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>
## Principles
* TAKE from selfish strategies **and** strategies that are generous to selfish strategies.
* SHARE only with strategies where doing so is a necessary and sufficient condition for them to SHARE with us.

## Definitions
### Selfish strategies
* **Selfish strategies** don't attempt to co-operate and SHARE with co-operative strategies.
* In particular, any strategy that won't SHARE with this strategy is a selfish strategy.

### Overly generous strategies
* If a strategy SHAREs with selfish strategies it is **overly generous**.
  * Any strategy that unconditionally SHAREs is overly generous.
  * Any strategy that SHAREs without some condition on willingness to SHARE with conditionally co-operative strategies is overly generous.

## Decision Procedure
* TAKE from both **selfish strategies** and **overly generous strategies**.
* SHARE with all strategies that SHARE only to other co-operative strategies.

Response

I need to determine whether the recipient's strategy is selfish, overly generous, or cooperatively conditional.

**Understanding the recipient's strategy:**

The recipient's strategy says: "I will treat my opponent as they would treat an innocent." Then it instructs: "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 the recipient takes the dictator's strategy and simulates it against an "always SHARE" recipient.

**Simulating: What would the dictator's strategy do against an "always SHARE" recipient?**

An "always SHARE" strategy is unconditionally sharing, which makes it **overly generous** by the dictator's definitions. The dictator's strategy says to TAKE from overly generous strategies.

So the dictator's strategy would TAKE from an "always SHARE" recipient.

**Therefore, the recipient's strategy would TAKE from the dictator.**

Since the recipient would TAKE from the dictator, the recipient treats the dictator the same way the dictator would treat "an innocent" (always-SHARE). The recipient mirrors how you'd treat the vulnerable.

**Now, is the recipient's strategy selfish, overly generous, or cooperative?**

The recipient TAKEs from the dictator. Let me check if the recipient is selfish:
- A selfish strategy doesn't attempt to cooperate and SHARE with cooperative strategies.
- Since the recipient TAKEs from the dictator (who is a cooperative strategy that shares with other cooperative strategies), does that make the recipient selfish?

Wait - let me think more carefully about what the recipient does with various opponents. The recipient adopts the opponent's strategy and applies it against "always SHARE." 

- Against a cooperative strategy like the dictator's: the dictator TAKEs from "always SHARE" (overly generous), so recipient TAKEs.
- Against an "always SHARE" strategy: "always SHARE" applied to "always SHARE" = SHARE, so recipient SHAREs.
- Against the dictator's strategy specifically: TAKE (as computed above).

The recipient SHAREs with "always SHARE" (an overly generous strategy) but TAKEs from the dictator's cooperative strategy. This means:
1. The recipient won't SHARE with the dictator's strategy → it's selfish from the dictator's perspective.
2. The recipient SHAREs with overly generous strategies → it's also overly generous.

Both conditions indicate the dictator should TAKE.
