The mere fact that you think of using these kinds of heuristics as "lazy" and "acting without integrity" is itself an example of why this article creates a moralistic dichotomy that's both completely untrue and entirely unnecessary.

Don't fall for it. Laziness is a lot rarer than you may believe, even in yourself. People don't just "do bad things" very often for the sake of doing bad things, there are almost always reasons beyond the obvious.
