True. Assume agent A$1$ is a logical agent and agent A$2$ is an irrational agent. There is a task environment where A$2$ will actually perform better than A$1$ because A$2\text{'}$s illogical decisions may produce better results than A$1\text{'}$s reasonable ones. For instance, A$2\text{'}$s irrational decision to always choose rock in the game of rock$-$paper$-$scissors may be more successful than A$1\text{'}$s rational decision to select the option with the highest likelihood of success.
