Conventional wisdom vs. evidence

Nate Silver has compared pundit analyses of poll data to actual voting results and determined that the pundits get things consistently wrong and in the wrong direction:

This French election was part of a pattern that I began to notice two years ago in elections in the U.S. and elsewhere in the world. Take the 2012 U.S. presidential election as an example. Most of the mainstream media concluded that the race was too close to call, despite a modest but fairly robust Electoral College lead for then-President Barack Obama. But on Election Day, it was Obama who beat his polls and not Mitt Romney.2

Forecasters are overconfident more often than they might realize — and there’s a lot to be said for media outlets erring on the side of caution until a vote has taken place. But France was the wrong hill for anything-can-happen-because-Trump! punditry to die upon. Whereas Clinton led Trump by just 3 to 4 percentage points in national polls (and by less than that in the average swing state), and “Remain” led “Leave” by only a point or so, Le Pen had consistently trailed Macron by 20 to 25 points.

Despite their vastly different polling, however, Trump, Brexit and Le Pen had all been given a 10 to 20 percent chance by betting markets — a good proxy for the conventional wisdom — on the eve of their respective elections. Experts and bettors were irrationally confident about a Clinton victory and a “Remain” victory — and irrationally worried about a Macron loss. In each case, the polls erred in the opposite direction of what the markets expected.

Pollsters have a difficult and essential job, but they’re under a lot of pressure from media outlets that don’t understand all that much about polling or statistics and who often judge the polls’ performance incorrectly.5 They’re also under scrutiny from voters, pundits and political parties looking for reassurance about their preferred candidates. Social media can encourage conformity and groupthink and reinforce everyone’s prior beliefs, leading them to believe there’s a surfeit of evidence for a flimsy conclusion. Under these conditions, it’s easy for polls to be contaminated by the conventional wisdom instead of being a check on elites’ views — and to be the worse for it.

Can't wait to see the polls on the 2018 U.S. elections.

The power in Europe

In a note in the New Yorker on Friday, conservative writer Andrew Sullivan points out that the two most powerful countries in Europe have women leading them, and no one cares:

Angela Merkel and Theresa May currently run their respective countries and Marine Le Pen is only the second woman in the final round of a French presidential campaign. And here’s the refreshing thing: No one seems to care much about their gender. Neither Le Pen nor May is appealing to women as some kind of gesture toward gender solidarity. And their opponents almost never mention May’s or Le Pen’s gender, either.

Perhaps the first female president of the U.S. will have to come from the right, as May, Merkel, and Le Pen do. That position scrambles the gender war in such a way that conservative women may be more likely to succeed in politics than liberal women — at least at first. (The pioneer in this, of course, was Margaret Thatcher, who was subjected to sexist criticism entirely from the left.) It’s also true that feminism in Europe is still, at the political-elite level, interested in getting past gender, rather than obsessing about it. When Le Pen loses the vote next Sunday (as seems likely), the one thing you can count on is that she won’t blame misogyny. It seems as if those who actually succeed in breaking the glass ceiling don’t actually campaign on breaking the glass ceiling. I wonder if the Democrats will one day realize that.

I wonder if we will. Because I would prefer that the first female president be one of ours. But right now, I'd say Nikki Haley is the front-runner.

How to explain the president's empty sack?

Just a quick observation, which I hope to expand upon later. Critics and supporters of President Trump alike have noticed that not only has he failed to achieve anything important on his own in the 102 days he's been in office, but the failures more resemble "a bullshit artist who caves easily and is best either ignored" than one would expect from a self-professed master of the art of the deal. (On the other hand, he has successfully enriched himself and his family through corruption, and will continue to do so until someone stops him, so he hasn't failed in all his objectives.)

But his biggest failure might be not understanding the intense scrutiny of his office and how that affects his deal-making skills. If his entire fortune is based on bluster and bullshit, then having to do all of that in public all the time seriously undermines the strategy. Take Mexico, for example: after gearing up for an intense diplomatic battle with the administration, Mexicans have essentially realized Trump is a paper tiger, and have started ignoring him entirely. That will make it hard for Trump to get any kind of a deal from them.

In short: his success in private, one-on-one deals doesn't translate to public, multi-lateral, diplomatic and political dealing. And he was too ignorant or stupid to see that.

Still think he's a business genius?

The merry month of May

April seems to have gone quickly this year, but that could just be my advancing age. I'm hoping to have a little more inspiration this month to return to 40+ blog entries a month—i.e., the running average since November 2005. For the 12 months ending yesterday, my average (mean) has been 34.4 with a median of 35, just barely holding above 1.0 entries per day.

Of course, the total number of entries doesn't really matter if they're good. Deeply Trivial took part in last month's A-to-Z blogging challenge, and did a fantastic series on basic statistics that's worth reading. Her 26 entries (plus 5 bonus posts) provide almost a complete intro course in statistics. Start with X and then bounce back to A.

I'm also glad to see center-right commentator Andrew Sullivan back on the Internet, even if only once a week. His column from yesterday, "The Reactionary Temptation," is a must-read.

And, of course, Josh Marshall's frequent posts from the center-left will be vital in keeping tabs on the sub-surface wrigglings of the current administration.

May should see more activity on The Daily Parker for reasons I will get to later in the month. It's time to get writing again.

Another milestone on the way to planetary disaster

The Mauna Loa Observatory in Hawaii announced this week that the atmosphere passed 410 ppm of carbon dioxide and is heading for a monthly average of 407 ppm, the highest values observed on earth in millions of years:

Carbon dioxide concentrations have skyrocketed over the past two yearsdue to in part to natural factors like El Niño causing more of it to end up in the atmosphere. But it’s mostly driven by the record amounts of carbon dioxide humans are creating by burning fossil fuels.

“The rate of increase will go down when emissions decrease,” Pieter Tans, an atmospheric scientist at the National Oceanic and Atmospheric Administration, said. “But carbon dioxide will still be going up, albeit more slowly. Only when emissions are cut in half will atmospheric carbon dioxide level off initially.”

Even when concentrations of carbon dioxide level off, the impacts of climate change will extend centuries into the future. The planet has already warmed 1.8°F (1°C), including a run of 627 months in a row of above-normal heat. Sea levels have risen about a foot and oceans have acidified. Extreme heat has become more common.

Too bad all that data isn't persuasive enough for some people. I guess the planet just needs better P.R.

Top o' the mornin'!

No. Just no.

That's what Irish officials visiting Washington are saying today, after American politicians made a cringe-worthy series of gaffes on St. Patrick's Day:

“Top of the morning,” said Vice President Pence, as he hosted Irish Prime Minister Enda Kenny at his residence for breakfast Thursday.

Really? The reaction by Irish on social media was palpable.

“Literally just shouted ‘NOBODY SAYS THAT’ at the TV,” a journalist in Ireland tweeted. “I’ve literally only ever heard that said by Americans,” another person said.

At [a] luncheon, Trump shared what he claimed was an “Irish proverb.”

“As we stand together with our Irish friends, I’m reminded of an Irish proverb — and this is a good one, this is one I like, I’ve heard it for many, many years and I love it,” Trump said. “Always remember to forget the friends that proved untrue, but never forget to remember those that have stuck by you.”

Irish tweeters immediately displayed skepticism.

These guys have attitudes about fellow Americans that would embarrass Roger Taney, so is anyone really surprised they get it all wrong with everyone else too?

Did the President actually ask Congress to investigate him?

Several reactions to President Trump's bizarre accusation that the Obama administration ordered an illegal wiretap on Trump Tower last year, from left to right:

Meanwhile, Greg Sargent sees this as more evidence that Trump has "total contempt for American democracy." That does seem to be the case.

Dump Trump rump

Remember the American tourism industry?

Travel site Frommer's reports that foreign travel to the U.S. has plummeted since the inauguration, for obvious reasons:

[T]he prestigious Travel Weekly magazine (as close to an “official” travel publication as they come) has set the decline in foreign tourism at 6.8%. And the fall-off is not limited to Muslim travelers, but also extends to all incoming foreign tourists. Apparently, an attack on one group of tourists is regarded as an assault on all.

As far as travel by distinct religious groups, flight passengers from the seven Muslim-majority nations named by Trump were down by 80% in the last week of January and first week of February, according to Forward Keys, a well-known firm of travel statisticians. On the web, flight searches for trips heading to the U.S. out of all international locations was recently down by 17%.

A drop of that magnitude, if continued, would reduce the value of foreign travel within the U.S. by billions of dollars. And the number of jobs supported by foreign tourists and their expenditures in the United States—and thus lost—would easily exceed hundreds of thousands of workers in hotels, restaurants, transportation, stores, tour operations, travel agencies, and the like.

Wow, didn't see that one coming. But hey, with the euro at $1.05 and Sterling at $1.24, maybe it's time to check airfares?
