Something that's been really invaluable to me, as a Windows user, is
this little tool somebody developed. (Is it okay to link to this?) (Ed: Nope! ) It's really helped me find the range in the terms without having to buy a whole new computer.
One of my favourite concerns to do this for is Memory because it has (in my mind) a whole lot of inherent flexibility. For example, problems of Memory can mean: refusing to let go of a positive memory (implying loss, nostalgia, 'golden age thinking'); compulsively remembering something negative (regret, guilt, trauma); misremembering or forgetting something crucial (various memory biases, amnesia, dementia); recreating something from memory (like a painting, or an ancient politician); wanting to be forgotten; memorializing somebody controversial; attempting to erase someone from public memory (damnatio memoriae)...on and on and on.
You can see, hopefully, how this method can be applied to Understanding. Invert, twist, add qualifiers, moral judgements, and specificity. Is the (Not/Mis)Understanding intentional? Desirable? Are the ends beneficial or destructive? What are they attempting to understand?
After you've got that down, you just have to remember that each story point is independent of the others, to be encoded however many different ways you'd like.
