My take on "Captain I don't care": It's a survival mechanism. He usually deals with shady types. He has no interest in whatever it is they are doing. Therefore, the weird, little clanks are none of his business. A variation on Sgt. Schultz' "I see nothing! Nothing!"
Or he lost everything/one he cared about. Or it's a result of mind control (he notices things, then standing order "don't care..." catches up with him).
