Magic Republicans
To be fair, and I do try to be fair, it’s not just Republicans who do this. My point is that it gains Republicans nothing to be known as the Party of Cruelty and Shame. Come on Reps, you should not allow your party to be represented in this way, because you can be better than that. If you are really interested in reforming your party, you must be.

Merry Christmas from DTA!
Merry Christmas everyone. I am pondering a post on the reciprocity of snow removal, but it just didn't happen today. Perhaps tomorrow, or maybe I'll take a few days off.

Mathematics and Magicians, the Rant Continues
An old friend of mine just wrote in reply my Mathematics and Magicians post yesterday. He couldn’t post his comments directly to the blog site, so he emailed them to me. With his permission, I present it to you here in full (I did add the first two links for reference):
Hey Dan
I read one of your blog entries, and I got so worked up that I furiously banged out a reply. Then the silly thing wouldn't let me post it, probably because it was too long. So I'll just email it to you. You can ignore it or delete it or post it yourself....but at least I will have had my say! And for the record, I'm griping with the author you cite, not you...so we're on the same side.
Here's my reply to your entry "Magicians and Mathematicians":
Having worked in the financial arena for about 15 years now, I'm here to tell you that the term "human side of finance" is as big of an oxymoron as "sanitary landfill" or "military intelligence" or "compassionate conservative". If you want that touchy-feely crap, go down the hall to HR and cry them a river. The finance people have work to do, thank you very much.
All businesses which are traded in the public markets exist for one purpose: the pursuit of profit for shareholders. How the "quants" apply their profit mandate to their daily tasks is merely a matter of corporate policy. It's shockingly naive to assume that anyone in a financial capacity would ever "appreciate...the unintended consequences" of their individual actions or even give a hoot for that matter.
Sounds like a bunch of academic rubbish to me. It would also be foolish to subscribe to the notion that this is a relatively new phenomenon (ref. the managers with history degrees – as if to say “back in the good old days”). The Spanish conquistadors directly or indirectly caused the deaths of millions in the pursuit of profit (unbridled imperialism). The Bolsheviks made a naked power grab in the early 20th century and wreaked 70 years of financial, ecological, and social havoc, all under the pretense of making a better life for the masses (rampant socialism/communism). Wall Street capitalists speculated themselves into quite a mess in 1929 (runaway capitalism).
Greed is an intrinsic part of human nature, and unfortunately greed is also part of the group mentality of "quants" which are otherwise known as "people". It seems the article's author is the one who has lost his "human side".
P.S. I resent being identified as a mere "quant", which sounds suspiciously like “quantum”, especially since the definition of THAT word would be even more dehumanizing.

Ahh........I feel better now.......so it's back to clearing general ledger errors for me!

I will have to investigate if there is a limit to comment length, but after reading Rick's reply I rather suspect that it was a hardware failure instead (his keyboard probably melted!).

Magicians and Mathematicians
Paul Wilmott writes about Magicians And Mathematicians, and I might have a bone to pick.
Quantitative finance and risk management are not just about the numbers. Numbers play a part, but so does the human side of the business. When analyzing risk it is important to be able to think creatively about scenarios. Unfortunately the training that most quants get seems to actively discourage creativity.I certainly agree,
This is really a question about whether modern risk managers are capable of thinking beyond maths and formulas. Do they appreciate the human side of finance, the herding behaviour of people, the unintended consequences, what I think of as all the fun stuff. And this is a nice question because it very quickly sorts out different types of thinkers.
and
[The emphasis is mine. ]Once you start thinking outside the box of mathematical theories the possibilities are endless. And although a knowledge of advanced mathematics is important in modern finance I do rather miss the days when banking was populated by managers with degrees in History and who'd been leaders of the school debating team. A lot of mathematics is no substitute for a little bit of commonsense and an open mind.
How can we get quants and risk managers to think beyond the mathematics? I'm afraid I don't think we can, the way the majority of them are currently educated.
I'm OK with the part about training the quants to understand these things, and it's somewhat criminal that they were not required to understand these things before being allowed to play in that particular sandbox, thus precipitating a financial meltdown. However, this in no way removes the problem from the "box" of mathematics. It's still math, but it has to be applied in a consistent and conservative way, and founded in a basic knowledge of the subject area. -- And now I'm going to contradict my self -- It is more than math, it is statistics. It was once suggested to me that the difference between math and statistics is the manner of application (of stats), which might fairly be described as an art. A herd of quants well versed in the application of statistics ought to have realized the most obvious error (dependencies among risks).
That there is an essential art to understanding financial markets I do not doubt. It's too bad so many people forgot, or were blinded to that fact by greed.
[UPDATE: The rant continues here!]

"that conversation with your child"
Jim Stigl of the Milwaukee Journal Sentinel writes:
Sooner or later you're going to have that conversation with your child, the one about how it all works "down there."
By down there, I mean Illinois.
Children are curious and you can't protect them forever from the harsh realities of life. Maybe the news will be on TV, and they'll turn to you all wide-eyed and say, "What the bleep is a bleeping Blagojevich?"
You need to be prepared. Calmly explain to your child that mommy and daddy love you very much, but there are things that happen to the south of us that are not very nice.
Definitely a Wisconsin perspective - Click through for the full column.

A Matter of Intent?
UK TV station defends plans to show man's death
LONDON (AP) — A British television channel plans to show a film about an American man who commits assisted suicide at a Swiss clinic, reigniting debate over an issue that strongly divides opinion in Britain. Opponents called the broadcast a ratings-grabbing stunt.
I could not find the program online to listen to it again, so excuse me for doing this off the top of my head. The participate representing the government position argued that (among other things) it was inappropriate to show an "intentional death" on television. This reasoning is just wrong. How can anyone say that a peaceful intentional death is inappropriate when the media is full of so much violent intentional death, either real or fictional? I can think of other reasons to object to this program being broadcast, but this matter of intent is a totally bogus, and not a reason to disallow this program as part of the larger debate on assisted suicide.

Blog Thoughts
I had a great time during the election when a good topics were low-hanging fruit, but this also distracted me from my purpose (such as it is) of humorous commentary on science and statistics. This was not intended to be a political blog, but I have come to the realization that some of my topic are politics (ID, among others) so I should admit that politics/opinion will have a large part to play here. ID itself is a topic I'd like to leave behind - except that I'm not quite done with it yet (I have a take on Irreducible
New Topic: I will be starting a series on posts on aging issues. This has become an important personal issue for me over the past few year, and I think I can contribute useful opinion on a personal and professional basis. Expect a few outright rants on this topic too.
I'm considering some chances to the general appearance of the blog; some color adjustments and perhaps a new banner. I have a secret dream of commissioning Phil Foglio to create a banner and associated icons/images for me. That would be WAY cool.
I have created a new email address for the purpose of blog related management and communications; TomatoAddict42 (presumably Tomato Addicts 1 through 41 have already succumbed to the ill effects). I will monitor this new email from my regular Gmail, so this should be a transparent change.
I may start also posting on others blogs as "Tomato Addict". It's not like I really need another online handle, or that I want to conceal my identity, but in order to establish myself as a blogger I think it helps to have a unique identifier (and "Dan" is far from unique).
I'm also hearing really good things about Wordpress, but having just got settled in on Blogger I'm not ready to pick up and move.
There is one final small addition; I've added my Favicon to my post template so it can appear at the end of every post, as I've always intended.

Use this equation 0=NP(20C+B)/75
“Following her [Britney Spears] wardrobe malfunction — where she was snapped nearly popping out of a very low-cut dress at her 27th birthday bash, below — scientists, undies experts and mathematicians have been trying to figure out where the decency perimeter lies. And here we can exclusively reveal the formula to work it out.”

Troubled Waters ... and then a Funny Thing Happened
It was a rousing good argument back on the SciAm.com blog pages - back when they had blog pages - that started off with comments on an article about Ben Stein's movie and continued on for months in an evolution versus ID free-for-all. Those were truly glory days.
Something surprising happened along the way, amidst the endless argument; I made a friend on the other side. A man of education, intelligence, interest in science, and a deep conviction in his faith. A man with whom I have a very fundamental disagreement on the very basis of science, but one whom I could respect and share an honest conversation. He reminded me that people have a basis for what they believe in, and if you are able to really communicate with them, it is possible to reach common ground. At least you can do this with people who are open and honest, and this man is among the best. We still trade notes and news on a regular basis.
Funny things happen - This post started off as another poke at ID, a boost for a fellow blogger and kindred spirit, and a remembrance of how I got started blogging. Somehow my thoughts were turned to the positive experience I got out of my early evolution/ID discussions, completely off-track from what I had intended to write. That is the nature of blogging I suppose, to share your thoughts, and I'm glad I took the time to share this.

An Open Letter to Goodreads
This is getting old. I tried last month to unsubscribe from your newsletter, and still it comes. I am not surprised. I did not sign up for the newsletter either. A close acquaintance signed up (not knowing any better) and Goodreads SPAMMED her entire address book, causing a great deal of grief and embarrassment. Now all these people (and me) continue to receive Goodreads monthly SPAM too; It's the gift that keeps on SPAMMING, and just in time for Christmas.
So, Mr. Goodreads, does this by any chance look familiar?
Do you send unsolicited emails or direct mail?
Goodreads absolutely, positively does not use the emails it collects as a source for unsolicited emails.
It ought to, it's from the Goodread Privacy Policy page. Surely the people at Goodreads have heard the old marketing maxim that if you displease one customer, that customer well tell 11 people, and those 11 people will tell another 4 each, for a total of 45 pissed-off customers. I've seen a few weakly worded posts in response to complaints around the blogosphere, but no real evidence that you are actually changing your Address Book SPAMMING practices, or making any effort to remove any email addresses you previously gathered in this manner.
Your registration pages still guide people into giving you access to their address books, and actually require extra effort (canceling pop-ups AFTER deselecting the check-box) to avoid this to avoid this step. In short, despite your claims that you have improved you practices, there is no evidence of this change.
If Goodreads is serious about changing their ways, and maybe correcting for past wrongs, then they had better get busy.
[Never reveal your email login and password to any program or internet service that you do not absolutely trust, and even then you should be very suspicious. Most certainly do not trust Goodreads to protect your privacy.]
