Prediction failure

I'm going to make a radical suggestion, here.

If you make a prediction, and what you are predicting fails to materialize, there is something fundamentally wrong with your model of how things work.

That's the way it goes in science, you know?  Scientists build theories -- models of how a system operates -- then use those theories to generate predictions.  If experimental data proves to be inconsistent with the theory's predictions, then it's time to revise the theory, or else trash it entirely.

It's a pretty elegant system, and not really that hard to understand.  So why is this so antithetical to the way a great many people think?  Because just recently, there are a group of people who have had their predictions fail, over and over, and all it seems to do is make them louder in defending it the next go-round.

Let's start with the whackjobs who thought that the military exercise Jade Helm 15 was a thinly-veiled cover for a end run by the federal government that would result in a takeover of Texas, the declaration of martial law, the widespread confiscation of guns, and the execution of citizens who objected.  The conspiracy wingnuts who believed this went so far as to hold rallies, demand public meetings in which explanations were demanded from military leaders, and send out armed monitors to keep track of what the troops were doing out there in the desert.

And then... and then... none of that stuff happened.  Jade Helm ended on September 14, Texas is still Texas, no martial law has been declared, Americans are as heavily armed as ever, and the government's stockpile of guillotines is still unused.  I wonder if we can get a refund on them?  I bet they kept the styrofoam packaging.

But are any of the militiamen types who were running about thumping their chests in June standing up, red-faced, and saying, "Wow, I guess we were wrong.  What goobers we are."?  Not that I've heard.

Then we have the ever-entertaining Glenn Beck, who has been claiming for years that the End Times are starting.  Every time something awful happens -- which, admittedly, is pretty much every day, global conditions being what they are -- Beck says, "This is it!  We're in for it now!"  And then... the world doesn't end.

Kind of anticlimactic, that.

About a month ago, Beck said the following on his weekly radio show:
What's coming is God saying, right now, to us, 'Please don't, please stand up, please!  Please stand up and choose me.  Please choose me.  If you don't, I can't protect you anymore.  Don't you see what is happening in the world?  Don't you see what's coming your way?  I want to protect you!  If you don't choose me, I can't!  We've made a deal: I'm your God, you're my people; if you reject me as your God and you pick other gods, I can't take you as my people any more.'
"This is not the run of the mill time anymore.  This is not 'it's coming' anymore.  This is it, gang.  This is it.  This is everything I've warned about, everything that I've worried about and I think it's going to happen so damn fast it'll take your breath away.  When it starts to go, you're just going to be 'what?'  Remember when I said at some point evil will just take off its mask and say, 'Raar'? It's going to happen.  Soon.
And what happened was more or less: nothing.  No calamities, no horrific events taking our breath away, and no evil going "Raar."  Just your ordinary stuff that has happened all along.  But does Beck say, "Hmmmm.... maybe I really don't have a direct pipeline to god?"

Of course not.  He just revises his prediction.  "Okay, maybe not soon soon," he basically said, on his show this week.  "But still soon.  You'll see."  Now he's saying the stuff he has been predicting was imminent for the past five years is all gonna happen in 2016.  "I'm terrible at timing," he said, as if that didn't somehow call into question his entire worldview.

Then we had messianic rabbi Jonathan Cahn, who last year predicted that "the Shemitah" -- a cataclysmic event that will usher in the days of the messiah -- would occur on September 13, and would manifest as a massive stock market crash and resultant economic collapse.  But last Sunday came and went with no cataclysm, which was pointed out to Rabbi Cahn by Pat Robertson on The 700 Club.

Man, it's kind of sad when you're so loony that Pat Robertson calls you out.

Cahn immediately went into backpedal mode:
Nothing has to happen.  You can't put god in a box or he'll get out of it.  The stock market wasn't open on Sunday, so you can't have a crash.  But what's happening with the Shemitah is, there are several templates in the book about how the different ones have come in the past forty or fifty years.  This one has... two of them have had a crash on Elul 29 [the Jewish calendar date that corresponded to September 13], but this one has a different pattern, and that's what this has done.  This is called the pattern of this [sic].  When the Shemitah has happened in the last cycles, what has happened is that in the days before the last day, the stock market, which has been ascending, the Shemitah changes that direction, and it starts to descend.  That has happened in this one as well.  It started in the summer...  It has followed the major pattern.  And this time is called the Shemitah's wake, and sometimes you have the worst crashes occur then, so we'll see what happens.  
Bad things will happen!  Maybe on the date I said, but if not then, they'll happen either before or after that!  Like the stock market going up and then going down!  Because that never happens unless it's ordained by god!

People complain when the weather forecasters get it wrong occasionally.  These bozos, on the other hand, can have a zero batting average, and they continue to get television interviews and have weekly radio shows.

I don't get it.  I mean, I know that the folks who made the predictions themselves are interested in face-saving -- but why don't their followers go, "Whoa.  These people are crazy."?  Instead, every time some new apocalyptic nutjob pops up, spouting prognostications of doom, there are large groups who simply follow along, baaing softly, seeming not to notice that such forecasts have been wrong every single time.

It may be the only undertaking in which a zero success rate doesn't have any effect whatsoever.

Okay, maybe I'm being overly optimistic to expect that people would apply the principles of scientific theories to beliefs that are fundamentally unscientific.  But you'd think that human nature -- which, as far as I've observed, carries with it a dislike for being duped -- would kick in at some point, and the conspiracy theories and apocalyptic prophecies would not gain traction any more.

Never seems to happen, though.  

But it'll happen in 2016!  On February 10!  You'll see!  The whole human race will abandon superstition, and the days of goofy counterfactual beliefs will be over!  Thus sayeth the prophecies!

Cross my heart and hope to die.

The stars of Wall Street

Last week, Marketplace ran a story entitled, "Astrology Guides Some Financial Traders."  Thinking that the headline couldn't possibly mean what it seemed to mean, I read the article, and found that yes, in fact, it did.  The author, Heidi Moore, reports, in all apparent seriousness:
(T)he course of true investing never did run smooth, and there are some traders who look to the stars to tell them what to do. Financial astrologers like Karen Starich say traders know they're up against a lot of rich, smart people.

"They want to have that edge," she says. "They want to know what the future is."

Starich chargest $237 annually for her newsletter... (which contains) news of what will happen to the stock prices of companies, or even bigger, to the Federal Reserve.
So, we have the people who are responsible for managing investments, who are the heart and soul of the Stock Exchange, making their decisions based on... horoscopes?  Apparently, yes:
(Starich) sees dark times ahead in the Fed's horoscope.

"They now have Saturn squared to Neptune, which is really bankruptcy," Starich explains.
Neptune represents money. But when Saturn shows up in a chart, it indicates restriction. So for the Fed, that means the "fiscal cliff is here, and there’s no place to go except to print more money or unravel these financial institutions," Starich says.
But... but... really?  Are we talking about only one or two wingnuts, here?  The answer is no.  Three hundred Wall Street traders subscribe to Starich's newsletter; her rival, "financial astrologer" Arch Crawford, is even more successful, and has a newsletter that is delivered monthly to a readership of over 2,000.  Crawford is also predicting setbacks in the nation's finances, but not because "Saturn is squared to Neptune;" no, he says we're in for trouble "because Mercury is in retrograde:"
Crawford warns his 2,000 subscribers particularly against the dangers of Mercury in retrograde, a time when the planet appears to be going in reverse across the sky. The phenomenon, which happens three times or more a year, indicates a month when communications will be screwed up. He warns his subscribers never to start anything new during that time. He points to the fact that Knight Capital launched a new software program in August, when Mercury was in retrograde, and the brokerage firm nearly went out of business. He also notes that most major market glitches have happened while Mercury was in retrograde.
Can I just point out here that Mercury isn't really traveling backwards?  That it's just a sort of optical illusion based on the relative motion of Mercury and the Earth?  That there is no possible way it could have any effect on events anywhere?  That since it happens three or four times a year, for several weeks each time, that of course there will be times when "market glitches" occur during those periods?

That there is this thing called confirmation bias?

Crawford reports that some traders are cautious about letting people know they're making their decisions based upon the stars, and one even asked Crawford if he could have his newsletter delivered "wrapped in brown paper."  At least this is a hopeful sign; on some level, at least a few of these people are aware that what they're doing is ridiculous.

I don't honestly know what about this story appalls me more; that serious financial professionals are relying on astrology to make their decisions, or that a respected and credible media source published this article and treated its subject as if it were completely plausible, with only the weakest of caveats at the end that "...most people would say... (astrological predictions coming true are due to) coincidence."  What's next?  Tarot card readings by stock brokers?  Seances to consult deceased economists?  Sacrificing a goat to assure a good return on investments?

If so, I'm sure Marketplace will be the first to tell us all about how well it works.

Some days I just despair.
