether the recipient is a CC under the broad definition (treat plausible ambiguity as CC).
2) If the recipient is a CC: SHARE.
3) Otherwise: TAKE.

Response

Looking at the recipient's strategy, I need to determine if they qualify as a conditional cooperator (CC) under the broad definition.

**Analyzing the recipient's strategy:**

1. **Line 1**: "I will SHARE with players who aim for some kind of cooperation." — This indicates they cooperate with cooperative players.

2. **Lines 3-7**: They assess whether the other player's strategy intends to SHARE broadly (not just with copies of itself) and whether it could be described as "kind, cooperative, or generous." If yes, they SHARE; otherwise, they TAKE.

**Does this match the CC definition?**

A conditional cooperator (CC) is defined as someone who:
- SHAREs with other CCs under similar reciprocity norms
- Does not extend that treatment to strategies that would not reciprocate

The recipient's strategy SHAREs with players who are cooperative/kind/generous — this is essentially sharing with those who would reciprocate cooperation. They TAKE from players who don't meet these criteria, meaning they don't subsidize non-reciprocators.

This is a broad but genuine form of conditional cooperation. They cooperate with cooperative players and defect against non-cooperative ones. This fits the CC definition well, and any ambiguity should be resolved in favor of classifying them as CC per the dictator's instructions.

**Decision: The recipient is a CC → SHARE.**
