Honestly, I find it both empowering (oh the data I can find if I know where to look) and reassuring. Why reassuring? Because it reminds us that lies can and will be discovered. Some people like to think they'll get away with one but it's only a function of how much someone else cares. But reality is self-consistent and in the Great Web of Causality falsehood is just damage that needs to be routed over.

Conversely, lying is a malicious act. It'sdirectly sabotaging the model of the world and reasoning capabilities of other human beings, with recursive damage being dealt as that person propagates or reasons from false information. Unless placed in life or death situation (std::jews_hiding_in_your_basement), you really shouldn't do it. It boggles my mind how lightly people treat spreading falsehoods.
