Were Bush Tax Cut Supporters “Simply Ignorant?” A Second Look at Conservatives and Liberals in “Homer Gets a Tax Cut”

In a recent edition of Perspectives on Politics, Larry Bartels examines the high levels of support for tax cuts signed into law by President Bush in 2001. In so doing, he characterizes the opinions of “ordinary people” as being based on “simple-minded and sometimes misguided considerations of self interest” and concludes that “the strong plurality support for Bush’s tax cut...is entirely attributable to simple ignorance.” Our analysis of the same data reveals different results. We show that for a large and politically relevant class of respondents – people who describe themselves as “conservative” or “Republican” – increasing information levels increase support for the tax cuts to the extent that they have any affect at all. Indeed, using Bartels’ measure of political information, we show that the Republican respondents rated most informed supported the tax cuts at extraordinarily high levels (over 96%). For these citizens, Bartels’ claim that “better-informed respondents were much more likely to express negative views about the 2001 tax cut” is simply untrue. We then show that Bartels’ results depend on a very strong assumption about how information affects public opinion. He restricts all respondents -- whether liberal or conservative, Republican or Democrat – to respond to increasing information levels in identical ways. In other words, he assumes that if more information about the tax cut makes liberals less likely to support it, then conservatives must follow suit. This assumption is very presumptive about the policy and value trade- offs that different people should make. Our analysis, by contrast, allows people of different partisan or ideological identities to react to higher information levels in varying ways. This flexibility has many benefits, one of which is a direct test of Bartels’ restrictive assumption. We demonstrate that the assumption is untrue. Examined several ways, our findings suggest that much of the support for the tax cut was attributable to something other than “simple ignorance.” Bartels’ approach is based on a very strong presumption about how citizens should think and what they should think about. We advocate a different approach, one that takes questions of public policy seriously while respecting ideological and partisan differences in opinion and interest. Indeed, citizens have reasons for the opinions and interests they have. We may or may not agree with them. However, we, as social scientists, can contribute more by offering reliable explanations of these reasons than we can by judging them prematurely. By turning our attention to explaining differences of opinion, we can help to forge a stronger and more credible foundation for progress in meeting critical social needs.public opinion, tax policy, incomplete information, welfare economics

In a recent edition of Perspectives on Politics, Larry Bartels examines the high levels of support for tax cuts signed into law by President Bush in 2001. In so doing, he characterizes the opinions of “ordinary people” as lacking “a moral basis” and as being based on “simple-minded and sometimes misguided considerations of self interest.” He concludes that “the strong plurality support for Bush’s tax cut...is entirely attributable to simple ignorance.” Our analysis of the same data reveals different results. We show that for a large and politically relevant class of respondents – people who describe themselves as “conservative” or “Republican” – rising information levels increase support for the tax cuts.

A Dual Geometry of the Hadron in Dense Matter

We identify the dual geometry of the hadron phase of dense nuclear matter and investigate the confinement/deconfinement phase transition. We suggest that the low temperature phase of the RN black hole with the full backreaction of the bulk gauge field is described by the zero mass limit of the RN black hole with hard wall. We calculated the density dependence of critical temperature and found that the phase diagram closes. We also study the density dependence of the rho meson mass.Comment: 16 pages, 4 figures, typos corrected, references adde

Diffusion in an Expanding Plasma using AdS/CFT

We consider the diffusion of a non-relativistic heavy quark of fixed mass M, in a one-dimensionally expanding and strongly coupled plasma using the AdS/CFT duality. The Green's function constructed around a static string embedded in a background with a moving horizon, is identified with the noise correlation function in a Langevin approach. The (electric) noise decorrelation is of order 1/T(\tau) while the velocity de-correlation is of order MD(\tau)/T(\tau). For MD>1, the diffusion regime is segregated and the energy loss is Langevin-like. The time dependent diffusion constant D(\tau) asymptotes its adiabatic limit 2/\pi\sqrt{\lambda} T(\tau) when \tau/\tau_0=(1/3\eta_0\tau_0)^3 where \eta_0 is the drag coefficient at the initial proper time \tau_0.Comment: 19 pages, 2 figures, minor corrections, version to appear in JHE

Chiral Condensate in Holographic QCD with Baryon Density

We consider the chiral condensate in the baryonic dense medium using the generalized Sakai-Sugimoto model. It is defined as the vacuum expectation value of open Wilson line that is proposed to be calculated by use of the area of world-sheet instanton. We evaluate it in confined as well as deconfined phase. In both phases, the chiral condensate has a minimum as a function of baryon density. In the deconfined phase, taking into account the chiral symmetry restoration, we classify the behavior of chiral condensate into three types. One can set the parameter of the theory such that the results, in low but sufficiently higher density, is in agreement with the expectation from QCD.Comment: 23 pages, 8 figure

Neutrino Oscillations and Lepton Flavor Mixing

In view of the recent announcement on non-zero neutrino mass from Super-Kamiokande experiment, it would be very timely to investigate all the possible scenarios on masses and mixings of light neutrinos. Recently suggested mass matrix texture for the quark CKM mixing, which can be originated from the family permutation symmetry and its suitable breakings, is assumed for the neutrino mass matrix and determined by the four combinations of solar, atmospheric and LSND neutrino data and cosmological hot dark matter bound as input constraints. The charged-lepton mass matrix is assumed to be diagonal so that the neutrino mixing matrix can be identified directly as the lepton flavor mixing matrix and no CP invariance violation originates from the leptonic sector. The results favor hierarchical patterns for the neutrino masses, which follow from the case when either solar-atmospheric data or solar-HDM constraints are used.Comment: Latex, 9 page

Exploring the multi-humped fission barrier of 238U via sub-barrier photofission

The photofission cross-section of 238U was measured at sub-barrier energies as a function of the gamma-ray energy using, for the first time, a monochromatic, high-brilliance, Compton-backscattered gamma-ray beam. The experiment was performed at the High Intensity gamma-ray Source (HIgS) facility at beam energies between E=4.7 MeV and 6.0 MeV and with ~3% energy resolution. Indications of transmission resonances have been observed at gamma-ray beam energies of E=5.1 MeV and 5.6 MeV with moderate amplitudes. The triple-humped fission barrier parameters of 238U have been determined by fitting EMPIRE-3.1 nuclear reaction code calculations to the experimental photofission cross section.Comment: 5 pages, 3 figure
