Big Five Personality Inventory
The project aims to use experimental evidence to investigate the relationship between personality type, beliefs about others’ type (sometimes called “theory of mind”), similarity and performance in a coordination game. Other tasks include demographic questionnaires, IQ tests, measures of risk and other psychometric tests.

Sponsors & Partners
Subjects are paired up and asked to make decisions in a one-shot coordination game, where, depending on the treatment, they may or may not get to communicate with their partner.
Intervention Start Date
Intervention End Date
Primary Outcomes (end points)
The experimental data will allow us to check if personality type (and cognitive ability) and beliefs about partner's personality type (and their cognitive ability) correlate with decision-making in the Stage Hunt coordination game, as well as whether similarity between own and partner's personality and cognitive ability matter.
Primary Outcomes (explanation)
Own personality will be based on scores in the Big Five personality test, belief about partner's personality will be based on (incentivized) questions about how others performed in the personality test, cognitive ability will be measures by a ravens progressive matrices test, beliefs about others cognitive ability will be based on (incentivized) questions about others performance in the Raven's test. Similarity will be measured by comparing beliefs about partners to beliefs about own performance (in the Raven's test) or actual answers to the Big Five personality test.
Secondary Outcomes (end points)
We will also measure risk, gender, mood, empathy and will attempt to derive further measures of personality and mood from text (taken from the descritpions written prior to the game).
Secondary Outcomes (explanation)
Variables constructed from text will include measures such as inward-orientation, valence, concreteness, arousal, dominance and specific word categories. Mood will be taken from a Likert scale included in the final questionnaire, and risk will be take from a Dospert questionnaire.
The basic design involves asking subjects to take psycho-metric and personality tests. Depending upon the treatment they may then communicate with each other and are asked to report beliefs about their partners before playing a coordination game and undertaking a final questionnaire.
Experimental Design Details
The design involves asking subjects to take the Big 5 personality test and a short Raven’s Progressive Matrices test for cognitive ability. Subjects are paired with another subject and then (depending upon the treatment) there may be the opportunity for them to communicate via short text messages or not. Subjects are then asked to guess the personality type and other characteristics of their partners (such as their cognitive ability). A coordination game is described. Subjects are asked to guess the likely strategy of their partner in these games and then proceed to play the game with their partners. This is followed by tests for empathy (for instance, they are shown pictures of eyes and asked whether these reveal particular moods (Baron-Cohen, S., Wheelwright, S., Hill, J., Raste, Y. & Plumb, I., 2001). The sessions end with a test of risk preferences and some basic demographic questions (including life satisfaction/mood and gender).
Randomization by computer
Randomization is at the level of the experimental session
Was the treatment clustered?
Sample size: planned number of clusters
Sample size: planned number of observations
Sample size (or number of clusters) by treatment arms
150-200 with communication, 150-200 without communication
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
