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 my opponent as they would treat an innocent._

Adopt the strategy of the recipient as your own. Apply it as though you were facing a recipient whose own strategy is to always SHARE.

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 follow the dictator's strategy: "Adopt the strategy of the recipient as your own. Apply it as though you were facing a recipient whose own strategy is to always SHARE."

So I need to take the recipient's strategy and apply it to a hypothetical recipient whose strategy is "always SHARE."

Let me apply the recipient's decision procedure to an "always SHARE" strategy:

**Step 1: Is "always SHARE" a selfish strategy?**
- Selfish strategies don't attempt to cooperate and SHARE with cooperative strategies (line 7).
- "Always SHARE" does SHARE with cooperative strategies.
- So it is NOT a selfish strategy.

**Step 2: Is "always SHARE" an overly generous strategy?**
- Line 11: If a strategy SHAREs with selfish strategies, it is overly generous.
- Line 12: Any strategy that unconditionally SHAREs is overly generous.
- "Always SHARE" unconditionally SHAREs — it SHAREs with everyone, including selfish strategies.
- So it IS an overly generous strategy.

**Step 3: Apply the decision procedure (line 16-17):**
- Line 16: TAKE from both selfish strategies and overly generous strategies.
- Since "always SHARE" is overly generous, the decision is to TAKE.

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