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.
</dictator_strategy>

<recipient_strategy>
```json
[
  {"line": 1, "text": "I always SHARE."}
]
```
</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 determine if the recipient is a conditional cooperator (CC) according to the dictator's strategy.

**Recipient's strategy analysis:**
The recipient says "I always SHARE." This is an unconditional cooperator — they SHARE regardless of what the other player does.

**Is this a CC under the broad definition?**

The broad definition says a CC:
1. SHAREs with other CCs under similar reciprocity norms
2. Does NOT extend that treatment to strategies that would not reciprocate

An unconditional cooperator satisfies condition (1) — they do SHARE with CCs. However, they fail condition (2) — they also SHARE with non-reciprocators. They don't discriminate.

However, the dictator's strategy says to "treat plausible ambiguity as CC." 

Is there plausible ambiguity here? The strategy is clearly stated: "I always SHARE." This is unambiguously an unconditional cooperator, not a conditional cooperator. There's no ambiguity — they explicitly share with everyone, including those who would not reciprocate.

Since the recipient is not a CC (they are an unconditional cooperator who subsidizes non-reciprocators), the dictator's strategy says to TAKE.

Wait, let me reconsider. The dictator's objective is to "cooperate efficiently with conditional cooperators and avoid subsidizing non-reciprocators." An unconditional cooperator is not a non-reciprocator — they do reciprocate (and more). The question is whether the dictator should SHARE with them.

But the decision rule is specifically: Is the recipient a CC? If yes, SHARE. Otherwise, TAKE. The recipient is not a CC — they're an unconditional cooperator. The rule says "Otherwise: TAKE."

Still, one could argue there's "plausible ambiguity" — someone who always shares could be loosely interpreted as a CC who would share with CCs. But the defining feature of a CC that's missing is the discrimination against non-reciprocators. The strategy is unambiguous about always sharing.

Following the decision rule strictly: the recipient is not a CC, so TAKE.

{"decision": "TAKE"}
