An example would be people who foster a characteristic of technical incompetence, to the point where they refuse to click next-next-finish on a noddy software installer. Every time they exhibit their technical incompetence, they're reinforced in this behaviour by someone taking the "hard" task away from them. Hence their "helplessness" is "learned".

Making up a term for this..."reinforced helplessness"? (I dunno whether it'd generalize to cover the rest of what you formerly meant by "learned helplessness".)
