I read an interesting explanation for how lying developed in humans: when we became capable social creatures, lying to others would be a quick way of gaining an advantage, so it would be selected for in the individual. However, a culture made up of liars would be less trusting of each other, and so at a disadvantage. In this way, we evolved to give off signals, and feel guilt, when we are lying. However, it remained useful to lie to others, and so we evolved to be able to still do so. If we first lie to ourselves, trick ourselves into believing a falsehood is true, we can then spread this to others as if it were true, and therefore without consequences. In historical societies, it seems this was the right balance between generally telling the truth to others, while still being able to lie when it is important to do so. I wonder if it is time for the balance to swing the other way again, and for lying to again be selected against.
