Science as a Bendable Vocation

October 10, 2015
Posted by Jay Livingston

Maybe it’s a coincidence, but the New York Times has three items today suggesting that greed, for want of a better word, isn’t always so good – not for the public and not for science. These articles suggest that corporations sometimes deliberately distort science in order to subvert the general welfare so that they can increase their profits. I hear you gasping in disbelief.

You’re right. It would seem a commonplace observation except that so many people in such influential positions think that the profit-seeking efforts of huge investment funds and energy companies and chambers of commerce all bring unalloyed good to everyone.

1.  In an op-ed, Luigi Zingales warns about scientists nudging their research in directions favored by the people who bankroll them. Would scientists risk their reputations for a few pieces of silver? Under some conditions, yes.

A paper can be misleading or economical with the truth even when not blatantly false. . . . And reputational concerns do not work as well with sealed expert-witness testimony or paid-for policy papers that circulate only in small policy groups.

Then there is what Zingales calls “a scarier possibility”

that reputational incentives do not work because the practice of bending an opinion for money is so widespread as to be the norm.

Zingales does not give any estimate of the location of norm’s current boundary or the prevalence of such bending.

What triggered Zingales’s op-ed is Congressional testimony by economist Robert Litan and Litan’s related paper on consumer protection regarding retirement plans. It turns out that the paper was commissioned by the Capital Group, a trillion-dollar investment group not notably favorable towards consumer protection. The Capital Group generally underwrote Litan’s research, as Litan acknowledged; but they also commissioned this specific project, a fact Litan did not deem important enough to mention. Not surprisingly, the paper found that protecting consumers vis-a-vis retirement-plan brokers would be too costly.

(Zingales, by the way, is no lefty. He teaches at a business school, the Booth School of Management at the U. of  Chicago. I expect that neither he nor Booth see his mission as radicalizing future MBAs.)

It’s not just economists. For a long time we’ve known that research sponsored by drug companies finds drugs much safer and more effective than does independent research (see here, for example).. But government-sponsored research has decreased, and research by Big Pharma has grown. As Marcia Angell, former editor of The New England Journal of Medicine said in 2009,

It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine.

2. Also on the op-ed page (here), Naomi Oreskes discusses the efforts of Exxon (later Exxon-Mobil) to undermine the findings of climate scientists. Internal Exxon documents going back forty years show that the company’s own scientists were telling them that carbon-based energy would change the global climate.

In 1989, the company helped to create the Global Climate Coalition to question the scientific basis for concern about climate change and prevent the United States from signing on to the international Kyoto Protocol to control greenhouse gas emissions. . . . Journalists and scientists have identified more than 30 different organizations funded by the company that have worked to undermine the scientific message and prevent policy action to control greenhouse gas emissions.

Oreskes likens the Exxon-Mobil tactics with those of tobacco companies decades earlier – a strategy to “promote a message of scientific uncertainty” where the science was in fact settled.  Of course today, tobacco companies today wouldn’t take such drastic efforts to undermine anti-smoking policies, would they?

3. The front page of the Times has a story about the Chamber of Commerce becoming the champion of the tobacco industry. The Chamber has traditionally worked for the interests of business in general regarding tax policy and regulation. Under new management in the person of Thomas J. Donohue, the Chamber is taking up the cause of smoking at home and especially abroad. And you thought “Thank You For Smoking” was a comedy.

True, their second-highest official has said, “The chamber is not opposed to tobacco regulation. Declarative statement. We don’t support smoking. Declarative statement.” Declarative but false.

The chamber’s own letters, many of which have been published in The New York Times, show the extent of the tobacco campaign, including an attack on excise tax in the Philippines, cigarette advertising bans in Uruguay and restrictions on smoking in public places in Moldova.

Needless to say, the tobacco industry and the Chamber also do research. Guess what the research finds.

During his first stint with the chamber in the early 1980s, [Donohue] was called on to calm restive cigarette makers, who were angered by a chamber health booklet that said smoking increases absenteeism. Mr. Donohue invited the tobacco industry to “supply some additional data” for a revised version, according to a letter later made public. Within a few years, the industry was citing chamber research that found “smoking has no influence on an employee’s likelihood of being absent.” Philip Morris directed the chamber’s work on a polling project surveying attitudes about government-funded litigation. The chamber took the lead in public, while “PM stays in the background,” a Philip Morris memo outlined. The cigarette maker selected the polling firm and reviewed the questions.

Three articles in one day (and I haven’t read the whole newspaper). Maybe the Times save all its tilted-science articles for Saturday. Or maybe it’s just the Times, and if I had instead looked at the Wall Street Journal I would have found articles about all the unbiased research done by virtuous corporate-sponsored scientists.

How Do You Know If You’re Really a Conservative?

Are Conservative Republicans a breed apart? And are they getting even farther apart?

A recent Pew survey compared attitudes a year ago and last month on the subject of abortion. The 2015 survey was done in the immediate wake of those now-famous videos of Planned Parenthood officials, videos shot surreptitiously and edited tendentiously. The demographic that showed the largest swing in opinion was Conservative Republicans.*

Among people who identified themselves as Conservative Republicans, opposition to abortion rose from 65% to 79%. Four out of five Conservative Republicans now oppose abortion. No other group in the survey comes in at more than half.

(Click on the image for a slightly larger view.)

The obvious explanation is that in the past year, an additional 14% of Conservative Republicans have become more conservative on abortion. The hardliners are becoming even harder. But there’s another possibility – that many of the Conservative Republicans who did not oppose abortion a year ago no longer call themselves Conservative Republicans.

That’s not as unlikely as it might seem. 

The Gallup poll shows that among Republicans, those who identified themselves as conservative on both economic and social issues – the largest segment of the faithful – dropped from 51 to 42 percent.  What if all the dropouts were abortion moderates?

I did some simple math.  I imagined 100 Republicans in 2014. Of those, 51 were self-identified conservatives, and of those 65% opposed abortion. That makes 33 who thought abortion should be illegal nearly all the time.

Last month, only 42 of those 100 Republicans said they were thoroughly conservative, 9 fewer than a year ago.  Of those left, 79% were anti-abortion. That makes 33. In my scenario, these were the same 33 as a year ago. The 9 who defected to the less-than-fully-conservative camps were the ones who were wishy-washy about making abortion totally illegal. Perhaps this is our old friend social comparison. These nine people looked at the hardcore, and the next time that a pollster asked them about where they stood politically, they thought, “If being a Conservative Republican means wanting all abortions to be illegal, maybe I’m not so conservative after all.”

	Conservative Republicans	%Anti- Abortion	Number Anti- Abortion
2014	51	65%	33
2015	42	79%	33

I’m speculating of course. Besides, the data and calculations here are surely too simplistic; I am not a political scientist. But maybe the party purists are indeed forcing others who used to be close to them politically to rethink their identification as Conservative Republicans.

----------------------------

* The drop in support among those 30-49 and 50-64 does fall just outside the confidence interval of 5.5 points, but is only half as large as the change among conservative Republicans.

Images in the Media vs. Poll Data

Sometimes I get the wrong impression from what I hear and see in the media. In the news, Planned Parenthood has been taking it on the chin. A few liberals have come to the defense, but my impression these past few weeks is that this organization has fallen out favor with politicians and the public.

Donald Trump on the other hand seems to have been soaring. He keeps coming out on top in those polls despite all the offensive comments. He is, the pundits tell me, tapping into a rich vein of American populist resentment.

So I was interested to see the results of a recent NBC - Wall Street Journal survey asking people how favorably or unfavorably they viewed people and organizations in the news.  Here is what it shows.

(Click on a chart for a larger view.)

Planned Parenthood did draw some negatives – 31% viewed it unfavorably – but these were more than offset by the numbers of people people whose view was positive. The chart below shows both the Favorable and Unfavorable.

Trump is the opposite of Planned Parenthood. He has his admirers, but while they play an important part in surveys of Republicans, when the survey includes the general population, those supporters are swamped by people less taken with The Donald. The same is true to a lesser extent of Hillary Clinton. Her 39% positive is higher than that of any other presidential candidate. But there are a lot of people out there who do not like Hillary.

Surely there are political scientists who can make better sense of this than I can.

Gun Laws – Paying for False Negatives

October 2, 2015
Posted by Jay Livingston

This video was making the rounds last spring. The video maker wants to make two points:

1.  Cops are racist. They are respectful of the White guy carrying the AR-15. The Black guy gets less comfortable treatment.

2. The police treatment of the White guy is the proper way for police to deal with someone carrying an assault rifle.

I had two somewhat different reactions.

1. This video was made in Oregon. Under Oregon’s open-carry law, what both the White and Black guy are doing is perfectly legal. And when the White guy refuses to provide ID, that’s legal too. If this had happened in Roseburg, and the carrier had been strolling to Umpqua Community College, there was nothing the police could have legally done, other than what is shown in the video, until the guy walked onto campus, opened fire, and started killing people.

2.  Guns are dangerous, and the police know it. In the second video, the cop assumes that the person carrying an AR-15 is potentially dangerous – very dangerous. The officer’s fear is palpable. He prefers to err on the side of caution – the false positive of thinking someone is dangerous when he is really OK.  The false negative – assuming an armed person is harmless when he is in fact dangerous – could well be the last mistake a cop ever makes.

But the default setting for gun laws in the US is just the opposite – better a false negative. This is especially true in Oregon and states with similar gun laws. These laws asssume that people with guns are harmless. In fact, they assume that all people, with a few exceptions, are harmless. Let them buy and carry as much weaponry and ammunition as they like.

Most of the time, that assumption is valid. Most gun owners, at least those who got their guns legitimately, are responsible people. The trouble is that the cost of the rare false negative is very, very high. Lawmakers in these states and in Congress are saying in effect that they are willing to pay that price. Or rather, they are willing to have other people – the students at Umpqua, or Newtown, or Santa Monica, or scores of other places, and their parents – pay that price.

UPDATE October, 6:  You have to forgive the hyperbole in that last paragraph, written so shortly after the massacre at Umpqua. I mean, those politicians don’t really think that it’s better to have dead bodies than to pass regulations on guns, do they?

Or was it hyperbole? Today, Dr. Ben Carson, the surgeon who wants to be the next president of the US, stated even more clearly this preference for guns even at the price of death.  “I never saw a body with bullet holes that was more devastating than taking the right to arm ourselves away.” (The story is in the New York Times and elsewhere.)
