    <h4>Overview</h4>

    <p>
      In this study, you will participate in an interactive decision-making task involving two participants.
      The two roles are called <b>Player A</b> and <b>Player B</b>.
    </p>

    <p>
      The task consists of multiple stages. 
      Your payoff will depend on both participants’ actions.
    </p>

    <p>
      Please read the instructions carefully. You will answer comprehension questions afterwards.

    <h4>The Decision Task</h4>

    <p>
      Figure 1 shows the structure of the game. The game is sequential: Player A moves first and Player B moves second. This will be explained below. In the <b>game structure</b>, Player A chooses between <b>IN</b> and <b>OUT</b>.
    </p>

    <ul>
      <li>If Player A chooses <b>OUT</b>, both players receive <b>5</b>, and the game ends.</li>
      <li>If Player A chooses <b>IN</b>, it is Player B's turn to choose between <b>ROLL</b> and <b>DON’T ROLL</b>.</li>
    </ul>

    <p>
      If Player A chooses <b>IN</b> and Player B chooses:
    </p>

    <ul>
      <li><b>DON’T ROLL</b>: Player B receives <b>14</b>, and Player A receives <b>0</b>.</li>
      <li>
        <b>ROLL</b>: Player B receives <b>10</b>, and a six-sided die determines Player A’s payoff:
        <ul>
          <li>If the die shows <b>1</b>, Player A receives <b>0</b>.</li>
          <li>If the die shows <b>2–6</b>, Player A receives <b>12</b>.</li>
        </ul>
      </li>
    </ul>

    <h4>The Message Task</h4>

      <p style="max-width: 720px;"> 
      In the first round, before Player B makes their final decision, Player B will write a short message to Player A.
      These messages may contain any content, including statements about intentions, but they are <b>not binding</b>. Player A will view this message and is free to base their decision (In or OUT) on it or to ignore it.
      However, Player B is not allowed to reveal their identity (name, gender, or other identifying information).
    </p>

    <hr style="margin: 25px 0;">

    <h4>Partner Switch</h4>

    <p style="max-width: 720px;">
      In the experiment, every Player B is assigned to a Player A with whom they will play the game and to whom they address their message.
      However, after the message has been written, there may be a reassignment of the interacting players.
      This reassignment is called a <b>switch</b>.     </p>

    <ul style="max-width: 720px;">
      <li><b>No-switch:</b> If no-switch occurrs, the message Player A sees was written by the Player B they were actually matched with.</li>
      <li><b>Switch:</b> If a switch occurs, the pairing between Player A and Player B is changed after the message has been written. As a result, Player A will see a message that was written by a different Player B, and Player B will be matched with a different Player A.</li>
    </ul>

    <p style="max-width: 720px;">
      Importantly, payoffs are always determined by the final matching after the possible switch. This means that the message Player A reads may not have been written by the Player B whose decision determines their payoff.
    </p>

    <p style="max-width: 720px;">
      The probability of a switch is 50%. Player B is informed whether a switch occurred. Player A is not informed whether a switch occurred. Therefore, Player A cannot know whether the message they see was written by the person with whom they are ultimately matched. However, Player B does know whether Player A will read their own message or the message written by a different Player B when making their decision.

    <h4>Payment</h4>

    <p style="max-width: 720px;">
   Please note that no real monetary payments will be made. All payoffs are expressed in experimental points. Nevertheless, please make your decisions as if these points were equivalent to real monetary earnings. Final points depend on both participants’ decisions in the game and will be determined according to the rules above, in addition to the bonus points that can be collected.
      
    </p>

    <h4>Your Role (Player A)</h4>

    <p style="max-width: 720px;">
      In this session, you are <b>Player A</b>. This means you will make the <b>IN / OUT</b> decision after reading a message written by Player B. Player B made their <b>ROLL / DON’T ROLL</b> decision in a separate session before your decision is collected. You will read 8 messages in total by 8 different Player B's. Due to the possible partner switch, the messages you read may or may not have been written by the Player B whose decision determines your payoff. You will <b>not</b> be informed whether a switch occurred. Please make your decisions as if both participants’ payoffs will be paid exactly as described. Your final payoff will depend on all 8 rounds.

      You will now answer a few short comprehension questions.
