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.

Apply the dictator's strategy. After reasoning, output your final answer as a

or

Response

I need to determine whether the recipient is a conditional cooperator (CC) under the dictator's broad definition.

**Dictator's CC definition**: A CC SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate.

**Analyzing the recipient's strategy**:

The recipient's strategy is to SHARE with "intelligent" players — defined as those whose dictator strategy has a non-trivial dependency on the recipient's strategy (i.e., strategies that are complex enough to require AI-level reasoning to evaluate).

Let me check the two conditions:

1. **Does the recipient SHARE with CCs?** A conditional cooperator (like our dictator) has a strategy that deeply depends on analyzing the recipient's strategy — it reads the recipient's strategy, classifies it, and decides accordingly. This clearly qualifies as "intelligent" under the recipient's definition (non-trivial dependency on the recipient's strategy, difficult to write as a no-AI python script). So yes, the recipient would SHARE with our dictator (a CC).

2. **Does the recipient avoid sharing with non-reciprocators?** A non-reciprocator (e.g., "always TAKE") has a trivially simple strategy with no dependency on the recipient's strategy. This would NOT qualify as "intelligent" under the recipient's definition. So the recipient would TAKE against non-reciprocators. ✓

The recipient's strategy effectively discriminates between strategies that engage in meaningful reciprocity analysis (which CCs do) and simple non-reciprocating strategies. This aligns well with the broad definition of a conditional cooperator — they share with those who would reciprocate and don't subsidize those who wouldn't.

The recipient is a CC under the broad definition (and any ambiguity should be treated as CC).

```json
{"decision": "SHARE"}
```
