From their Flash "Quick Tour", they describe the Contextual Filter:
Eliminate delivery of ads that would be inappropriate to serve on pages.
The words are: Chaos, Tragedy, and Death.
I know death has been proven to be one, but the others?
Just thought it was interesting. Hope this helps.

That said, I still see PSAs on the home page where a summary of the google article appears, though I couldn't say if they were more or less frequent since posting the article.

And of course words related to content areas prohibited by the TOS.
I think the issue is not the keyword itself but whether any advertisers are bidding on the words.
That's definitely a reason that PSA/AAs are displayed on some pages, but trigger words are also a very real reason. I've been using AdSense since late June on a crime information site and for the first few months the "negative content" (Google's words) triggers regularly resulted in 80-100% of impressions across hundreds of pages resulting in PSA/AAs. Of course I was only able to *accurately* measure this once the AA option became available.
Until I accidentally triggered the negative content filters [webmasterworld.com] a week ago, PSA/AAs were down to 5-10% of impressions over the preceding several weeks (6-figure total impressions). Based on testing I described in the above thread and AdSense behavior on pages visited by Mediapartners since then I am certain it was a negative content trigger issue.
Here are some more relevant threads from the past on the topic. There are plenty more threads besides this, but I had these handy.

I know death has been proven to be one, but the others?
I am running a page on my site that has the word death in the following tags.
<title>
<h1>
<h3>
And also emphasized in a couple of places.
I have never seen PSA's on this particular page and ads are very nicely targetted to the content. Oh and the page mentions google in the forementioned tags as well.
the page i'm referring to has plenty of available ads for the subject matter (as evidenced by searching in google).
If you mean because Adword ads appear for searches related to the content of the site, keep in mind that not all Adwords advertisers choose to participate in the content site advertising. I've found that the only way to rule out lack of advertisers is to find pages with similar content on other AdSense publisher sites.
Based on what you described your friend's site is similar in content to one of my sites which has definitely had certain words trigger the negative content filters so I don't doubt that is the reason PSA/AAs are showing though.
