I think Laziness is probably correlated to being an introtim. I'm a pretty strong introtim and I'm lazy.
Reasoning in means, enneatypes 4-5-9 ("withdrawn group") are the least motivated. But in this enneatype group only 10-20% are extrotims. in socioniko.net I read that initiative is correlated with being an extrotim. If 459 is correlated to being an introtim and tending to lack initiative is correlated to being an introtim, then 459 + lack of initiative is probably correlated to laziness.
