You, on the other hand, while asserting that the prosecution’s arguments collectively deserve high weight
You are talking about the evidence, right?
In response to requests for a defense of such, you’ve told me it’s not your job to do my homework.
In response to your request regarding the phone call, yes. The issue there is not that you have considered the argument on this point and rejected it; the issue is that you are completely unaware of the significance of the forgotten phone call. I identified the phone call merely as an example of the body of evidence against Knox.
Only if you assign zero weight to the evidence rendering conspiracy between them unlikely.
Well, assuming for the sake of argument that (1) Knox and Sollecito were involved in the murder; and (2) there was absolutely no conspiracy as you have defined that term, are you saying that your a priori probability estimate of physical involvement by Knox and Sollecito is 1000 times higher than no physical involvement?
If not 1000, then what?
But when you have no evidence of private meeting, no phone records, no email records, and a very short time frame in which any sort of communication could have taken place, and you don’t adjust your likelihood of communication downwards at all,
Are you saying that I have done so?
Then why are so many primary suspects and even convicts later proven to be innocent?
I dispute that “so many” primary suspects and even convicts are later proven to be innocent. How often do you think this happens? What is the percentage of convicts who are later completely exonerated? Surely it is far less than 10% and I have allowed a 10% chance that Knox and Sollecito are innocent.
In fact, when I put it in words, I have to wonder I’m still arguing about any of this. Thus far you have shown a tremendous unwillingness to update in favor of any exculpatory evidence
The only exculpatory evidence you have offered (which I have not already considered) is based on your non-expert opinion. I have patiently explained to you the effect it would have on my probability estimate if you were able to document your opinion.
Or is there some other piece of exculpatory evidence you think I am not considering in my probability estimate?
you insist on demanding a particular piece of evidence
Look, you are the one who is proposing that additional traces of Guede on Kercher would not have made it into the public record. I am asking for you to back up that claim.
Seriously, if you want to continue this debate, show me some evidence that you will actually update in the face of more evidence against your position. In the beginning of this debate, you said that you were aware that the DNA evidence against Knox and Sollecito had been challenged. In the face of the independent experts’ report indicating that there is no valid DNA evidence against them, and Moore’s expert claims for all the evidence we should expect to see in the case of the sort of involvement alleged by the prosecution that we do not see, you update your probability by… nothing. You say you would update your probability were I to provide the right references, but when I offer to make the effort to obtain those references in exchange for a comparable effort on your behalf to produce evidence for your position (I offered you to substitute evidence for any of your assertions if you suggested the substitute first and I agreed that it was appropriate,) you evade. Why should I think this conversation is worth my time? You’ve given me every reason think that if I go to further efforts, you’ll just find more excuses not to update.

Seriously, if you want to continue this debate, show me some evidence that you will actually update in the face of more evidence against your position
I already conceded that my probability estimate would drop from roughly 90% to roughly 30% if you could substantiate your claim about transfer of DNA traces.
But anyway, I am not particularly interested in debating Knox’s actual innocence with you given your ignorance of the case against Knox.
In the face of the independent experts’ report indicating that there is no valid DNA evidence against them
That’s not what the independent expert report said, as far as I know.

Nonsense, you are the one who is evading; since it’s not even clear that you dispute my “position” on the point and you refuse to clarify your position. You demanded evidence for a strawman position you set up.
I will ask you one last time, if you evade or ignore we are done:
Assuming for the sake of argument that (1) Knox and Sollecito were involved in the murder; and (2) there was absolutely no conspiracy as you have defined that term, are you saying that your a priori probability estimate of physical involvement by Knox and Sollecito is 1000 times higher than no physical involvement?

ETA:

I don’t know, what exactly are you trying to accomplish?
I don’t want to get sucked in by replying to more of brazil84′s comments, but in the spirit of this quote (edit, link fixed,) in case it will help me to do better in future...
By the way, if any lurkers are reading this, I will point out the fatal flaw in Desrtopa’s reasoning on the 90% to 30% issue. See, the prior probability of Knox and Sollecito being involved in the murder but not physically is quite low. But the prior probability of Knox and Sollecito being involved in the murder physically is also low. What matters for my calculation is the ratio of the two probabilities.
I suspect that’s why Desrtopa had to bob and weave with my questions on this issue.
Did it look to anyone else like I was bobbing and weaving with my responses to these questions? My perception was that I answered these questions in a straightforward way, but I may have been suffering from illusions of transparency.
You definitely got somewhat sucked into “debate mode”, and you often had far too many points lobbed at you to have caught all of them. It would seem to be possible for brazil84 to honestly have thought you were evading something, but I don’t think an outside observer should have thought so.
That you seem to have kept your cool throughout this ridiculous exercise is a credit.
We are done. You’ve given me no more reason to think there’s any point in having a conversation with you.
Ok bye.

I suspect that’s why Desrtopa had to bob and weave with my questions on this issue. Because he knew deep down that there is no basis to think that this ratio is wildly lopsided. And if the ratio is not lopsided, then it’s perfectly reasonable to go from 90% to 30%.
I enjoy debating and I am fascinated by situations where the popular view is wrong. Also, I like debating where there isn’t anything important at stake.
Once in a while I learn something from debating with someone who disagrees with me.

I strongly suspect that you are incorrect about which side of this debate has more adherents. Neither LW nor Wikipedia are likely to be representative.

I hope to learn something in every discussion I have. Debate is for changing people’s minds. Debate for its own sake is pointless (aka—I don’t debate Flat-Earthers).
You don’t seem interested in saying something that I can glean insight from, and you don’t seem open to changing your mind.
Actually, I’ve done that before. It helps a surprisingly large amount in getting one to realize how astronomy can easily pay rent. And it really tests how well one understands how much historical scientists did really careful, clever observations. That said, I can’t plausibly argue that this is a good use of one’s time, merely that is probably marginally better use than say playing Farmville.

On this discussion board, the popular view seems to be that Knox is most likely innocent. I make no claims about what is believed in the world in general.
You don’t seem interested in saying something that I can glean insight from, and you don’t seem open to changing your mind.
The second part is incorrect—I am open to changing my mind. As far as the first goes, I don’t know where you are at in terms of insight so I couldn’t say.

In any case I don’t think this particular comment deserved to be as down voted as it was.

First of all, just because they aren’t completely exonerated does not mean they are not innocent. A better question is what the percentage chance of innocence is.
Second of all, this assumes that letting a guilty person go free and sending an innocent person to get punished is of equal weight, which it is not.

The discussion is about the probability of actual guilt, not the expected utility of punishment, so that’s not relevant.
ETA: Relatedly, I’ve commented elsewhere that a 90% probability of guilt for murder should be well within the “not guilty” verdict range.
Oh right, good point.
