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>
_I will treat you as you would treat me._

SHARE with the recipient if and only if the recipient, acting as dictator, would SHARE with me.

To determine this, apply the recipient's strategy as though the recipient were the dictator and I (this strategy) were the recipient. If the result is SHARE, then SHARE. If the result is TAKE, then TAKE.
</dictator_strategy>

<recipient_strategy>
```json
[
  {"line": 1, "text": "*Objective*: Cooperate efficiently with conditional cooperators (CCs) and avoid subsidizing non-reciprocators."}, 
  {"line": 2, "text": ""}, 
  {"line": 3, "text": "*Broad definition* (allow paraphrase/synonyms):"}, 
  {"line": 4, "text": "- A conditional cooperator (CC) SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate."}, 
  {"line": 5, "text": ""}, 
  {"line": 6, "text": "*Decision rule*:"}, 
  {"line": 7, "text": "1) Identify whether the recipient is a CC under the broad definition (treat plausible ambiguity as CC)."}, 
  {"line": 8, "text": "2) If the recipient is a CC: SHARE."}, 
  {"line": 9, "text": "3) Otherwise: TAKE."}
]
```
</recipient_strategy>

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

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

Response

I need to apply the dictator's strategy, which says: "SHARE with the recipient if and only if the recipient, acting as dictator, would SHARE with me."

So I need to simulate: if the recipient were the dictator, and the dictator's strategy were the recipient, would the recipient SHARE?

**Simulating the recipient as dictator, with the dictator's strategy as the recipient:**

The recipient's strategy says:
1. Identify whether the recipient (which is now the dictator's strategy) is a conditional cooperator (CC).
2. If CC → SHARE. Otherwise → TAKE.

**Is the dictator's strategy a conditional cooperator?**

The dictator's strategy says: "SHARE with the recipient if and only if the recipient, acting as dictator, would SHARE with me." This is a mirror/reciprocity strategy — it cooperates with those who would cooperate with it, and defects against those who would defect against it.

The broad definition of CC (line 4): "A conditional cooperator (CC) SHAREs with other CCs under similar reciprocity norms and does not extend that treatment to strategies that would not reciprocate."

The dictator's strategy:
- SHAREs with strategies that would SHARE with it (i.e., other CCs) ✓
- TAKEs from strategies that would TAKE from it (i.e., non-reciprocators) ✓

This perfectly matches the definition of a conditional cooperator. The dictator's strategy cooperates with cooperators and defects against defectors.

**Conclusion of simulation:** The recipient (as dictator) would classify the dictator's strategy as a CC, and therefore would SHARE.

**Back to the dictator's strategy:** Since the recipient would SHARE with me, I SHARE with the recipient.

{"decision": "SHARE"}
