As the long-running debate continues over whether childhood vaccines cause autism, Yale professor Dan M. Kahan (who has appeared on Freakonomics Radio) takes a look at people’s attitudes toward vaccination. He dispels the myth that liberals are more likely to be anti-vaccine. From the abstract of his new paper:

This Report presents empirical evidence relevant to assessing the claim — reported widely in the media and other sources — that the public is growing increasingly anxious about the safety of childhood vaccinations. Based on survey and experimental methods (N = 2,316), the Report presents two principal findings: first, that vaccine risks are neither a matter of concern for the vast majority of the public nor an issue of contention among recognizable demographic, political, or cultural subgroups; and second, that ad hoc forms of risk communication that assert there is mounting resistance to childhood immunizations themselves pose a risk of creating misimpressions and arousing sensibilities that could culturally polarize the public and diminish motivation to cooperate with universal vaccination programs. Based on these findings the Report recommends that government agencies, public health professionals, and other constituents of the public health establishment (1) promote the use of valid and appropriately focused empirical methods for investigating vaccine-risk perceptions and formulating responsive risk communication strategies; (2) discourage ad hoc risk communication based on impressionistic or psychometrically invalid alternatives to these methods; (3) publicize the persistently high rates of childhood vaccination and high levels of public support for universal immunization in the U.S.; and (4) correct ad hoc communicators who misrepresent U.S. vaccination coverage and its relationship to the incidence of childhood diseases.
Liberals, according to a new paper in the Journal of Wine Economics by Pavel A. Yakovlev and Walter P. Guessford of Duquesne University. The paper, “Alcohol Consumption and Political Ideology: What’s Party Got to Do with It?,” looks at alcohol consumption and voting patterns from 1952 to 2010 and finds that as states become more liberal politically, they drink more beer and spirits, although less wine. The abstract:
Recent research in psychology and sociology has established a connection between political beliefs and unhealthy behaviors such as excessive alcohol, tobacco, and illegal drug consumption. In this study, we estimate the relationship between political ideology and the demand for beer, wine, and spirits using a longitudinal panel of fifty U.S. states from 1952 to 2010. Controlling for various socioeconomic factors and unobserved heterogeneity, we find that when a state becomes more liberal politically, its consumption of beer and spirits rises, while its consumption of wine may fall. Our findings suggest that political beliefs are correlated with the demand for alcohol.

There’s a new political party in town: it’s primarily focused on creating more political parties. Jared Hardy recently wrote to us about Startup Party USA, the “first 3+ political party in the United States. From the website:
Tired of only voting for a party duopoly? Join the Startup Party USA to change our elections away from duopolist rule. Startups aren’t just for monetary profit.
The Startup Party USA intends to be the first 3+ political party in the United States. A 3+ political party is one with the primary mission of reforming voting rules so that even more parties have an equal and fair chance at winning elections. To accomplish this, we must first eliminate winner-take-all or “first past the post” voting everywhere in the USA.
A new study by Bradley W. Lane, Natalie Messer-Betts, Devin Hartmann, Sanya Carley, Rachel M. Krause, and John D. Graham on why governments promote electric vehicles finds that the environmental benefits of the vehicles have little to do with politicians’ motives for supporting the industry. Perhaps not surprisingly, “Government Promotion of the Electric Car: Risk Management or Industrial Policy?” (gated) finds that the economic benefits of the industry are the primary motivator for most governments. From the press release:
Contrary to common belief, many of the world’s most powerful nations promote the manufacture and sale of electric vehicles primarily for reasons of economic development – notably job creation – not because of their potential to improve the environment through decreased air pollution and oil consumption.
This is among the main findings of a study by researchers at the Indiana University Bloomington School of Public and Environmental (SPEA) and University of Kansas that analyzed policies related to electric vehicles (EVs) in California, China, the European Union, France, Germany, and the United States – political jurisdictions with significant automotive industries and markets for EVs.
“Billions of dollars are being invested despite doubts that some express about the viability of electricity as a propulsion system,” said John D. Graham, SPEA dean and co-author of the study. “The objective of many of these national and sub-national governments is to establish a significant position – or even dominance – in the global marketplace for these emerging, innovative new technologies.”
How illiterate do our politicians think we are?
In the old days we had plain titles of laws, such as the Voting Rights Act or the Civil Rights Act. In the United Kingdom, the titles of laws still reflect their subjects, whether the Official Secrets Act or the National Health Service Act. The modern U.S. Congress, as the least trusted institution in America, is particularly prone to these propaganda titles. Thus, modern Americans, instead of universal, government-funded healthcare, get government-funded propaganda: the Patient Protection and Affordable Care Act. Read More »
Our podcast “The Truth Is Out There…Isn’t It?” showed that even very smart people can fool themselves into confirming their own beliefs, especially when surrounded by peers with the same beliefs. PSMag.com reports on new research that shows young Americans self-identify as more conservative than they actually are:

“Commentators have presumed that America is a ‘center-right’ nation,” write psychologists Ethan Zell of the University of North Carolina-Greensboro and Michael Bernstein of Pennsylvania State University-Abington. “The present findings challenge this assumption.”
Their three surveys featured, respectively, 199 students at a Southeastern university, 360 adults recruited on Amazon’s Mechanical Turk (with a mean age of 28), and 154 students from two universities. The final group was weighted so that there were an equal number of people in each of seven political categories, ranging from very liberal to very conservative.
In each case, participants revealed how they define themselves politically on that seven-point scale. They then completed a quiz developed by the Pew Research Center for the PBS Newshour, in which they indicated their views on 12 major issues, including welfare and gay marriage.
Results were consistent across the board: Participants rated themselves as more conservative than their positions on the issues would indicate.
We’ve written in the past about how weather can have a surprisingly strong effect on things like civil war and riots. (Short story: rioters don’t like getting rained on and droughts can start a war.)
The political scientist Peter Kurrild-Klitgaard has a new paper on the topic in Public Choice (abstract; PDF) called “It’s the Weather, Stupid! Individual Participation in Collective May Day Demonstrations.” The bolding is mine:
“We investigate the possible explanations for variations in aggregate levels of participation in large-scale political demonstrations. A simple public choice inspired model is applied to data derived from the annual May Day demonstrations of the Danish labor movement and socialist parties taking place in Copenhagen in the period 1980–2011. The most important explanatory variables are variations in the weather conditions and consumer confidence, while political and socio-economic conditions exhibit no robust effects. As such accidental or non-political factors may be much more important for collective political action than usually acknowledged and possibly make changes in aggregate levels of political support seem erratic and unpredictable.”
