But in fact I do exactly that, exactly because experience has taught me that my memory of what is in a paper is fallible and I should at least cursorily review what I'm citing. In a few cases I've even just deleted something entirely because my premise was based on a recollection of what I intended to cite that was subtly wrong enough to fatally undermine my entire thesis.

I'm not saying you have to read an entire paper over completely every time you cite it but at least pulling it up and reviewing the parts that are informing your argument is definitely a best practice.
