A criterion for unanimity in French’s theory of social power
French's use of digraph theory in social psychology (see –W31:–n 4473) is extended by providing a necessary and sufficient condition for the attainment of ultimate unanimity of opinions in a power structure. The isomorphism is demonstrated between French's formalization and the theory of higher transition probabilities in Markov chains. The concepts of "automorphic groups" and "power subgroups" are defined and developed

A formal theory of social power
This theory illustrates a way by which many complex phenomena about groups can be deduced from a few simple postulates about interpersonal relations. By the application of digraph theory we are able to treat in detail the patterns of relations whose importance has long been noted by the field theorists." Three major postulates are presented as well as a variety of theorems dealing with the effects of the power structure of the group, the effects of communication patterns, the effects of patterns of opinion, and leadership.

Literary Coteries and the Making of Modern Print Culture by Betty A. Schellenberg
"Literary Coteries and the Making of Modern Print Culture offers the first study of manuscript-producing coteries as an integral element of eighteenth-century Britain's literary culture. As a corrective to literary histories assuming that the dominance of print meant the demise of a vital scribal culture, the book profiles four interrelated and influential coteries, focusing on each group's deployment of traditional scribal practices, on key individuals who served as bridges between networks, and on the aesthetic and cultural work performed by the group. The book also explores points of intersection between coteries and the print trade, whether in the form of individuals who straddled the two cultures; publishing events in which the two media regimes collaborated or came into conflict; literary conventions adapted from manuscript practice to serve the ends of print; or simply poetry hand-copied from magazines. Together, these instances demonstrate how scribal modes shaped modern literary production. This title is also available as Open Access."

Verschwörungstheoretiker: Geschäftsmodell - Leben zerstören - SPIEGEL ONLINE
Gutjahr hat über die Tortur, die er und seine Familie durchleben, mittlerweile zwei online verfügbare Vorträge gehalten. Er geht in die Offensive, beschäftigt einen Anwalt, der gegen die Wortführer unter den Diffamierern vorgeht, auch im Ausland, offenbar mit Erfolg. Er rät allen Betroffenen in ähnlichen Fällen, sich zu wehren, und zwar möglichst frühzeitig.

Nach dem Bannstrahl gegen "Infowars"-Macher Alex Jones stellt sich aber vor allem für die Betreiber der großen Social-Media-Plattformen die Frage, wie sie in Zukunft mit all den anderen kleinen und großen Verschwörungstheoretikern umgehen sollen. Mit denen, die, um Geschäfte zu machen, stets einen wütenden Mob bei der Stange halten müssen, indem sie immer neue Ziele für dessen Aggression liefern.

Social Influence Bias: A Randomized Experiment | Science
Our society is increasingly relying on the digitized, aggregated opinions of others to make decisions. We therefore designed and analyzed a large-scale randomized experiment on a social news aggregation Web site to investigate whether knowledge of such aggregates distorts decision-making. Prior ratings created significant bias in individual rating behavior, and positive and negative social influences created asymmetric herding effects. Whereas negative social influence inspired users to correct manipulated ratings, positive social influence increased the likelihood of positive ratings by 32% and created accumulating positive herding that increased final ratings by 25% on average. This positive herding was topic-dependent and affected by whether individuals were viewing the opinions of friends or enemies. A mixture of changing opinion and greater turnout under both manipulations together with a natural tendency to up-vote on the site combined to create the herding effects. Such findings will help interpret collective judgment accurately and avoid social influence bias in collective intelligence in the future.

Norms in the Wild - Paperback - Cristina Bicchieri - Oxford University Press
The philosopher Cristina Bicchieri here develops her theory of social norms, most recently explained in her 2006 volume The Grammar of Society. Bicchieri challenges many of the fundamental assumptions of the social sciences. She argues that when it comes to human behavior, social scientists place too much stress on rational deliberation. In fact, many choices occur without much deliberation at all. Bicchieri's theory accounts for these automatic components of behavior, where individuals react automatically to cues--those cues often pointing to the social norms that govern our choices in a social world

Bicchieri's work has broad implications not only for understanding human behavior, but for changing it for better outcomes. People have a strong conditional preference for following social norms, but that also means manipulating those norms (and the underlying social expectations) can produce beneficial behavioral changes. Bicchieri's recent work with UNICEF has explored the applicability of her views to issues of human rights and well-being. Is it possible to change social expectations around forced marriage, genital mutilations, and public health practices like vaccinations and sanitation? If so, how? What tools might we use? This short book explores how social norms work, and how changing them--changing preferences, beliefs, and especially social expectations--can potentially improve lives all around the world.

--To-do: compare with Ullmann-Margalit's work. Don't remember the exact connections...
