Negative valence can evoke a liberal response bias in syllogistic reasoning

Recently, studies have demonstrated that negative valence reduces the magnitude of the belief-bias effect in syllogistic reasoning. This effect has been localized in the reasoning stage, in the form of increased deliberation on trials where validity and conclusion believability are incongruent. Here, using signal detection theory, we show that the attenuation of belief bias observed when valence was negative can also be evoked by a liberal response bias at the decision stage. Indeed, when valence was negative participants adopted a more liberal criterion for judging syllogisms as “valid,” and were overconfident in their judgments. They also displayed less sensitivity in distinguishing between valid and invalid syllogisms. Our findings dovetail with recent evidence from memory research suggesting that negative valence can evoke a liberal response bias without improving performance. Our novel contribution is the demonstration that the attenuating effect of negative valence on belief bias can take multiples routes—by influencing the decision stage as was the case here, the reasoning stage as has been demonstrated elsewhere, and potentially both stages.     

The hostile media phenomenon: biased perception and perceptions of media bias in coverage of the Beirut massacre

After viewing identical samples of major network television coverage of the Beirut massacre, both pro-Israeli and pro-Arab partisans rated these programs, and those responsible for them, as being biased against their side. This hostile media phenomenon appears to involve the operation of two separate mechanisms. First, partisans evaluated the fairness of the media's sample of facts and arguments differently: in light of their own divergent views about the objective merits of each side's case and their corresponding views about the nature of unbiased coverage. Second, partisans reported different perceptions and recollections about the program content itself; that is, each group reported more negative references to their side than positive ones, and each predicted that the coverage would sway nonpartisans in a hostile direction. Within both partisan groups, furthermore, greater knowledge of the crisis was associated with stronger perceptions of media bias. Charges of media bias, we concluded, may reflect more than self-serving attempts to secure preferential treatment. They may result from the operation of basic cognitive and perceptual mechanisms, mechanisms that should prove relevant to perceptions of fairness or objectivity in a wide range of mediation and negotiation contexts.     

A plea for minimally biased naturalistic philosophy

Synthese - Naturalistic philosophers rely on literature search and review in a number of ways and for different purposes. Yet this article shows how processes of literature search and review are...     

Discrimination and liberal neutrality

This paper examines the political philosophy of Liberalism with particular focus on the principles of liberal neutrality and value pluralism. These principles, which are advocated by the most prominent contemporary liberal theorists mark a significant departure from classical liberalism and its monistic approach to seeking truth and the good. I argue that the shift to neutrality and pluralism have done a disservice to liberalism and that the cultivation of discrimination skills is needed to deal with the complex tasks of making decisions intelligently and effectively.

The moral basis of liberal education

The moral right to liberal education involves issues of distribution and of content. The former issue bears on the distribution of educational resources. The latter issue bears on the issue of multiculturalism. Both issues are discussed from the standpoint of equal rights.Presented as the first Distinguished Lecture to the Association for Philosophy of Education at its meeting in New York, 28 December 1991.
