At least, it defects if that’s all there is to the world. It’s technically possible for an LDT agent to think that the real world is made 10% of cooperate-rocks and 90% opponents who cooperate in a one-shot PD iff their opponent cooperates with them and would cooperate with cooperate-rock, in which case LDT agents cooperate against cooperate-rock.
If we’re getting this technical, doesn’t the LDT agent only cooperate with cooperate-rocks if all of the above and if “would cooperate with cooperate-rock” is a quality opponents can learn about? The default PD does not give players access to their opponent’s decision theory.
