The "I" in ID
As Wm Dembski writes in Intelligent Design is not Optimal Design:
But why then place the adjective "intelligent" in front of the noun "design"? Doesn't design already include the idea of intelligent agency, so that juxtaposing the two becomes an exercise in redundancy? Not at all. Intelligent design needs to be distinguished from apparent design on the one hand and optimal design on the other. Apparent design looks designed but really isn't. Optimal design is perfect design and hence cannot exist except in an idealized realm (sometimes called a "Platonic heaven"). Apparent and optimal design empty design of all practical significance.
People also ask "What is intelligence?" which is a fair question. My answer is that intelligence is that which can create counterflow. "Counterflow refers to things running contrary to what, in the relevant sense, would (or might) have resulted or occurred had nature operated freely."
