In a recent article, Thomas Edsall gave a graph showing that the percentage of people saying that religion was losing influence had increased substantially between 2012 and 2014. I thought that the question went farther back than that, so I searched for it. I got more than I bargained for, because it was asked no less than 78 times between 1957 and 2014, first by Gallup, which still asks it from time to time, and then by other organizations, notably Pew. The exact question is: "At the present time, do you think religion as a whole is increasing its influence on American life or losing its influence?" Sometimes people volunteered that it was staying the same, or some other intermediate answer like "some of both," but those number varied widely (from 1% to 17%), so I think that organizations must have differed in the extent to which they pressed for an answer. To take them out of the picture, I took the odds of "increasing" to "losing." For example, the last time it was asked, 22% said increasing and 72% said losing, for odds of about 1:3.3. Here are the results over time (shown on a log scale):
There are a couple of obvious changes: a big shift towards "losing influence" in the 1960s and a large but short-lived shift towards "increasing influence" after 9/11. But there are also several other shifts that took place over a substantial period of time: towards "losing influence" from the mid-1980s to the early/mid 1990s, then back towards "increasing influence until about 2000, then towards "losing influence" since 2002. I can't think of a plausible reason for them: they don't seem to follow the political climate, or trends in things that people might think of as moral problems like the crime rate or divorce. But given the amount of data here, they're not just chance variation.

Serious sociology
This is a follow-up to my post of a couple of weeks ago. In the general media, I've encountered a lot of claims that educational mobility is declining--that it's become less common for children of parents with little education to move "up" or children of parents with lots of education to move "down".* Although I'm reasonably familiar with the scholarly literature on occupational and income mobility, I don't know of anything on educational mobility, and a search of Google Scholar didn't come up with anything very promising.
So I did a basic analysis using the General Social Survey, which asked people how much schooling they had, and also how much their father had. I made a tables of father's education by own education for six groups: born in 1909 or before, born 1910-19, 1920-29, 1930-54, 1955-69, and 1970-90. Both were classified into seven categories: 6th grade or less, 7th or 8th grade, some high school, high school graduate, some college, college graduate, and graduate education. I restricted this to white men because it seems pretty likely that the trends will be different for women and non-white men, and to people age 25 or over because many of those below that age are still in school.
I fit a model that described the changes with a single number representing the difference from the last cohort. The number represents the association between father's and son's education, so high numbers mean less mobility. Here are the results as a figure:
The conventional wisdom seems to be right: the association is substantially higher in the last generation (people born 1970-90), although there was some upward trend before then. The scale of the vertical axis isn't meaningful, but in a rough way you could say the association is about twice as strong in the youngest cohort as in the oldest.
*I mean those in relative terms--how much education a person has relative to what other people in their generation has. In an absolute sense, upward movement has been much more common, because average levels of education rose from generation to generation until the 1970s.

Caring about college
Scott Walker, an all-but-declared candidate for the Republican presidential nomination, didn't graduate from college. That's unusual--as far as I know, the last "major" candidate for president without a college degree was Paul Simon, who sought the Democratic nomination in 1988. Ted Cruz, a declared candidate for the Republican presidential nomination, got an undergraduate degree from Princeton and a law degree from Harvard. That's not unusual--George W Bush had degrees from Yale and Harvard. But most Republicans with degrees from elite schools have downplayed them--Bush talked about Midland, Texas, a lot more than he did about Harvard or Yale-- while Cruz has made them a central part of his story.
Do voters care about this sort of thing? A 2007 Pew survey asked respondents if they would be more or less likely to vote for a candidate with various characteristics. One was "attended a prestigious university such as Harvard or Yale," and another was "did not attend college." People were split on a candidate who hadn't attended college: 49% said it would make no difference and 47% said they'd be less likely to support the candidate (only 3% said they would be more likely to). Most people (74%) said that attending a prestigious college wouldn't make any difference; 20% said more likely and only 5% less likely.
A common perception is that liberals value educational credentials, while conservatives are less interested, or maybe even hostile. In fact, that was why I started thinking about the issue: would Cruz's association with elite colleges hurt him with "the base"? According to these questions, there might be some difference in the expected direction, but it's small, Another potential influence is education: you could make arguments for an effect in either direction. It turns out that, less educated people may be a little more likely to say that not attending college wouldn't matter; education has no clear effect on views about having attended a prestigious university.
I had no reason to expect gender to make any difference, but since nothing very interesting was going on, why not try? Gender didn't make much difference for reaction to a candidate who hadn't attended college, but made a substantial difference for reactions to one who attended a prestigious university: 8% of men, and only 2% of women, said they would be less likely to support one. To put it another way, more than three-quarters (60 out of 79) of the people who said they would be less likely to support the candidate were men.
Even among men, attending a prestigious university was much more likely to be a plus than a minus, but the gender difference needs an explanation. My thought is that a "man of action, not words" image has appeal to some men, and there's no real parallel to that image for women.

Forgotten Beauty
In March 1951, the Gallup Poll had a question in which they gave people a picture (at that time, the polls were done in person rather than over the phone) and said: "Here are pictures of six different girls all dressed alike. I'd like you to look at each one and tell me which ONE you think is most beautiful." #4 was the most popular choice with about 57%, followed by #3 and #5 with about 15% each. The others were at 5% or less.
Preference varied by education: #4 was uniformly popular in all groups, but #3 was the choice of less than 10% of the people with a grade school education and 28% of the college graduates, while #5 was the choice of more than 20% of those with a grade school education and only 5% of the college graduates. There were similar, although less dramatic, differences by occupation and economic level: #3 got more support in the "higher" groups and #5 got more support in the lower. There were also big differences by race: among blacks, #5 led #3 by about 30%-8%; among whites #3 led by about 16%-13%,
There were no gender differences in preferences for #3, but compared to men, women were more likely to prefer #4 and less likely to prefer #5. Older people were less likely to prefer #3, but only a little more likely to prefer #5--they were more likely to prefer #1 and #2 (age was the only factor that had a clear connection to preferences for #1 and #2).
At this point, I should show the picture, but I don't have a copy and have never seen it. It's not included in the documentation at the Roper Center. The Gallup Poll used to have a newspaper column in which they highlighted findings from their polls, but I did a search and couldn't find it there. The question is prefaced with "we have been asked to find out", which suggests they did it for some client. Maybe it was a magazine that published an article about the poll, but if so I haven't found it. Or maybe it was a commercial client (they occasionally put "market research" questions in their regular polls), in which case it's probably lost for good.
In conclusion, there seems to be something interesting going on, but I have no idea what it is, and little hope of ever finding out.

If you're so smart.....
In a review of Robert Putnam's new book, Jason DeParle (a reporter for the New York Times) says "where Putnam succeeds is in describing the diverging life chances of children in rich and poor families. ('Rich' parents finished college; 'poor' parents have high school degrees or less.) " Of course, education is not really equivalent to riches, as many adjunct professors could tell you, but this led me to wonder exactly how much overlap there is the incomes of different educational groups.
It's easy to find statistics on differences in average income by education, but harder to find information on the whole distribution. Here is a table, which I made from Bureau of Labor Statistics data on "usual weekly earnings of full-time wage and salary workers."
Percentiles
10th 25th 50th 75th 90th
Not HS Grad 301 374 488 657 887
HS Grad 367 482 668 960 1355
Some College 398 532 761 1111 1560
Bachelor's 529 744 1101 1647 2368
Advanced Degree 588 953 1386 2009 2974
Education raises the "ceiling" more than the "floor"--the 10th percentile for people with an advanced degree is less than twice the 10th percentile of people who aren't high school graduates, while the 90th percentile is about 3.3 times as high. You can get a sense of the overlap by comparing percentiles--for example, someone who's at the 90th percentile for those who aren't high school graduates would be well below the median for people with a bachelor's degree.
For a more detailed comparison, I assumed that earnings followed a log-normal distribution (which is usually approximately true except in the highest levels) and estimated the mean and standard deviation from the data above. The resulting distributions are shown in this figure (I scaled it up to earnings per year):
The figure makes it clear that people without a high school degree have little chance of being rich, or even affluent. People with just a high school degree, however, have a reasonable chance to make it to the upper middle class.

Fifty years
During the 1930s and 1940s, Fortune magazine sponsored a series of surveys conducted by the Roper Organization. It was probably the most important early series after the Gallup Poll. Unfortunately it stopped in 1949--the Roper Organization continued, but most of the questions were never repeated. However, in 1990 Fortune sponsored a survey that replicated some questions from 1939 and 1940.
"Do you think your son's or daughters opportunities to get ahead will be better than, or not as good as those you have" [or "If you had children," etc.]
1939 1990
Better 61% 68%
Not as good 14% 20%
Same 10% 6%
Not comparable 2% 2%
DK 12% 4%
Do you think the years ahead seem to hold, for you personally, a good chance for advancement or the probability of no improvement over your present situation?
Advancement 56% 64%
No improvement 33% 30%
DK 10% 6%
Do you believe that the great age of economic expansion and opportunity in the US is over or that American industry can create comparable expansion and opportunity in the future?
Over 13% 16%
Comparable 72% 78%
DK 15% 6%
Putting them together, optimism about the future remained about the same.
Do you think your opportunities to succeed are better than or not as good as your father had?
Better 61% 79%
Not as good 20% 13%
Same 12% 6%
Not comparable 3% 1%
DK 5% 1%
People in 1990 were more likely to see improvement, although at both times most people were favorable.
Turning to economics,
Do you believe that a high tariff to keep out foreign goods in competition with American goods is a good policy or a bad policy?
Good 59% 47%
Bad 14% 37%
Depends 11% 9%
DK 15% 7%
A substantial shift towards support for free trade, although tariffs were still more popular.
Do you think the interest of employees and employers are, by their very nature opposed or are they basically the same?
Opposed 24% 43%
Same 56% 24%
DK 19% 14%
A big change, and one that is the opposite to a what is sometimes said.
Suppose it became necessary to increase taxes, which one or two of these methods would you most prefer?
Extend income tax 17% x
Raise income tax 14% 5%
Corporate profits 21% 41%
Sin & luxury 41% 47%
Federal sales tax 14% 17%
DK 12% 7%
"Extend" means making more people liable to pay income tax (they had a fairly long description, which I won't quote). That option wasn't offered in 1990, presumably because the share of people who had to pay income tax had increased a lot. The big change was an increase in the share who favored increasing taxes on corporate profits. Like the previous question, it suggests an increase in anti-business sentiment.
It's interesting to think that 1990 was 25 years ago. I hope Fortune will do a 75th anniversary follow-up.

Good principle, bad example
The New York Times had an interview with Alan Krueger and Austen Goolsbee, chairmen of the Council of Economic Advisors in the first Obama administration, about the bailout of the auto industry. The bailout was unpopular at the time but seems to have worked out pretty well. When asked if it was was likely to be an issue in the 2016 election, Goolsbee said no: "when things work out, there’s a tendency toward revisionism. Didn’t Nixon get only 20 percent of the vote in 1972 according to the polling in 1975?" Did he? I looked for surveys from 1975 that asked about vote in 1972, but found only one, so I broadened the search to include 1976. The results:
Nixon McGovern Other Don't Remember
GSS (Feb 1975) 60% 35% 3% 2%
GSS (Feb 1976) 58% 36% 3% 2%
CBS/NYT (3/76) 57% 39% 3% 2%
CBS/NYT (4/76) 57% 37% 2% 3%
The actual vote shares were 61% for Nixon, 38% for McGovern, and 2% for others. Although I'm sure Goolsbee is right about the general tendency, his example doesn't support him.
