Overview

Part 2 consists of 80 periods. In every period, you will be presented with a situation in which you will make two decisions, named the CHOICE and the ESTIMATE.

In every decision, you can earn points. At the end of the experiment, the computer will randomly select one of the 80 periods. Additionally, the computer will randomly select either the CHOICE or the ESTIMATE. Your earnings in Part 2 will be determined by the number of points you earned in the selected decision of the selected period. The number of points you earned in this decision will be converted to Euro using the following exchange rate:

1 Point = 1 Euro

We will now explain the situations with which you will be presented and the decisions you will make in more detail.

Situations

In every situation, you will interact with two randomly selected other participants from today's experiment, one in the CHOICE and one in the ESTIMATE. We will refer to the participant with whom you will interact in the CHOICE as CHOICE-other and to the participant with whom you will interact in the ESTIMATE as ESTIMATE-other.

Important: CHOICE-other and ESTIMATE-other are different randomly selected participants from today's experiment.

Figure 1 depicts an example situation. At the top of this example situation, you can see the text "You: Same Label". In other situations, you may see the text "You: Different Label". In the middle of the example situation, you can see two boxes that contain labels. In the example situation, these labels are faces. In other situations, you may see other labels. Finally, at the bottom of the example situation, you can see the text "Other: Different Label". In other situations, you may see the text "Other: Same Label".

Important: In the texts "Other: Same Label" and "Other: Different Label", "Other" refers to both CHOICE-other and ESTIMATE-other.

You: Same Label



Other: Different Label

Figure 1: Example Situation

Important: CHOICE-other and ESTIMATE-other will see the exact same labels as you. However, the positions of the labels (left, right) on their computer screen may be different from the positions of the labels on your computer screen.

The CHOICE

Recall that in the CHOICE, you will interact with one randomly selected other participant from today’s experiment, to whom we refer as CHOICE-other. In the CHOICE, both you and CHOICE-other choose one of the labels, without knowing each other's choice.

In the CHOICE, you can earn either 0 points or 15 points. If the text "You: Same Label" is shown at the top of the situation, you earn 15 points if you choose the same label as CHOICE-other and 0 points if you choose a different label than CHOICE-other. If the text "You: Different Label" is shown at the top of the situation, you earn 15 points if you choose a different label than CHOICE-other and 0 points if you choose the same label as CHOICE-other.

Similarly, if the text "Other: Same Label" is shown at the bottom of the situation, CHOICE-other earns 15 points if he or she chooses the same label as you and 0 points if he or she chooses a different label than you. If the text "Other: Different Label" is shown at the bottom of the situation, CHOICE-other earns 15 points if he or she chooses a different label than you and 0 points if he or she chooses the same label as you.

Figure 2 depicts the CHOICE. Select "Left Label" to choose the label that is shown on the left box and select "Right Label" to choose the label that is shown on the right box. You will learn which label was chosen by CHOICE-other only at the end of the experiment.

The ESTIMATE

Recall that in the ESTIMATE, you will interact with a different randomly selected other participant from today’s experiment, to whom we refer as ESTIMATE-other. In the ESTIMATE, you report your best estimate of the probabilities with which ESTIMATE-other chooses each of the two labels in his or her own CHOICE. Importantly, ESTIMATE-other faces the exact same payoff consequences as CHOICE-other.

For example, you may believe that it is very likely that ESTIMATE-other chooses the label that is shown on the left box. In that case, you could, for example, report a probability of 88% that ESTIMATE-other chooses the label that is shown on the left box. Similarly, you may believe that it is somewhat likely that ESTIMATE-other chooses the label that is shown on the right box. In that case, you could, for example, report a probability of 56% that ESTIMATE-other chooses the label that is shown on the right box.

In the ESTIMATE, you can earn either 0 points or 15 points. Your chance of earning 15 points depends on the accuracy of your estimate. The accuracy of your estimate will be determined using the so-called binarized scoring rule. This rule is based on a mathematical formula that has the following properties:

It is not important for you to understand the mathematics behind the rule, as long as in every period, you base your estimate on the two properties listed above. Those interested in the formula and a mathematical proof of the properties can contact the experimenter after the experiment.

Figure 3 depicts the ESTIMATE. You can report your estimate by clicking on a slider that ranges from "Left Label" to "Right Label". Every time you click on the slider, two numbers will appear. The number below "Left Label" refers to the probability with which you believe ESTIMATE-other chooses the label that is shown on the left box, and the number below "Right Label" refers to the probability with which you believe ESTIMATE-other chooses the label that is shown on the right box. You will learn which label was chosen by ESTIMATE-other only at the end of the experiment.

Additional Instructions
{% if player.order == 1 %}

In every period, you have to choose which decision, the CHOICE or the ESTIMATE, you complete first. After you have completed the first decision, you will automatically continue to the other decision.

{% endif %} {% if player.order == 2 %}

In every period, you have to complete the CHOICE first. After you have completed the CHOICE, you will automatically continue to the ESTIMATE.

{% endif %} {% if player.time_pressure == 1 %}

In every period, the total amount of time you are allowed to spend on the CHOICE and the ESTIMATE is at most 15 seconds. For this reason, a timer counting upwards from 00:00 will be displayed at the top of the computer screen during Part 2. If you complete one or both decisions after the timer has reached 00:15, your earnings in both decisions will automatically be equal to 0 points.

{% endif %} {% if player.time_pressure == 2 %}

In every period, the total amount of time you need to spend on the CHOICE and the ESTIMATE is at least 15 seconds. For this reason, a timer counting upwards from 00:00 will be displayed at the top of the computer screen during Part 2. If you complete both decisions before the timer has reached 00:15, your earnings in both decisions will automatically be equal to 0 points.

{% endif %}

Important: When you make your decisions, you do not know which period and which decision will be randomly selected to determine your earnings in Part 2. As every decision in every period is equally likely to be relevant for your earnings, you should consider every decision in every period to be equally important and make your decisions accordingly!
