To test or not to test: A clinical dilemma

This paper argues that clinicians are sometimes justified in not testing diagnoses or in not subjecting them to a full battery of tests. In deciding whether to conduct a test, a clinician may consider and weigh several different factors, including her confidence in her initial diagnosis, the specificity and sensitivity of the test, the consequences of making a false diagnosis, the pain, harm, and inconvenience caused by the test, and the costs of the test to the patient and society. This view suggests that diagnoses are fundamentally different from scientific hypotheses in that they are not always subjected to the same evidential standards.     

A solution to the discursive dilemma

An impossibility result pertaining to the aggregation of individual judgements is thought by many to have significant implications for political theory, social epistemology and metaphysics. When members of a group hold a rational set of judgments on some interconnected questions, the theorem shows, it isn’t always (logically) possible for them to aggregate their judgements into a collective one in conformity with seemingly very plausible constraints. I reject one of the constraints which engender the dilemma. The analogy with the lottery paradox, I argue, shows that rational belief needn’t be consistent. So the alleged implications of the dilemma are dispelled.     

The give-or-take-some dilemma: An empirical investigation of a hybrid social dilemma

We describe and empirically investigate a hybrid social dilemma that merges give-some and take-some dilemmas by allowing individuals to choose to either give or to take resources from a shared resource pool. Study 1 finds that (a) group size increases the inequality among group members and the likelihood of creating the public good, while reducing the amount of wasted resources; (b) larger bonuses increase provision rates; and (c) asymmetry in the wealth distribution of the group members induces higher levels of inequality of the final outcomes. Following the logic of appropriateness, players with high (low) endowments were more likely to give toward (take from) the shared resource. Study 2 finds that the tendency of the players with high (low) endowments to give (take) is amplified as the difference between endowment levels increased, and the players’ behavior is correlated with, and predictable from, independent judgments of what is perceived as appropriate.     

Still the same dilemma for conceptual engineers: reply to Koch

Philosophical Studies - Steffen Koch (Koch 2020) raises several objections to my critique of conceptual engineering (Deutsch in ‘Speaker’s Reference, Stipulation, and a Dilemma for...     

Our existential dilemma:Bor orBe'er

An evaluation is made of the choices available to individuals in dealing with their essential alone-ness, the existential dilemma; and a parallel is drawn between these choices and flowing and stagnant waters, as interpreted by traditional sources.     

Similarity and acquaintance: a dilemma

There is an interesting and instructive problem with Richard Fumerton’s acquaintance theory of noninferential justification. Fumerton’s explicit account requires acquaintance with the truth-maker of one’s belief and yet he admits that one can have noninferential justification when one is not acquainted with the truth-maker of one’s belief but instead acquainted with a very similar truth-maker. On the face of it this problem calls for clarification. However, there are skeptical issues lurking in the background. This paper explores these issues by developing a dilemma for an acquaintance theory.     

FISH: a commons dilemma simulation

A local-area-network-based commons dilemma (CD) simulation is described. The program usesfishing as its CD metaphor; research participants experience the metaphor through both graphics (fish may be seen in an ocean) and text (CD terms such as “resource regeneration” are translated to fishing terms such as “spawning”). Common CD parameters, such as the availability of the resource, payoff values, the number of harvesters, the rate of regeneration, knowledge about the state of the resource, and awareness of other harvesters’ actions may be varied Other CD parameters that are not yet widely studied may also be varied, such as variability in regeneration rate, uncertainty in the amount of the resource, operating costs necessary to harvest the resource, length of time for the resource to regenerate (spawn), and whether the resource is visible to harvesters. The program worked well in pilot testing and in a study in progress.     

The police officer's dilemma: using ethnicity to disambiguate potentially threatening individuals

Using a simple videogame, the effect of ethnicity on shoot/don't shoot decisions was examined. African American or White targets, holding guns or other objects, appeared in complex backgrounds. Participants were told to "shoot" armed targets and to "not shoot" unarmed targets. In Study 1, White participants made the correct decision to shoot an armed target more quickly if the target was African American than if he was White, but decided to "not shoot" an unarmed target more quickly if he was White. Study 2 used a shorter time window, forcing this effect into error rates. Study 3 replicated Study 1's effects and showed that the magnitude of bias varied with perceptions of the cultural stereotype and with levels of contact, but not with personal racial prejudice. Study 4 revealed equivalent levels of bias among both African American and White participants in a community sample. Implications and potential underlying mechanisms are discussed.
