Let's see if we can break some of these down into categories of deception to extract some principles. Ultimately I guess we lie and deceive because we believe it will benefit us. It will avoid conflict; it will keep people from harming me; it will prejudice people in my favor etc. So then I think the question we have to ask is; is the benefit to be gained by deception worth the harm that it does?
So what is the deception protecting? I think our general social consensus is that deception to protect someone's life is permissible and excuseable. And deception to protect your property from harm is also permissible. People vary on how permissible deception as a social lubricant is, but many a wise man has learned to be a little bit circumspect when his wife asks if something makes her look fat. In the wife hiding receipts example this gets a little more confusing because the deception protects not only the wife's physical safety, but also any bad financial habits she has and the whole extremely unhealthy dynamic of that relationship. So I won't tell her, yeah be perfectly honest with him because that's the right thing to do even if it results in him abusing you, but the deception definitely isn't a good or healthy or really even acceptable thing in this case. It's a huge mess.
The flip side then is what harm does the deception do? An extra dollar on my electricity bill as a kind of burglar insurance and a burglar not getting to burgle stuff from me is a pretty minimal harm. As is just about any impact on someone of the difference makeup will make to my appearance ( I was going to just say appearance, but there's too much that can be said about appearances and the deception of pornography and intentionally inciting to lust to just categorically say appearance causes negligible harm in all cases).
Something should also be said about the frequency of use of deception because deception erodes trust and without trust we end up with the breakdown of just about any unity or co-operation between people. Kind of like the boy who cried wolf if we use deception too often in too many petty matters, then we destroy ourselves (after all if you lied about A when the stakes seemed so low, why should anyone think you'd tell the truth when it mattered?).
Ok that's my first round of thoughts. Good on you for starting this discussion.
