Nate Silver acknowledges he could be wrong

He recommends the linked critique to explain possible flaws in his model. Of course, he disputes the analysis.

Silver takes state polls at face value. This could be a problem:

In a nutshell 1) Polls historically have underestimated Republican performance; 2) Polls historically have overestimated incumbent support; and 3) state polls indicate a turnout advantage for Democrats even larger than the one they enjoyed in 2008 and there are several reasons why this is unlikely to materialize.

The author believes Obama is still the favorite, but the odds are 60/40, not the 83/17 Silver calculates.

by Concern Trollreply 8911/07/2012

I'm glad you labeled yourself as a concern troll but please go the fuck away. Everyone that's not an idiot knows that if the state polls are wrong that Silver's (and everyone else's model) will be wrong. No shit. The idea that every pollster has been so consistently wrong is small, and guess what Silver acknowledges that possibility and that is where the Romney chances of winning come from.

God I can't wait for this election to be over, the amount of trolls it has brought to the board is insane.

by Concern Trollreply 211/04/2012

Agreed r2. It's not quite as bad as the Hillary/Obama wars, but it's pretty fucking awful.

by Concern Trollreply 411/04/2012

You couldn't post this on the Poll thread, OP?

I wonder why?

You know R2 is right about you.

by Concern Trollreply 511/04/2012

This morning George Will predicted that Mittens will carry Minnesota -- which would make it the first time the GOP carries that state since 1972 -- because the same-sex marriage amendment will bring out all the evangelicals.

by Concern Trollreply 611/04/2012

1) George Will is an ass.

2) There is no poll in existence showing Romney even close in MN.

by Concern Trollreply 711/04/2012

You mean the 80/20 Silver used to calculate, or you mean Silver is playing his own devil's advocate?

by Concern Trollreply 811/04/2012

You're not a "worrier" you're a shit-stirrer.

You don't "upset" anyone, just annoy--like a fly or a bad smell.

by Concern Trollreply 1411/04/2012

OP, I share your deep concern!!! (wrings hands in agony) Oh, what is to be done???

by Concern Trollreply 1611/04/2012

I wonder if Silver's model accounts for the "Bradley Effect". That's the uncertain thing that has me the most worried about this election.

by Concern Trollreply 1711/04/2012

For Nate Silver to be "wrong" a number of state polls would have to be wrong. State polls have historically been accurate 97% of the time.

by Concern Trollreply 1811/04/2012

First you freepers try to paint Nate as a hack then spend the 11th hour saying he might be wrong, so Romney might win.

If Nate is so useless, surely you have other evidence of Romney's "chances."

If so, please share.

by Concern Trollreply 1911/04/2012

George Will is delusional.

MN hasn't gone repug in my lifetime and we sure aren't going to start with Romney.

by Concern Trollreply 2011/04/2012

Also, remember his track record. He was the closest of anyone to calling both the 2004 and 2008 elections.

The last I heard, George F. Will was not especially renowned for his statistical abilities.

by Concern Trollreply 2111/04/2012

R17, the country isn't the same place it was during Bradley's 1982 campaign. I don't think there will be any significant effect.

by Concern Trollreply 2311/04/2012

I've yet to meet a white person who wasn't voting against Obama to shout it from the rooftops. And all those white people who are voting for Obama, haven't exactly been shy about it either. I think the Bradley Effect is dead in this election.

by Concern Trollreply 2411/04/2012

Those who think that gay marriage might tip the scales in Mitt's favor in MN should remember California in 2008: Obama won the state handily in spite of Prop 8 being approved.

I hope that marriage equality becomes a reality for MN, but if it doesn't I don't think that will lead to a Romnney win there.

by Concern Trollreply 2511/04/2012

R6, if this were 2004 I guess he might have some point, but... it's now 2012. Same-sex marriage isn't quite the lightning rod issue it used to be (even in past two years support has gone up dramatically). A majority of Americans now support it. In Minnesota, polling shows the anti-marriage amendment is headed towards defeat (and Obama towards a comfortable win).

I would not be surprised if there have been shifts in evangelical attitudes and motivation about the issue as well - certainly it's hard to believe they're as fired up about the idea as they were a decade ago. In any event, the clearest sign that there won't be some surprise groundswell of turnout for it is that it hasn't been a focus this election cycle - Republicans have let his vocal support of same-sex marriage go largely unremarked upon. They don't want to alienate the moderates and the majority position.

So yeah, maybe George Will needs to refresh his assumptions about what gets people out to vote (the same way Karl Rove apparently has). And just as there may still be evangelicals motivated to vote on it, there will still be plenty of young people, liberals, and LGBT-friendly groups motivated to get to the polls to defeat the amendment as well.

It's kind of like people still being stuck in the mindset that the polls are unreliable because of the "Bradley Effect" and voters not being comfortable with a black president - I mean, go look at the 2008 polls and the actual results already to see if any of that played out (it didn't).

by Concern Trollreply 2611/04/2012

R26, R6 is just trying in insult/upset the gays.

Ignore.

by Concern Trollreply 2711/04/2012

Oops, saw that others remarked on the "Bradley Effect" - I don't even know what the reasoning is for that still being a concern for this election.

Like, in 2008 the argument was "white voters will tell pollsters they're supporting the black candidate because they want to appear socially liberal, but in the voting booth their real attitudes will come out."

At this point, President Obama is no longer "the black candidate" - he's been president for four years. There are plenty of reasons to form an opinion about his desirability as president, and trying to appear cool by supporting "the black candidate" really isn't on anyone's mind.

If anything, it seems there's more chatter about "the Bradley effect" for Romney. That Republicans will publicly express their support for him in polls, but private concerns about his Mormonism (especially among evangelicals) will come into play for voter turnout and at the voting booth.

by Concern Trollreply 2811/04/2012

Uhh, if you understood anything at all about statistics you'd know that Nate Silver implicitly acknowledges he could be wrong in everything he does, because that's the nature of what he does. But his best critics (that is, those who DO understand his work well enough to point out flaws in it, like Sam Wang) give Obama better odds than Silver, anyway.

Now go away.

by Concern Trollreply 2911/04/2012

Because he knows the Rethugs fucking cheat. Someone is going door to door in Boulder CO right now collecting ballots, but it's a scam.

Motherfuckers should go to jail for 50 years for election fraud. Maybe then they would think twice.

by Concern Trollreply 3011/04/2012

Thank you r29. The lack of statistics literacy is truly astounding. I mean, at least some meatheads still follow baseball stats, right? That's how the Freakanomics guys and whole slew of other economists and statisticians got "hooked".

by Concern Trollreply 3111/04/2012

Hey you condescending morons: This is not a question of the inherent uncertainty in statistics. It's a question of a defect in Silver's model. Which is why Silver himself referred us to the article. Assholes.

by Concern Trollreply 3211/04/2012

From the author's bio:

[quote]The Wall Street Journal has called him a "leading tort-reform advocate."

[quote]serves on the Executive Committee of the Federalist Society Litigation Practice Group

[quote]an attorney on the McCain-Palin 2008 campaign

How shocking that a die-hard Republican would dispute Nate Silver's analysis.

by Concern Trollreply 3311/04/2012

YAWN

by Concern Trollreply 3411/04/2012

It is not shocking at all. But that's not the point. Silver disagrees with the author's conclusions but respects his arguments enough to refer his reader to them. So regardless of the motivations of the author, Silver believes his points are worth considering.

by Concern Trollreply 3511/04/2012

As to Nate Silver, nobody who works heavily with statistics is unaware that they can be misleading at times. Silver is very good at this game, and he constantly backchecks on possible sources of error in his models, even though he believes them to be correct. He has been very full in explaining why he has come to the conclusions he has, but also quite honest in acknowledging that polls are no substitute for actual votes. 538.com is pretty clearly the best political website going (at any rate, for popular audiences), but it cannot promise more than it does, which is an educated surmise about the overwhelmingly likely outcome of the election.

by Concern Trollreply 3611/04/2012

R32, is there really anything wrong with Silver's basic methodology? He put it pretty plainly the other day - there's certainly a possibility (around 15%) that Mitt Romney could win the election - this is about the chance that the vast majority of polls coming out of swing states are all incorrect and statistically biased against Romney.

Whether you think Silver has some "secret sauce" that he's getting wrong, it's hard to dismiss the numbers: out of 22 battleground state polls that came out Friday (covering 10 different states), 19 showed Obama ahead of Romney, two showed a tie, and one showed Romney ahead in Florida.

If Silver ends up being "wrong", it'll be because the source of his data - state and national polls - are wrong, not because his "secret sauce" didn't work.

There's really nothing confusing or earth-shattering about looking at a lot of polls that show Obama is ahead in several key states, and saying Obama will win.

Sure, you can get into more granular detail (did Silver get the exact percentage right? The exact number of Electoral Votes?) but those are more academic betting questions than of major concern as to who will be elected.

by Concern Trollreply 3711/04/2012

So your point, OP, in yet another obsessive post of "concern" about Nate Silver is that the polls still say Obama will win.

And?

You do know if both the Silver critic and Silver are correct - i.e., Obama wins -- the difference of an 80/20 chance that he would win and a 60/40 chance are ... um... irrelevant? nonexistent?

by Concern Trollreply 3811/04/2012

[quote][R32], is there really anything wrong with Silver's basic methodology?

Time will tell. The key issue is whether there should be any adjustment to the state polls based on historical patterns or should they be taken at face value.

by Concern Trollreply 3911/04/2012

[quote]respects his arguments enough to refer his reader to them.

I can't find this - would you link to it?

by Concern Trollreply 4011/04/2012

R39, if we take the state polls at face value, Obama clearly wins (I think the Princeton Election Consortium just aggregates them, and has Obama's probability at 99%).

If we take Silver's more conservative weighting, Obama still wins.

It's only if you completely discount the state polls and argue they should all be going the other direction (an Obama +3 should really be a Romney +3), that you get a different result.

THAT sounds much more academically dishonest and likely of being wrong.

I really don't understand the Fox News criticism of Silver - he's just reporting and aggregating the data provided by polling organizations, and spitting out a probability. Take it up with Gallup / Rasmussen / PPP if you think their polls are wildly off.

by Concern Trollreply 4111/04/2012

Nate Silver ‏@fivethirtyeight

If you want a good case from a conservative about why polling sites have Obama's odds too high, @tedfrank has one:

by Concern Trollreply 4211/04/2012

Someone who predicts what might happen in the future admits he "could" be wrong? Really? Shocking!

by Concern Trollreply 4311/04/2012

And P.S. to R32, be careful who you call condescending on the one hand and moron in the same set of keystrokes.

Silver did NOT say there's a flaw in his model. He only acknowledged that there are SOME arguments that the polls are wrong.

Silver's methodology is to take a collective look across polls with multiple methodologies to reduce their error. On that basis, Silver explained that UNLESS the polls are SUBSTANTIALLY biased, they collectively point to an Obama win, and to reverse the findings in enough those polls to get there, the odds are significantly in Obama's favor. OP and R32 can't seem to follow that.

The OP and condescending jerk at R32 is obsessed with Silver, AGAIN I say for irrelevant reasons if both predictions are true.

And who wants to bet OP will come here and tell us there was never an 80 percent chance Obama would win and Silver was wrong.

You are obsessed with Silver, OP. Get help.

by Concern Trollreply 4411/04/2012

Oh yes, R42, that reads like Silver crying that his own model is flawed.

Obsessed much?

by Concern Trollreply 4511/04/2012

He is not saying his prediction might be wrong. He is saying the model that he uses to reach his prediction may be wrong. Not the same thing.

by Concern Trollreply 4611/04/2012

R46, not even that his model is "wrong", but acnkowledging there are legitimate academic criticisms and other viewponts of his particular methodology.

He doesn't necessarily agree with them, but acknowledges there's a rational counter-argument.

by Concern Trollreply 4711/04/2012

R45, just giving R40 the info he was looking for. I accidentally pasted over a bit of into text to make that clear. I have no problem with Nate's methods or conclusion.

What part of "could be wrong" are you having trouble with?

[quote]The OP and condescending jerk at R32 is obsessed with Silver, AGAIN I say for irrelevant reasons if both predictions are true.

What is your basis for this ridiculous conclusion? I started one thread about Silver. What I am obsessed with is defending myself against accusations of being a troll and accusations that I do not understand the nature of statistics.

[quote]And who wants to bet OP will come here and tell us there was never an 80 percent chance Obama would win and Silver was wrong.

Regardless of the outcome, after the election, no one will be in a position to argue that the odds were never 80% .

I'm pretty comfortable with the "moron" characterization, as that word is commonly used on DL. Rest assured, I don't not allege that you are literally a moron.

by Concern Trollreply 5011/04/2012

It's a tweet.

by Concern Trollreply 5111/04/2012

OP/r50

you just proved the accusation you called ridiculous.

again, if the author you are using over and over to build your case and Silver are correct, you won't be able to prove Silver's model was wrong.

which means the whole THREAD you started was ridiculous. if you had a reason to post this - to encourage democrats to vote - it would make sense.

the ONLY text in your post is that you are attacking Silver. you yourself said you mockingly called yourself concerned.

Silver has said there are well reasoned criticisms but does not accept them nor has he admitted his model is flawed. you saying otherwise is absurd.

they both say Obama will win. if Obama wins the whole disagreement about chances of winning are moot.

your post is absurd. case closed.

by Concern Trollreply 5311/04/2012

you are quibbling over chances of winning when both say Obama will win and if they're both right this point will be moot in days. and yet you can't let it go.

and you are exaggerating silver's acknowledgement that a critic makes good points into a claim that Silver admits his model could be flawed.

if you can't get that you're as dense as people are saying.

by Concern Trollreply 5611/04/2012

[quote]you are quibbling over chances of winning when both say Obama will win and if they're both right this point will be moot in days. and yet you can't let it go.

No, I am not. This post is about the methodology of Silver's analysis. I have not discussed the chances of Obama winning except to note that even the author questioning Silver's methods agrees that Obama is the favorite.

The fact that you think this thread has been an argument over the odds demonstrates that you have not understood it at all and that you are using your own imagination, not my words, to make your points.

Good day, sir.

Um R64, calm down. It IS a prediction. Silver's prediction is that Obama will win, with an 83% probability.

by Concern Trollreply 6511/04/2012

Fuck you R65. Nate Silver is not predicting that Obama will win. He is predicting that if the election were held 10 times, Obama would win 8 times and Romney 2 times.

Right now at Bookmaker.eu Barack Hussin Obama and the Democrats are the odds on favorite at -325 which means if you think the left will retain the White House you need to bet $325 to win $100 plus the return of your initial investment.

excerpt: Anyone can make a prediction, and that is the real danger. [bold]Predictions and probability should not be confused[/bold], which is why something like 538 or an event tree is fundamentally different than the talking heads on television.

Actually, yes, they will, since there will be quite a lot of new data available (vote counts and exit polls) that will be compared against the various pre-election polls to determine whether Silver's model was accurate or whether Frank has a point. We will certainly know whether Frank's points 1, 2, and 3 have any validity.

If the polls are wrong in just the way that Frank thinks they are, then Silver was almost certainly wrong in assigning an 83% probability. If they are not, then Silver looks pretty good, assuming, of course, that Obama wins by close to the margin predicted.

That would be just guesswork. Silver sees a 1 in 6 chance that Romney would win and Franks see a 2 in 5 chance. If Romney wins you might argue that Frank had a better model, but you could never go back and retroactively say precisely what the odds were today.

[quote]That would be just guesswork. Silver sees a 1 in 6 chance that Romney would win and Franks see a 2 in 5 chance.

It would be more than guesswork. Frank has made some very specific points that will either be supported or contradicted by the data that will be available on election day. For example, his first point is that "polls have historically had a bias against Republicans relative to how election day turns out."

After tomorrow, we will know for certain whether this point is valid or not. If it is not, Frank doesn't look so good. The same thing applies to points two and three on that blog post. Either they will be upheld or they will be contradicted by the data that comes out on election day.

If they are upheld, then Silver was clearly incorrect in his assessment, since he took none of those into consideration in his model. If they are not, then Frank was equally clearly wrong and Silver's model looks significantly better.

[quote]If Romney wins you might argue that Frank had a better model, but you could never go back and retroactively say precisely what the odds were today.

Yes and no. No, I can't definitively say what the odds are today but I can assess whether Frank's concerns are valid or not. If they are not, I can retroactively say that the probability he assigned was incorrect. If they are, I can retroactively say that the probability that Silver assigned was incorrect.
