Another example that made me die a little inside when I read it was this:
As Brin notes, many would-be broadcasters come from an academic area where for decades the standard assumption has been that aliens are peaceful zero-population-growth no-nuke greens, since we all know that any other sort quickly destroy themselves. This seems to me an instructive example of how badly a supposed “deep theory” inside-view of the future can fail, relative to closest-related-track-record outside-view.
The inside-view tells me that is an idiotic assumption to make.
Agreed that this is the conflict of two inside views, not an inside view versus an outside view. You could as easily argue that most stars don’t seem to have been eaten, therefore, the outside view suggests that any aliens within radio range are environmentalists. And certainly Robin is judging one view right and the other wrong using an inside view, not an outside view.
I simply don’t see the justification for claiming the power and glory of the Outside View at all in cases like this, let alone claiming that there exists a unique obvious reference class and you have it.
It seems to me the obvious outside view of future contact is previous examples of contact. Yes uneaten stars is also an outside stat, which does (weakly) suggest aliens don’t eat stars. I certainly don’t mean to imply there is always a unique inside view.
Why isn’t the obvious outside view to draw a line showing the increased peacefulness of contacts with the increasing technological development of the parties involved, and extrapolate to super-peaceful aliens? Isn’t this more or less exactly why you argue that AIs will inevitably trade with us? Why extrapolate for AIs but not for aliens?
To be clear on this, I don’t simply distrust the advice of an obvious outside view, I think that in cases like these, people perform a selective search for a reference class that supports a foregone conclusion (and then cry “Outside View!”). This foregone conclusion is based on inside viewing in the best case; in the worst case it is based entirely on motivated cognition or wishful thinking. Thus, to cry “Outside View!” is just to conceal the potentially very flawed thinking that went into the choice of reference class.
Yes uneaten stars is also an outside stat, which does (weakly) suggest aliens don’t eat stars.
Weakly? What are your conditional probabilities that we would observe stars being eaten, given that there exist star-eating aliens (within range of our attempts at communication), and given that such aliens do not exist? Or, if you prefer, what is your likelyhood ratio?
This is an excellently put objection—putting it this way makes it clear just how strong the objection is. The likelihood ratio to me sounds like it should be more or less T/F, where for the sake of conservatism T might equal .99 and F might equal .01. If we knew for a fact that there were aliens in our radio range, wouldn’t this item of evidence wash out any priors we had about them eating stars? We don’t see the stars being eaten!

You think that it is idiotic to believe that many (not all) “broadcasters” expect that any aliens advanced enough to harm us will be peaceful?
No. The idiotic assumption is that which is described as the ‘standard’ assumption. No indirection.
