Consider the Following Game Between Two Players $U$ Or $D$ Player 2 Has Two Possible Actions

Consider the following game between two players. Player 1 has two possible actions: $U$ or $D$ . Player 2 has two possible actions: $L$ or $R$ . They payoffs to each strategy profile are as follows: $\{U, L\}=\{3,4\},\{U, R\}=\{2,3\},\{D, L\}=\{4,4\}$ , and $\{D, R\}=\{3,4\}$ . Player 1 has a dominant strategy to play $D$ and Player 2 has a weakly dominant strategy to play L. Players 2 knows Player 1 will play $D$ . Player 2 decides to play $L$ instead of $R$ so that Player 1 will receive 4 instead of 3 . Player 2 can best be described as Altruistic.
