"So if something is an ideology it comes about because of a false consciouness."
or mental lazyness
"Does that make all ideologies bad?"
Maybe "bad" is the wrong word; how about "counter productive"?
"What does a true consciousness produce?"
Awareness? Action that is not merely a reaction?
"And can an individual ever know all the forces that impel her to do something? Can a person achieve that level of transparency?"
Not once and for all, since the world keeps changing. Self-reflection doesn't ever stop -- except when you die, literally or figuratively.
