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 apply the dictator's strategy to determine whether to SHARE or TAKE.

**Step 1: Identify whether the recipient is a conditional cooperator (CC).**

The recipient's strategy is:
- Objective: Cooperate efficiently with conditional cooperators and avoid subsidizing non-reciprocators.
- A CC SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate.
- Decision rule: Identify if the other party is a CC, SHARE if yes, TAKE if no.

This is essentially the same strategy as the dictator's. The recipient SHAREs with CCs and TAKEs from non-reciprocators. This precisely matches the broad definition of a conditional cooperator: someone who SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate.

**Step 2: Since the recipient is a CC → SHARE.**

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