    Now we are getting into confused territory. There is a difference between
    knowing the truth and being truthful. It may be a bad idea to tell your
    girlfriend that she is average (LOL!) on your girlfriend-o-meter, but it's
    probably better to know that you really feel that way yourself.

    It seems to be perfectly rational, in a social context, to lie; in fact,
    many people do it most of the time, rationally. As to whether it is rational
    to actually believe a lie, I can't think of a single situation. Well, maybe
    if there is a rational action that you need to take... say you need to cut
    off your own arm to escape an accident, and you find that you need to pray
    to a god to "find the strength" to do it, then it's probably rational to
    adopt the false belief (assuming you find that possible).

    A separate situation to consider is whether it is ever rational to not seek
    the truth, knowing that you don't currently possess it. I'd say this is an
    unqualified yes. It is always the case that we have incomplete information,
    some of which must be incorrect. Yet to act, we must have made a judgement
    that further truth seeking is not worth the cost. It is plausible that the
    amount of truth to find may in fact be infinite, which is a proof in itself
    that it is rational to not seek the whole truth.
