My preference is simply down to he act of lying increasing my cognitive load to engage with others. If I choose not to tell someone something, that's relatively easy. If I tell them something artificial, I have to maintain and harmonize that falsehood for the duration of the interaction.

Yes, I have a Blind account. In that context, I have a handle, but I resolutely refuse to knowingly say anything untrue. It's just too much work to be bothered.
