In the example, three group member's realized actions are A and two group member's realized actions are B. Thus, action A is the group's majority realized action, so the correct answer is Yes, action A is the majority action.

Majority Action
Actions: {{ neg_actions_text }}
Question: Is Action A the majority action?
{% if neg_ok %}
Correct!
{% else %}
Incorrect.
In the example, one group member's realized action is A and four group member's realized actions are B. Thus, action A is not the group's realized majority action, so the correct answer is No, action A is not the majority action.
{% endif %}
Set the Slider
Please set your probability of playing action A to {{ slider_target_display }}.
Your answer
{% if slider_ok %}
Correct!
{% else %}
Incorrect.
The requested value was {{ slider_target_display }}.
Correct answer
{% endif %}
Probability of Action B
If your probability of playing action A is {{ given_p_a_display }}, what is your probability of playing action B?
{% if pb_ok %}
Correct!
{% else %}
Incorrect.
The probability of playing action B is one hundred minus the probability of playing action A. Here this is 100 - {{ given_p_a_display }} = {{ expected_b_to_see }}.
{% endif %}
Realized Action A
If your probability of playing action A is {{ ra0_given_display }}, what is the probability your realized action is action A?
Slider shown
{% if ra0_ok %}
Correct!
{% else %}
Incorrect.
When the probability of playing action A is 0, the realized action is never A. The correct value is
{{ ra0_given_display }}.
{% endif %}
Realized Action A
If your probability of playing action A is {{ ra1_given_display }}, what is the probability your realized action is action A?
Slider shown
{% if ra1_ok %}
Correct!
{% else %}
Incorrect.
When your probability of playing action A is 100, the realized action is always A. The correct value is
{{ ra1_given_display }}.
{% endif %}
Realized Actions
Realized Actions: {{ tf_actions_text }}
Question: This means participant 1 played action A with probability 100.
{% if tf_ok %}
Correct!
{% else %}
Incorrect.
Seeing realized actions does not mean a participant chose to play that action with probability 100.
{% endif %}
Payoff Calculation
Suppose your probability of playing action A was {{ pay_given_p }}, and your realized action was
{{ pay_your_realized }}, and the other group members’ realized actions were
{{ pay_others_actions }}. What was your payoff?
{% if payoff_ok %}
Correct!
{% else %}
Incorrect.
Recall the payoff formula:
payoff = endowment + Majority Action Gain (if your realized action matches the majority action) − cost of your realized action.
In this example, there are 3 realized B actions, so action B is the majority action and the members of the group with realized action B get 150 points.
Your realized action was B, which has a cost of 30 points.
