Interventions

Intervention(s)
This lab study will investigate the relationship between intelligence and strategic sophistication.
Intervention (Hidden)
This lab study will investigate the relationship between practical intelligence and strategic sophistication. To measures practical intelligence we will use scores from an 11-question test of situational judgment derived from ICAR (International Cognitive Ability Resource). We will control for fluid intelligence using an 11-question matrix reasoning test from ICAR. To measure strategic sophistication we will use choices in the p-beauty contest game. Subjects will play a p-beauty contest game in fixed groups of three with p=0.7 for up to 10 rounds. Each group will play five rounds for sure, after which there will be a continuation probability (90%, 75% or 50%) at the end of each round, with a maximum of ten rounds. Our primary interest is to measure how scores on the situational judgment test predict choices in the p-beauty contest game.

Randomization Method
Subjects will be randomized into fixed groups of three by the computer. The continuation probability will be fixed at the session level.

Experiment Characteristics

Sample size: planned number of clusters
With 144 subjects, we will have 144 clusters in the first round, before subjects get feedback about others' choices.
144 / 3 = 48 clusters in later rounds to account for non-independence within fixed groups of three after the first round.
Sample size: planned number of observations
144 subjects, each making a choice for up to ten rounds. The number of rounds, and hence the number of observations, will be determined randomly since the design includes a continuation probability.
Sample size (or number of clusters) by treatment arms
144 subjects, split equally among the three continuation probabilities. We aim to run 12 sessions of 12 subjects. Depending on turnout, each session might have slightly more or slightly fewer subjects.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
