PROBABILITY AND DEFEATERS

Abstract: Branden Fitelson and Elliott Sober raise several objections to my evolutionary argument against naturalism; I reply to four of them.     

The effect of self-affirmation on sexual prejudice

In three experiments, we explored the impact of a self-affirmation treatment on sexual prejudice (i.e., negative attitudes toward gays and lesbians). Studies 1 and 2 found that participants who were affirmed by valuing relationships with family and friends were significantly more prejudiced than participants who were affirmed by valuing other self-relevant characteristics. Relative to a non-affirmed control, the family/friends affirmation did not actually increase prejudice; however, other affirmations decreased bias. Study 3 replicated the finding that prejudice was higher among participants who affirmed to family/friends compared to those who affirmed to other values, and showed a mediator of the effect: the endorsement of traditional family values. That is, affirming to family/friends was associated with support for family values, which was positively associated with prejudice. These findings add to a growing body of evidence demonstrating the potential for self-affirmation to reduce bias, but establish that the type of value affirmed is an important consideration. Specifically, familial-based affirmations may undermine reduction of sexual prejudice because they remind individuals of values that many people see as being in conflict with expressing tolerant attitudes toward gays and lesbians.     

A multi-site comparison of supported housing for chronically homeless adults: "Housing first" versus "residential treatment first"

Both direct placement in supported community housing and pre-treatment with time-limited residential treatment are used as approaches to helping chronically homeless adults exit from homelessness but relative effectiveness and cost remains untested. The current observational study utilized data from a national, multi-site housing project to determine whether clients who receive residential treatment or transitional housing before being placed into independent housing achieve superior outcomes than clients who are immediately placed into independent housing, and whether they incur greater healthcare costs. A total of 709 participants (131 and 578 participants in the respective groups) were assessed every 3 months for 2 years on housing outcomes, community adjustment, work and income, mental and physical health, and health service costs. Clients who received immediate, independent housing had more days in their own place, less days incarcerated, and reported having more choice over treatment; but no differences on other clinical or community adjustment outcomes. In this observational study, there were no clinical advantages for clients who had residential treatment or transitional housing prior to entry into community housing, but they incurred higher substance abuse service costs. Studies using randomized controlled trials of these conditions are needed to establish causation.     

DIVINE ACTION IN THE WORLD (SYNOPSIS)

The following is a synopsis of the paper presented by Alvin Plantinga at the Ratio conference on The Meaning of Theism held in April 2005 at the University of Reading. The synopsis has been prepared by the Editor, with the author's approval, from a handout provided by the author at the conference. The paper reflects on whether religious belief of a traditional Christian kind can be maintained consistently with accepting our modern scientific worldview. Many theologians, and also many scientists, maintain that the idea of divine intervention is at odds with the framework of natural laws disclosed by science. The paper argues that this notion of a ‘religion/science problem’ is misguided. When properly understood, neither the classical (Newtonian) picture of natural laws, nor the more recent quantum mechanical picture, rules out divine intervention. There is nothing in science, under either the old or the new picture, that conflicts with, or even calls in to question, special divine action, including miracles.     

A Geographic Analysis of Chronically Homeless Adults Before and After Enrollment in a Multi-Site Supported Housing Initiative: Community Characteristics and Migration

The current study examined the community characteristics and migration of chronically homeless adults before and after entry into a multi-site supported housing initiative. A total of 394 participants were geocoded at baseline and 12-month follow up. Data from geographic information systems indicate that the median distance participants traveled from their last residence to their residence 1 year after program entry was 4.6 miles and 12% of participants traveled more than 100 miles. Participants moved into communities with higher population densities, larger proportions of Whites, and smaller proportions of Blacks following their entry into supported housing, but continued to live in communities with higher crime rates, lower education levels, and lower income levels then the state average. At 12 months, Black participants residing in communities with higher population densities and larger Black populations reported higher social support and lower subjective distress. This underscores the importance of considering client preferences in housing. Together, these findings suggest that supported housing programs may be successful in finding housing for homeless clients, but are not placing them in improved communities. Special attention may also be needed for some clients who travel long distances between residences.     

Vocational aspirations of Chinese high school students and their parents' expectations

This study examined the vocational aspirations and parental vocational expectations of high school students and their parents (1067 parent–child dyads). Participants completed a demographic questionnaire and an Occupations List. The Occupations List consisted of 126 occupational titles evenly distributed across the six Holland types. Parents were asked to check the occupations that they expected their children to pursue and students were asked to select occupations to which they aspired. The expectations of parents were compared to the aspirations of children according to the occupational field, prestige, and sextype of occupations. The expectation–aspiration gap was relatively small for occupational field, but the gap was larger for occupational prestige and sextype. There were also gender differences for both expectations (parents' expectation toward sons and daughters) and aspirations (aspirations of male and female students). Types of high school (key or regular high schools) and parental educational background also related to expectations and aspirations. Theoretical, research, and practice implications are discussed.     

The Primary Care Prescribing Psychologist Model: Medical Provider Ratings of the Safety, Impact and Utility of Prescribing Psychology in a Primary Care Setting

Family medicine providers at a large family medicine clinic were surveyed regarding their impression of the impact, utility and safety of the Primary Care Prescribing Psychologist (PCPP) model in which a prescribing psychologist is embedded in a primary care clinic. This article describes the model and provides indications of its strengths and weaknesses as reported by medical providers who have utilized the model for the past 2 years. A brief history of prescribing psychology and the challenges surrounding granting psychologists the authority to prescribe psychotropic medication is summarized. Results indicate family medicine providers agree that having a prescribing psychologist embedded in the family medicine clinic is helpful to their practice, safe for patients, convenient for providers and for patients, and improves patient care. Potential benefits of integrating prescribing psychology into primary care are considered and directions for future research are discussed.
