Disagree. Most people use "unlikely" for something that fits their model but is unlikely, e.g., winning the lottery, having black come up ten times in a row in a game of roulette, two bullets colliding in mid air. "Untrue" is used for something that one's model says is impossible, e.g, Zeus or ghosts existing.
I am confused now. Did you properly read my post? What you say here is 'I disagree, what you said is correct.'
To try and restate myself, most people use 'unlikely' like you said, but some, many of whom frequent this site, use it for 'so unlikely it is as good as impossible', and this difference can cause communication issues.
My point is that in common usage (in other words from the inside) they distinction between "unlikely" and "impossible" doesn't correspond to any probability. In fact there are "unlikely" events that have a lower probability than some "impossible" events.
Assuming you mean that things you believe are merely 'unlikely' can actually, more objectively, be less likely than things you believe are outright 'impossible', then I agree.
What I mean is that the conjunction of possible events will be perceived as unlikely, even if enough events are conjoined together to put the probability below what the threshold for "impossible" should be.
True. However, there is no such thing as 'impossible', or probability 0. And while in common language people do use 'impossible' for what is merely 'very improbable', there's no accepted, specific threshold there. Your earlier point about people seeing a fake distinction between things that seem possible but unlikely in their model and things that seem impossible in their model contributes to that. I prefer to use 'very improbable' for things that are very improbable, and 'unlikely' for things that are merely unlikely, but it is important to keep in mind that most people do not use the same words I do and to communicate accurately I need to remember that.
Okay, I just typed that and then I went back and looked and it seems that we've talked a circle, which is a good indication that there is no disagreement in this conversation. I think that I'll leave it here, unless you believe otherwise.
