pseudoscience and the No True Scotsman fallacy

I’m sure the point has been made before, but it occurs to me that to describe shameful episodes like racial eugenics as “pseudoscience” risks the “No True Scotsman” fallacy.

This is an early (possibly the first) telling of the No True Scotsman story, by Anthony Flew:

Imagine Hamish McDonald, a Scotsman, sitting down with his Glasgow Morning Herald and seeing an article about how the “Brighton Sex Maniac Strikes Again”. Hamish is shocked and declares that “No Scotsman would do such a thing.” The next day he sits down to read his Glasgow Morning Herald again; and, this time, finds an article about an Aberdeen man whose brutal actions make the Brighton sex maniac seem almost gentlemanly. This fact shows that Hamish was wrong in his opinion, but is he going to admit this? Not likely. This time he says: “No true Scotsman would do such a thing.”

It would similarly be fallacious to say, “No scientist would claim to assemble evidence for white supremacy. Ah, I see that a whole raft of highly distinguished scientists argued for white supremacy, and a few still do. Well, they are not true scientists.”

If “Racism is pseudoscience” is just a way of saying “racism is false,” then I agree with it. But if it’s meant to imply that the actual practice of science–science as a real human activity–would never support racism, then it’s false. Science did support racism, and that tendency lingers in some quarters. Racist scientists are truly scientists in the sense that they practice that occupation and participate in that social institution. They’re wrong, but that shows that science is susceptible to error–both empirical and moral. It’s not helpful to try to evade the problem by definitional fiat.

22 million new voters by 2020

With The LAMP, a New York City nonprofit that works on media and digital literacy skills, my colleagues at CIRCLE are launching the 22×20 Campaign, which has the tagline “22 million new voters by the year 2020.”

For the night of the State of the Union, 22×20 helped organize Action Parties in “New York City, Washington D.C., Austin, Chicago, Boston and San Francisco with partners such as Austin Public Library, Mikva Challenge, DoSomething.org, KQED, OZY, Sony, and YVote.” Students were encouraged to discuss, analyze, and share their reactions. More information about how to organize such events is here.

The campaign also provides educational resources. For example, you can find lesson plans on media literacy and tutorials on how to create videos using news clips. I thought the guide entitled “Ten Easy Steps to Fact-Checking” was a perfect resource for viewers of the State of the Union.

More events are coming up. Follow the campaign on Twitter (@22millionVotes) or by using the hastag #22×20. CIRCLE also has an explanatory blog post on “Teens and Elections” with valuable background data. 

echoes

In home movies and fading Polaroids,
They look funny, their lapels wide and garish,
Their facial hair risible, movements jerky.
They look naive–fools, ignorant of what came next.
But I report: the grass felt just the same
When you raked your fingers though its crisp stems.
On a suddenly warm January day,
Wafting over sodden drifts, the air smelled
The same, and laughter sounded the same
Filtered through traffic thrum and cicadas.

differences in voting by major

My colleague Inger Bergom has a piece in The Conversation with  entitled “Why don’t STEM majors vote as much as others?” They are analyzing data from the two million college students who are included in our National Study of Learning, Voting and Engagement at Tisch College.

The raw correlations between college majors and voting rates are pretty substantial. In 2016, more than half of all education majors voted (53.5%), which was more than 7 points ahead of the rate for business students.

But majors attract different demographic groups. For example, women vote at somewhat higher rates than men. If more education majors were men, the turnout rates in education programs would fall. By the same token, STEM turnout would rise if STEM majors recruited more women. However, education majors would still be ahead.

Once you zero in on major, race and gender together, you see some interesting patterns. African American women who major in education voted at a 58% rate in 2016, well over double the rate of Asian-American men who majored in business.

Self-selection must be part of the story: people who are more interested in the kinds of issues that arise in politics may also enroll in majors like education. Still, there is room to improve the civic education that STEM and business majors experience.

conflict v mistake as a framework for politics

Scott Alexander has an interesting blog post that distinguishes two ways of thinking about politics:

  1. “Politics as mistake.” I’d put this one a little differently. The core idea is that institutions have flaws that result from their designs and the incentives that they create for participants. Sometimes institutions work well enough, but we use the word “politics” for efforts to fix them. Political action is driven by a belief that the structure and incentives of existing institutions demands change.
  2. “Politics as conflict”: Here the idea is that different people have different interests and ideals, so it matters who’s in charge. Politics is mostly about putting one’s own side in control of institutions.

Alexander’s post is long and I could argue that it’s a bit tilted in favor of #1, partly because the examples he cites of #2 are unnecessarily tendentious, e.g., a Baffler article on James Buchanan. Very serious people from a range of perspectives agree with #2. Still, even with a possible tilt, I find Alexander’s framework useful.

The poster child for #1 would be China. The Communist Party took control in 1949, representing a demographic group (workers and peasants) and an ideology (state communism). A fairly continuous group of leaders still runs that Party and that country. For instance, the current premier, Xi Jinping, is the son of the Party’s former propaganda chief, vice-premier, and National People’s Congress vice chair (1952-62). But the regime has shifted from radically egalitarian to rapaciously capitalist, and many grandchildren of Red revolutionaries are billionaires. I make sense of this story by discounting politics as conflict. It doesn’t matter who runs the government or what they stand for. Structures and incentives ultimately prevail. If single-party government gives the ruling cadre a chance to rack up billions, they will sooner or later rack up billions.

Roberto Mangabeira Unger has unimpeachable leftist credentials, but he faults the 20th century left for ignoring institutional structures and the incentives they create. “With few exceptions (such as the Yugoslav innovations),” he writes, “the radical left … has produced only one innovative institutional conception, the idea of the soviet or conciliar type of organization: that is to say, direct territorial and enterprise democracy.” But soviets were never seriously developed to address “practical problems of administrative and economic management,” and they have “quickly given way to forms of despotic government” (False Necessity, pp. 24-5).

On the other hand, politics as conflict (#2) makes better sense of “realignment” elections in functional democracies. When FDR won the presidency in 1932, or when the British Labour Party won in 1945, new people with new interests and new ideas took over those countries. The result was a raft of new policies and institutions. When Thatcher and Reagan won elections decades later, they reversed some of those policies and began to dismantle some of those institutions. It matters who wins the support of the majority of voters and what program they propose.

The same debate also arises in specific domains of policy. For example, people who believe in politics as conflict think that the key questions for education are what is taught and how. There are lively debates between whole language and phonics, patriotic and critical versions of American history, STEM and the humanities. To influence the outcome of these debates, we can try to persuade teachers and schools to adopt our vision of education. We can also enact favorable policies, such as legislative mandates to teach or assess in certain ways.

Meanwhile, some people believe that the important questions in education concern structures and incentives. Maybe we must pay teachers more and protect their autonomy, or assess student outcomes and hold teachers accountable, or give parents choice and let dollars flow to the schools that they choose. These are politically and ideological contrasting theses, but all presume that the way to improve education is to get the incentives right.

It’s too easy to say, but I believe it: politics is both institutional design and conflict over ideas and interests, and each aspect requires attention. Unger recommends that reformers “develop elaborate institutional incentives, a strategy for putting them into effect, and a view of social transformation to inform both their programmatic and their strategic ideas. They must also redefine their guiding ideals and their conceptions of the relation of these ideals to the aims of their political opponents. For if the real meaning of an ideal depends upon its tacit institutional background, a shift in the latter is sure to disturb the former” (pp. 20-21).

It’s a mistake to ignore incentives and assume that institutions will do what they officially promise, unless that somehow pays off for the people in charge. To assume that public schools will serve every child is like assuming a can-opener on a desert island. (Or assuming that a dictatorial party will pursue equality just because it calls itself “communist.”) But it’s also a mistake to discount ideas and ideals or to presume that the only payoffs that people care about are monetary. For the purpose of explaining social change, both incentives and ideals have power.

Further, if you want to know whether you are changing the world for the better, you must rely on a range of evidence. It’s useful to observe people’s behavior under constraints. For example, price signals tell you what people value, given what they have. That kind of analysis falls under Alexander’s “politics as mistake” heading (although the word “mistake” is a bit misleading; it’s really politics as engineering). However, evidence from behavior is always insufficient, because you must also decide what means and ends are good. Unless you arrogantly assume that you can answer that question by yourself, you must listen to other perspectives. And that necessitates “politics as conflict.”
