“People Who Argue Ad Hominem Are Jerks” and Other Self-Fulfilling Fallacies

A self-fulfilling fallacy (SFF) is a fallacious argument whose conclusion is that the very fallacy employed is an invalid or otherwise illegitimate inferential procedure. This paper discusses three different ways in which SFF’s might serve to justify their conclusions. SFF’s might have probative value as honest and straightforward arguments, they might serve to justify the premise of a meta-argument or, following a point made by Roy Sorensen, they might provide a non-inferential basis for accepting their conclusion. The paper concludes with an assessment of the relative merits of these proposals.     

Is the Generality Problem too General?

Reliabilism holds that knowledge is true belief reliably caused. Reliabilists should say something about individuating processes; critics deny that the right degree of generality can be specified without arbitrariness. It is argued that this criticism applies as well to processes mentioned in scientific explanations. The gratuitous puzzles created thereby show that the "generality problem" is illusory.     

Forgiveness: Who Does It and How Do They Do It?

Forgiveness is a suite of prosocial motivational changes that occurs after a person has incurred a transgression. People who are inclined to forgive their transgressors tend to be more agreeable, more emotionally stable, and, some research suggests, more spiritually or religiously inclined than people who do not tend to forgive their transgressors. Several psychological processes appear to foster or inhibit forgiveness. These processes include empathy for the transgressor, generous attributions and appraisals regarding the transgression and transgressor, and rumination about the transgression. Interpreting these findings in light of modern trait theory would help to create a more unified understanding of how personality might influence forgiveness.     

Interpersonal communication and personality: Self and other perspectives

This study was designed to examine the links between the personality of group members and their styles of communication in task groups meeting over a three-month period. Comprehensive measures of personality and of communication styles were taken from the perspectives both of the actor (the self) at the beginning of the group's life and his or her fellow group members (the others) at the end of the group's life. Even after extensive group interaction, these two sets of ratings converged only when observable characteristics were being measured (e.g., extraversion in personality or precision in communication). Self-rated personality across eight dimensions predicted two of the three self-rated dimensions of communication style (Verbal Engagement and Attentiveness to the Other) at only moderate levels; the actor's personality rated on the same eight dimensions by others predicted the actor's communication style as rated by these same others on all three dimensions (Verbal Engagement, Attentiveness to the Other, and Feelings versus Silence), and at much stronger levels than did self-ratings of personality. Both personality and communication styles as rated by others were able to predict the key social outcomes of the actor's likability and task contribution, whereas self-ratings were not. Ratings derived from the self and those derived from others about the self thus appear to develop from different sources of information and relate to different outcomes. The links between personality and communication style are largely confined to the perspective (self versus other) from which they were measured.     

A variable-selection heuristic for K-means clustering

One of the most vexing problems in cluster analysis is the selection and/or weighting of variables in order to include those that truly define cluster structure, while eliminating those that might mask such structure. This paper presents a variable-selection heuristic for nonhierarchical (K-means) cluster analysis based on the adjusted Rand index for measuring cluster recovery. The heuristic was subjected to Monte Carlo testing across more than 2200 datasets with known cluster structure. The results indicate the heuristic is extremely effective at eliminating masking variables. A cluster analysis of real-world financial services data revealed that using the variable-selection heuristic prior to the K-means algorithm resulted in greater cluster stability.     

Too Many Blacks,Too Many Whites: Is There Racial Balance?

Racial conflict between African Americans and Whites has been observed to occur most frequently at two critical points: when African Americans make up approximately 30% of a given group or when African Americans make up approximately 50% of a given group. These two critical ratios are referred to as the J and (inverted) U patterns of racial conflict, respectively. To date, most of the data supporting either the J or U models have been derived from large demographic studies that do not directly assess individual perceptions. Thus, little is known about the individual reactions of members from either racial group to varying percentages of group racial composition. This small-group experiment examined the responses of African-American and White subjects to their inclusion in four-person groups of varying racial compositions. Three racial configurations were created and included the following percentages of African Americans: 25%, 50%, and 75%. The results support the U model of racial conflict. Moreover, the U model fit the data equally well for African Americans and Whites.     

Chaotic attractors in the therapeutic system 1

Because little research had been done on the presence and role of latent communication in the context of team‐conducted family therapy, the writers set out to monitor unconscious responses generated under these conditions. Specifically, they investigated an ongoing family treatment situation conducted according to the “reflecting team model.” One team of therapists handles the actual treatment session, while the other observes from behind a one‐way mirror. During the course of a session, the second team makes suggestions to the treatment team either by telephone or by calling the therapists out of the treatment room.

As the project developed, the writers found that the unconscious responses of both family and treatment teams indicated a process at work beyond the conscious intentions of the participants. That is, the therapeutic enterprise was functioning as a dynamical system, whose increasing complexity suggested a self organizing principle at work. This paper traces the development of the system's movement toward greater complexity, identifies the specific interventions that indicate this process, describes how all participants demonstrated a high degree of resonance and synchronization with this overarching‐self organizing pattern. This paper serves to alert therapists to the role of unconscious communication within the therapeutic system and postulates that the generation of form within psychotherapy follows many of the same self organizing processes found in other human and non human systems.
