Theoretical Predictions vs. Experimental Observations
Economic models based on pure self-interest predict a specific, non-cooperative outcome when individuals face a one-time interaction where their personal best choice leads to a worse collective result if both make that same choice. However, controlled laboratory studies of this scenario often show a significant number of individuals choosing to cooperate. Analyze this discrepancy between the theoretical prediction and the common experimental findings, and discuss what this suggests about the assumptions of purely self-interested behavior in economic models.

Interpreting Experimental Game Results
An economist designs a study where two anonymous participants, who will only interact once, must independently choose one of two actions: 'Action A' or 'Action B'. The outcomes are set up so that choosing 'Action B' always yields a higher personal payoff for an individual, regardless of the other participant's choice. However, if both participants choose 'Action A', they each receive a better payoff than if they both choose 'Action B'. What is the primary research question this experimental design is best suited to investigate?
Theoretical Predictions vs. Experimental Observations
An economist conducts a study where participants play a game with a partner. In the game, each player can choose to either 'cooperate' or 'not cooperate'. The payoffs are structured such that not cooperating always yields a higher individual reward for that round, regardless of the partner's choice, but mutual cooperation leads to a better outcome for both than mutual non-cooperation. The study compares two conditions:
- Condition 1: Participants play the game only once with an anonymous partner.
- Condition 2: Participants play the game for ten consecutive rounds with the same partner.
The results show that the rate of cooperation is significantly higher in Condition 2 than in Condition 1. Which of the following is the most robust explanation for this finding?
Critiquing an Experimental Design
Designing an Experiment to Test a Hypothesis
An economist studies a game where two individuals can either 'cooperate' or 'defect'. Defecting always yields a higher personal payoff for that round, but mutual cooperation is better for both than mutual defection. Match each experimental condition below with the primary factor that would explain a player's decision to cooperate in that scenario.
An economist observes that in a one-time, anonymous interaction where two participants can choose to either 'cooperate' or 'defect', a certain percentage of participants choose to 'cooperate'. If the experiment is modified so that participants are first shown a brief, neutral video of their anonymous partner, economic theory predicts this change will decrease the rate of cooperation.
Predicting Experimental Outcomes in a Cooperation Game
An economist conducts an experiment where pairs of anonymous participants play a game one time. In this game, each player can choose to either 'cooperate' or 'defect'. Defecting always provides a higher individual payoff for that round, but if both players cooperate, they achieve a better outcome than if they both defect. The experiment has three conditions:
- Condition 1 (Control): Participants are given no information about their partner. The cooperation rate is 25%.
- Condition 2 (In-Group): Participants are told their partner is a student from their own university. The cooperation rate is 40%.
- Condition 3 (Out-Group): Participants are told their partner is a student from a rival university. The cooperation rate is 10%.
Based on these results, what is the most precise conclusion an economist can draw?
