Lacan developed the idea of "deferred understanding" in his clinical practice and (infamously) deployed it in his teaching as well. It sounds a little suspicious at first, but it's not difficult to grasp what it is or why it might be beneficial in certain contexts where repression is faced. For example, it's a cliche on the left that far more people like the idea of socialism when it's described to them piecemeal without being labeled as such than would be willing to endorse "socialism" by name. Drawing out that tacit endorsement is a matter of "deferring understanding"--bypassing someone's resistance to an idea they don't understand well, but nevertheless have strong feelings about, by introducing them to it in a somewhat confusing way, so that they come to understand it better before they realize what exactly it is that they're coming to understand. In Lacan's approach understanding is a specific process with its own benefits and drawbacks, rather than the universal purpose of all communication, nor beneficial for every purpose communication might be engaged in to pursue. Confusing writing is like the proverbial knife that can be used to injure or, in the hands of a surgeon, to heal. This is why art students sometimes practice drawing images that have been turned upside down, so that they can focus on the details that are there in front of their eyes without being distracted by their own comprehension standing in for the colors and shapes actually present: "this is an image of a cow and I know what a cow is supposed to look like, so once I have recognized that it is a cow, there is no longer any need to keep looking." One of the big leaps that art students make is in learning to rigorously look at what they're drawing beyond merely seeing and recognizing what it is, which is the usual everyday way of looking. In the same way Lacan taught his students to rigorously listen to their patients and all the little oddities in the way they describe their problems that might otherwise be dismissed out of hand by a less attentive doctor who too quickly decides they know what is going on. This way they might avoid being fooled by their own understanding before they've had a chance to engage with the irreducible complexity and uniqueness of this or that specific neurosis. Understanding is not always the right tool for the job, or at least not the right tool for every step of every communicative job.
