Would Clinton have defeated Trump in an epistocracy?

[Update (April 2017): Now that data from the 2016 American National Election Studies have been released, it seems likely that my conclusions in this post are wrong. You can find the details in my new post.]

The big story of the 2016 presidential election is that Trump appears to have won an unprecedented share of whites without college degrees, especially men. According to the exit polls, Trump had a 49 point advantage over Clinton among non-degreed white men, compared with a 31 point advantage for Romney in 2012 and a 20 point advantage for McCain in 2008. Trump also performed relatively well with non-degreed white women. McCain won them by 17 points, Romney by 20, and Trump by 28. (These shifts relate to Trump’s white nationalist priorities, something that appealed to the self-interest of less-educated whites.)

Pre-election polls had suggested a smaller Trumpward shift among non-degreed whites that would be more than offset by a large Democratic shift among degreed whites. In fact, it turned out that pre-election polls had badly overestimated Clinton’s performance with white voters across the board. Non-degreed whites shifted to Trump (bigly), while whites with college degrees ended up pretty close to where they were in 2008—Trump had a 15 point advantage with degreed white men while Clinton had a 6 point advantage with degreed white women, margins very similar to the McCain/Obama race (though better for Democrats than the Romney/Obama race). Further, there doesn’t appear to have been a non-white shift to overcome Trump’s gains with non-degreed whites. While non-whites seem, in line with expectations, to have been a greater share of the electorate this time around, the exit polls suggest that their preference for Clinton (by 53 points) didn’t match their previous preference for Obama (by just over 60 points).

Thus, it appears, Trump’s success with less-educated whites (and the absence any major offsetting movement from other groups) was the demographic key, particularly helping him in Rust Belt states and rural areas.

For those who are disappointed by this result, it might be tempting to start considering libertarian epistocracy proposals. Epistocracy means, literally, having the knowledgeable (epist) run things (ocracy). The basic idea is that, one way or another, the votes of those who know the most ought to count the most.

The clearest recent statements on epistocracy have come from philosopher Jason Brennan (with related suggestions from economist Bryan Caplan, e.g., here and in his earlier book, discussed critically here). In a recent essay, Brennan explains: “Epistocracy comes in many forms. An epistocracy might give everyone one vote, then grant extra votes to citizens who pass a test of basic political knowledge (such as the citizenship exam). Or it might grant the right to vote only to citizens who pass such a test. Or it might instead hold an ‘enfranchisement lottery’: Immediately before an election, choose 10,000 citizens at random, and then those citizens, and only those, are permitted to vote, but only if they first complete a competence-building exercise. Or, an epistocracy might govern through what I call a ‘simulated oracle’ [i.e., a complex statistical procedure that would attempt to translate low-knowledge voting into high-knowledge preferences].”

How might such proposals have affected the 2016 presidential election?

Clinton/Trump under some epistocratic alternatives

Below I provide estimates of the popular vote margin and demographic representation of the electorate under a few epistocratic scenarios—scenarios where voting power is adjusted in various ways using a political-knowledge test. I don’t know of any publicly available data that shows political knowledge in relation to 2016 voting, so I used the 2012 American National Election Studies (ANES) to gauge political knowledge, and then used that information to adjust the 2016 exit poll results. The 2012 ANES included 11 political knowledge items of the sort Brennan and Caplan discuss, including things such as knowing basic economic facts, knowing the party controlling the House and Senate, and recognizing major political figures. I used the results to create demographic-and-party-specific estimates of voters’ political-knowledge test performance (e.g., I looked at how white women with degrees who identify as Democrats perform, how white women with degrees who identify as Republicans perform, how white men without degrees who identify as Democrats perform, and so on).

The epistocratic scenarios that I modeled involve either penalizing especially low-knowledge voters (i.e., those who got fewer than 5 items correct on the 11-item test) or rewarding especially high-knowledge voters (i.e., those who got 9 or more correct). I also tried a graduated scenario in which those with fewer than 5 correct responses got 1 vote, those with 5 or 6 correct responses got 2 votes, those with 7 or 8 got 3 votes, and those with 9 or more got 4 votes.

The chart below shows the results. The first outcome is simply the 2016 exit polls without any adjustment. While exit polls often get a bad rap, and probably do badly miss some specific groups either in terms of turnout or voting preferences, this year they ended up giving a fairly accurate read of the actual popular vote margin as a whole, showing Clinton with a small advantage over Trump. In fact, the best information on actual votes at the time I’m writing this is that Clinton has 47.7% of the popular vote compared with Trump’s 47.1%—a 0.6 point advantage for Clinton—which is almost exactly what the exit polls showed. The actual vote totals will likely further shift in Clinton’s direction as some still-uncounted votes become counted (including, e.g., some West Coast absentee ballots), but won’t shift by all that much at this point.

Next on the chart are the various epistocratic scenarios. What if we give especially low-knowledge voters only half a vote, or only a third, or bar them completely? What if we use a graduated more-votes-for-more-knowledge system? What if we give especially high-knowledge voters an extra vote, or two, or take epistocracy literally and allow only these high-knowledge folks to vote?

Do any of these proposals improve Clinton’s popular vote margin over Trump? No. In fact, each one would have given Trump a popular vote lead, anywhere from 0.5 points (giving high-knowledge folks a single extra vote) to 4.3 points (letting only high-knowledge folks vote). In an epistocracy of the sort Brennan and others imagine, Trump’s victory over Clinton would have been even more securely won.

epistocracy2016

Well that’s (actually not) surprising

I know that many of my high-education compadres will think these results are madness. Surely, many believe, the smartest people are mostly Democrats. But it’s really complicated.

The Democratic coalition actually combines many who have the highest average political knowledge (e.g., Ivy Leaguers and folks with postgraduate degrees) with many who have the lowest average political knowledge (e.g., non-whites without college degrees). And, moreover, the most solid Democratic support often comes from the low-performing part of the coalition—so, for example, the exit polls show Clinton winning voters (of all races) with postgraduate degrees by 21 points, but this is dwarfed by her 55 point win with non-degreed non-whites. The reality is that anything that lowers the voting impact of less-educated non-whites is particularly detrimental to Democratic margins—including various well-known current Republican efforts (voter ID requirements, voter purges, felon bans, reducing the number of polling locations in minority neighborhoods, gerrymandering to further concentrate minority votes, and so on) and also including many libertarian epistocracy proposals.

Also, the role of political knowledge can vary from group to group. So, for example, within college-educated whites, higher political knowledge is associated with less Republican support. But within non-college whites, higher political knowledge predicts more Republican support. Among non-whites, voters with high political knowledge support Democrats by lower margins than voters with low political knowledge. Again, it’s really complicated.

Further, political knowledge—as measured by the standard kinds of questions—relates strongly to education, but is also substantially higher among older folks, whites, and men. So, for example, while the exit polls show somewhat more white women than white men turning out to vote (the top outcome on the chart), a scenario in which only high-knowledge folks vote (the bottom outcome on the chart) would be one in which men constitute almost 6 in 10 white voters. Given that white men were well more likely to vote for Trump than white women, this kind of epistocratic gender skew would be a real contributor to increasing Trump’s popular vote margin. (As a reminder, the exit polls had Trump winning degreed white men—the key beneficiaries of epistocracy—by 15 points, 54 to 39.)

The reality of epistocracy

No, epistocracy would not have prevented Trump from defeating Clinton. In fact, primarily by making the vote whiter and more male, it would have given him the popular vote to go with his Electoral College victory. (Having said that, it’s certainly possible that some epistocratic proposals could have prevented Trump’s Republican nomination in the first place. I’ll leave that analysis to others.)

Keep in mind that we already live in a kind of epistocracy. First, political knowledge is strongly associated with the propensity to vote. So, in the 2012 ANES sample, only 59% reported voting among those getting fewer than 5 of the 11 political knowledge questions correct, rising to 76% of those answering 5 or 6 correctly, 88% of those answering 7 or 8 correctly, and 93% of those answering 9 or more correctly. In addition, our governmental decision-makers (including elected representatives, cabinet members, high-level bureaucrats, judges, and so on) have, on average, very high levels of political knowledge. And they have rather oversized numbers from demographics associated with high-knowledge voters—college-educated, older, white, and male.

These sorts of patterns already result in a number of policy realities that are more libertarian-leaning than the general public would prefer (including lower taxes on the wealthy and stingier spending, but also fewer restrictions on abortion, more immigration, and more vigilance against group-based discrimination). But I understand why solid libertarians don’t think this goes far enough and would prefer some form of intervention to further increase the influence of libertarian demographics. Just as I understand why solid liberals who understand the effects of epistocracy proposals will oppose them. Most people have results-oriented political minds, after all.

A look at the preliminary 2016 exit polls

So what the hell happened last night? While the 2016 presidential exit polls were conducted in only a limited number of states, and while the full sample has yet to be made public, we can still find clues in the vote margins within various demographic groups.

The chart below contains the major groups that favored Trump. The bars show the Trump-minus-Clinton net exit poll advantage. The Trump coalition primarily included white religious conservatives and whites (especially men) without college degrees. These groups overlap considerably, given that low-education folks are substantially more likely to identify as “evangelical” Christians than high-education folks. But, still, though the exit polls don’t show it directly, it’s safe to assume that, e.g., non-college white men who aren’t Christian were substantially less likely than white evangelicals to support Trump (though they might have still favored him to some degree, something that will take more data to sort out).

trumpvoters

The key groups in the Clinton coalition are in the next chart, showing the Clinton-minus-Trump net exit poll advantage. It’s mainly people who worry about various forms of discrimination: Racial minorities, LGBT folks, people who are not Christian, and immigrants. The most-educated folks are here as well, though we don’t yet know what the white vs. non-white breakdown is (though the large majority of people with postgrad degrees are white).

clintonvoters

But how does this differ from other recent elections?

The Trump and Clinton voting groups are broadly familiar from other recent elections. It’s been true for a while that white evangelicals and non-college white men tend to support Republicans, and that racial minorities and non-Christians tend to support Democrats. But the exit polls are suggesting that this election had some pretty major shifts.

The big one is white men without college degrees. In 2008, McCain won them by 20 points; Romney increased this margin to 31 points in 2012. And Trump: 49 points. We’ll see if the full exit polls and other data sources confirm a margin in this range. But, if so, that’s most of the answer to how Trump pulled off his upset victory.

Trump also did substantially better than other recent Republicans with groups that are related to non-college white men, including unmarried men (Obama won them by around 18 points in 2008 and 2012, but the current exit polls show Clinton with only a 1 point advantage), people with incomes under $50k (Obama won them by 22 points, while Clinton won them by only 11), and union households (Obama won them by around 19 points, while Clinton won them by only 8).

Clinton picked up a bit of support within certain groups as well, just nothing close to Trump’s gains with non-college white men. The clearest advance was with LGBT folks. Obama won them by 43 in 2008, and then by 54 in 2012. The 2016 exit polls so far show Clinton with a 64 point advantage. Clinton also appears to have made marginal gains with married women. They supported McCain by 4 and Romney by 7, but then Clinton by 2. Then there were some Clinton shifts that were bigger deals comparing 2016 to 2012, but not big deals comparing 2016 to 2008. For example, white women with degrees went for Clinton by 6 after going for Romney by 6 in 2012, yet also went for Obama by 5 in 2008. Similarly, people with incomes above $100k went for Trump by only 1 after favoring Romney by 10 in 2012, yet this group was evenly split in 2008.

Notice that this election appears to have had a substantially weaker—though not eliminated—link between income and party vote. Poorer folks still favored the Democrat while richer folks favored the Republican, but the large 2012 gap was replaced by a much lower 2016 gap. This is due, of course, to Trump’s enhanced performance with non-college whites while Clinton retained non-whites, which scrambled the income-based vote. (I discussed how trends like this might end up changing the long-term party coalitions in the concluding section of a previous post on libertarian demographics.)

So why did we see big shifts with non-college white men? Rob Kurzban and I have a new essay on the Washington Post’s In Theory blog, where we echo some of the findings from our book that are sure to make everyone unhappy: Mainly, these Trump voters have self-interested reasons to favor group-based discrimination, and, finally having been given a candidate who squarely agrees with them, they supported him.

The demographics of Republicans and Democrats

There’s talk about how voters seem to be “coming home” at this stage in the 2016 presidential race, with both candidates solidifying support from their party identifiers. This post is a reminder of who these Republican and Democratic identifiers are. Using Pew political surveys of people registered to vote from the period between the 2012 election and the 2016 primaries (N = 48,160), here’s the basic demographic breakdown of the pre-2016 party coalitions.

Republican-leaning groups (shown in the chart below) are dominated by white Christians, especially those who are self-identified evangelicals, have higher incomes, attend church regularly, don’t have graduate degrees, and are male.

repgroups(Note: “Evangelical” includes non-Catholic Christians who self-identify as “born again or evangelical” and Mormons.)

The Democratic coalition, in contrast, primarily includes racial minorities and non-Christians (and also non-heterosexuals, information not usually available in Pew data, but something that shows up clearly when it is), especially women and those with more education. Also skewing Democratic are non-evangelical Christian women with low incomes and non-evangelical Christians with graduate degrees.

demgroups

Some often-discussed demographic items don’t show up as major points of division. Age, for example, isn’t a very big deal in party identification once you’ve taken into account that younger voters are more likely to be racial minorities and less likely to be Christians. Similarly, the urban/rural and coastal/southern divides are in large part a function of their residents’ contrasting racial and religious profiles.

A deeper dive into partisan demographics requires keeping in mind how bits of information overlap. Some examples: Minorities tend to be poorer and less educated than whites. People with more education and married people tend to be richer. Single women tend to be poorer than single men. Evangelicals tend to be less educated and to go to church more. Blacks are more likely to be evangelicals and less likely to be married. When Hispanics and Asians are Protestants, they’re less likely to be immigrants. And so on. It’s complicated stuff.

One of the overarching patterns that’s often confusing involves socioeconomic status. In short, especially among whites, people with higher incomes skew to the right while people with higher education skew to the left. The trick is that the two patterns are driven by different kinds of issues. Those with higher incomes tend to be more conservative specifically on redistributive economic issues. Those with higher education tend to be more liberal primarily on issues of discrimination as well as on abortion.

Another common source of confusion is the “what’s the matter with Kansas” thing, claiming that downscale whites ignore their economic interests. It’s a story that’s just not true. The fact is that white Christians with lower incomes have long been less likely to support Republicans than those with higher incomes. If you’re looking for people who tend to ignore their incomes when voting these days, you should be looking at core Democratic groups, particularly at blacks and degreed non-Christians. A deeper problem with the Kansas frame is that it equates one piece of the self-interest pie—policies involving income redistribution—with the whole pie. People also have self-interest in issues of discrimination and meritocracy (and, indeed, the Democratic coalition seems to be primarily driven by these interests) as well as with sexual and reproductive lifestyle issues like abortion. Sometimes one set of issues tends to dominate a group’s partisan leanings (e.g., issues of race for black voters) and sometimes groups are best understood as essentially averaging across their issue interests (e.g., white Christians).

What’s changing this year?

The details of party coalitions are always evolving. For example, the strong Democratic advantage among the most-educated folks is a pretty recent development, having become a big deal only since around 2004. In a related vein, the pre-election polls this year suggest that Clinton might perform substantially better with college-educated whites than Obama did.

In general, we could see new patterns in this election from at least four sources: (1) Cohort replacement, as older, whiter, more religious, less educated generations are being replaced by more diverse youngsters. (2) Some groups might be relatively more likely to have changed their party identifications in response to the current race. (3) Some groups might be relatively more likely to not vote in line with their party identifications in the current race. And (4) some groups might be relatively more likely or unlikely to turn out to vote this time around. With college-educated whites, for example, some of Clinton’s increased margin in pre-election polls could be from cohort replacement (e.g., the younger folks are less religious), some from party-switching, some from outside-their-usual-party voting, and some from changes in turnout intentions (affecting their inclusion in reports on “likely voters”).

In fact, any changes this year in the demographics of party identification are likely to be subtle, requiring lots of data and time to determine definitively whether any apparent shifts are real. As for the outcome of the current election, its main determinant will likely be—as usual—varying turnout among demographic groups whose preferences were largely predictable months (and even years) ago.
