Comment: Re:Minimum retrial (Score 1) 172

All we know from the study is that the false positive rate was about 89%

Exactly. We don't know the false positive rate in the cases where the evidence was used. You can't claim that my speculation is not valid, yet yours is valid.

This isn't a case of a random subset of a larger population. In every case, there was a decision made whether or not to use the hair evidence. That decision was based on the evidence available. Thus, you can't assume that you have a random subset of the larger population. Thus your projection of an 11% false positive rate on the subset isn't valid.

Finally, a lack of other evidence would suggest a higher likelihood of innocence, which would imply a higher liklihood that the hair evidence was false.

There is nothing indicate that the rate would be any different among samples that were used in court.

When hair "evidence" was used in a little over 10% of the times that it was available, it's reasonable to think that a lot of selection is going on.. It's reasonable to assume that those cases where the hair evidence was used were not typical. It's very reasonable to assume that the reason the hair evidence was used was lack of alternative evidence. It's not reasonable to make the assumption that the percentages would be similar when the number of cases when hair evidence was used in court is such a small proportion of the overall percentage.

In your world, lack of evidence for a proposition is evidence of an alternative proposition? You have no evidence to support your claim that the 11% of all false positives also applied to hari evidence used in court. Nothing. Nada.

it is very reasonable to assume that the 11% of false matches are over-represented in the 268 cases

Pure speculation on your part, there's nothing to support that assumption.

And your claim that the 11% false positives (of all analysis) applies to the subset cases where hair analysis evidence was used at trial? Where's your evidence to support that claim? It's no more than speculation.

You have no more evidence than I do, but at least I have a rational explanation why it's likely to be greater than 11%.

Re-reading the article, I think that I know where you got the 90% number from, but I think that you are wrong.

Firstly, as you note in another post, it's 89%, not 90% (bias showing here?)

However, more importantly, it's 89% of all the "positive" results, not 89% of those used at trial. In the 11% where there was a false match, the likelyhood of actual guilt is lower, so the amount of other evidence would be much lower, thus it is very reasonable to assume that the 11% of false matches are over-represented in the 268 cases where the hair evidence was used at trial. Thus, your estimate of 27 or 28 is likely to be very low.

They rarely, if ever, produce results that are even vaguely related to what I'm searching for. They don't have market share because THEY SUCK.

Exactly. I find that Google produces better results for searches relating to Microsoft products.

Some time back when Microsoft was advertising their website the showed Google results side-by-side with Bing (with the intent that Bing would give more useful results), I tried the side-by-side website and the Bing side did not even load.

Why is that the government's job? Shouldn't that be the job of ISO, ANSI, or the AMA (all NGOs)?

Because they failed. Standards organizations don't get involved unless the companies in that technical field want them to be involved.

It looks like medical records companies don't want standards -- probably because they would prefer to seek an effective monopoly through proprietary standards. However, enforcing open standards benefits society and that's why government should be involved.

Government doesn't have to develop a standard, merely mandate the requirement for a standard.

They HAVE asked Netflix to pay for the capacity upgrade at the border gateways -- capacity that is being used in large part by Netflix and is making Netflix money. Netflix is profiting from a peering agreement that Comcast has to pay for. Seems fair to me that Netflix pays part of the costs of upgrade.

The cost for Comcast increasing its capacity at the handover point was a few thousand dollars. It wasn't money for upgrades that was holding up the capacity increase, it was money to pay the t[r]oll.

What must life be like for crypto experts at the NSA? I assume that they are smart people, who must surely realize what a boneheaded idea this is. Imagine working somewhere where your most senior bosses go around publicly showing off their lack of knowledge.
