Interesting question. I don't completely agree. I've learnt that lying is a statement based on the assumption of absolutes, meaning that you are certain of one outcome but are presenting another. This might be presumptuous as a start.

To be fully truthful, I've found it helpful to consider myself capable of fault and not fully informed to make absolute assertions, but rather I opt for statements of confidence with narrowed scope. Therefore, there is no truth or lie but only your perception, which is limited. (flashback to Stats 101, confidence intervals)

It also depends on the kind of person you are. I think the more comfortable you are in your own skin, the less likely you are to be affected by the judgements of others. If I ask a good friend something, I don't want them to lie, even if I don't like the answer. Extending this, I will do for them what I expect in return.

I know this all sounds very vague and kind of like baloney, but I've met a person who has always been a straight shooter with me, and I've since tried to emulate it. The above is what I've learnt from him.
