Comment Re:The Odds (Re:Deliberately causing panic) (Score 1) 604

I haven't done any research on stats beyond following the bIONG bOING link in the grandparent, but that said, "28 per cent of Canadians and Americans contracted the Spanish flu". That means they caught it. The 5% death was also going from the grandparent as translating "Well over 9 of 10...". For the 47M I used the lower bOING bOING stat of 2.5% deaths, "Worldwide, an estimated 2.5 per cent of the sick died of complications".

It's obviously a wildly rough estimate, which doesn't take into account things which would make it better or worse now, or better or worse in some places than others, but as a wildly rough estimate it's not way off. And it's just intended to point out that the framing of the statistics which is supposed to make us feel better is in fact saying that it was a horrible plague--not on the scale of smallpox or the black death, but still a horrible plague.

I remain very agnostic about how bad this sine flu will be, though.

This reminds me of those experiments which phrase questions as, "Would you accept a treatment which has an 80% survival rate?" versus "Would you accept a treatment which has a 20% fatality rate?"

Or, around the university here, "social norms" marketing things like "65% of students don't drink and drive."

If 7 of 10 don't catch the flu (3 in 10 do, a very high rate), and (say) 19 in 20 who catch it fully recover (1 in 20 dies, pretty serious bug!), then your chance of dying from this specific thing in a pretty short time-window are better than 1 in 100.

Using the bOING bOING numbers of 28% infection and 2.5% fatality, it still kills 7 out of 1000 people, or about 47 million people worldwide. I think AIDS is killing around 2 million people annually.

So, yeah, those stats don't make me feel any better.

Comment math and results (Score 1) 301

If you've got a good (meaning clear and predictive) mathematical model and it turns out wrong, then that's also useful to know. If you've got intuitions and stories and pictures of data which seem good when explained by the right person, and those turn out wrong--well, that could just be that you were misunderstanding, couldn't it? Can you prove that the approach was wrong when it's fuzzy?

Math will always have an important place in finance, because it can be understood and judged. The alternative way to judge results is by looking at who makes the most money, but even that can be very noisy and misleading at times.

The question isn't whether math will be important in finance. It's (a) whether the particular tools/models commonly used will change a little or a lot, and (b) whether the people using the models will have the understanding and wisdom to apply them only as appropriate.

(a) means if you want to be involved in financial math, try to be broad enough that very different approaches won't be completely alien to you, and (b) means you should study some economics / psychology / business so you can connect the models to the reality.

Comment experiment vs authority (Score 1) 1190

I fall into the scared shit about global climate change thinking we should get on the ball with a vengeance to try to fix it camp.

BUT, I don't entirely trust my own motivations in this regard. Partly it's risk-aversion--if there's a reasonable chance of the nasty predictions, it's worth trying to fix it. Largely it's accepting that the authorities who understand this shit mostly agree. I DON'T understand this shit.

That's different than, for instance, the role of vaccines in causing autism. There's really clear data that it doesn't. Even if I don't understand the mechanisms, all I have to trust is the studies weren't fraudulent and I can be quite comfortable that getting my kids vaccinated won't give them autism.

I haven't seen the equivalent for climate change. Our sample size is awfully small, even if you try to convince yourself different eras are separate samples.

I might be missing something, but if I am, I REALLY want someone to point it out to me, and to the skeptics. Where's the climate change equivalent of the vaccine studies?

My issue with the Wagner wasn't so much that they used it, but that they seemed to do so specifically to be reminiscient of Apocalypse Now, which did the same thing - Fitting, but unoriginal.

My problem with the Wagner is that it took a scene which was supposed to be heavy and instead made it funny--it's so trite now it can't be anything but comical.

O well.

I liked the flick, but I'm really really glad that I'd read the comic before. I think the movie would have been a poor introduction to the story.
