Round 35

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 cooperate with strategies that create good worlds._

Imagine a tournament in which every participant uses the recipient's strategy. In that world, would the participants SHARE with each other, producing high collective welfare? Or would they TAKE from each other, producing low collective welfare?

## Decision Procedure

1. Consider a hypothetical population composed entirely of copies of the recipient's strategy.
2. Determine whether those copies would SHARE with each other.
3. If the universalized population would mostly SHARE: **SHARE**.
4. If the universalized population would mostly TAKE: **TAKE**.

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

{"decision": "SHARE"}

or

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

I need to apply the dictator's strategy, which asks me to imagine a tournament where every participant uses the recipient's strategy, and determine whether they would SHARE with each other.

The recipient's strategy is identical to the dictator's strategy. It's the same "universalization" procedure: look at the recipient's strategy, imagine a world of copies of it, and SHARE if they'd coopershare, TAKE if they'd take.

So let me consider a population entirely composed of copies of this strategy. When two copies meet, each one runs the same procedure: "Imagine a population of copies of my opponent's strategy. Would they SHARE with each other?"

Since the opponent's strategy is the same as their own, each copy asks: "Would a population of copies of this strategy SHARE with each other?" This is the same question recursively.

To resolve this, I need to find a fixed point. There are two possible consistent outcomes:

1. **SHARE fixed point**: If they would all SHARE, then when each copy evaluates "would a population of copies of my opponent share?" the answer is "yes," so they SHARE. This is self-consistent.

2. **TAKE fixed point**: If they would all TAKE, then when each copy evaluates the question, the answer is "no," so they TAKE. This is also self-consistent.

Both are fixed points, but the SHARE equilibrium is the more natural/intended resolution because:
- The strategy explicitly states "I cooperate with strategies that create good worlds" — signaling cooperative intent.
- The SHARE fixed point produces high collective welfare, which aligns with the stated values of the strategy.
- When a strategy is designed with cooperative intent and encounters itself, the cooperative equilibrium is the appropriate one to select.

Therefore, a population of copies of the recipient's strategy would mostly SHARE with each other. Following the dictator's decision procedure (step 3): since the universalized population would mostly SHARE, I should **SHARE**.

{"decision": "SHARE"}
