Social Influence Bias
The social influence bias is an asymmetric herding effect on online social media platforms which makes users overcompensate for negative ratings but amplify positive ones. Positive social influence can accumulate and result in a rating bubble, while negative social influence is neutralized by crowd correction. This phenomenon was first described in a paper written by Lev Muchnik, Sinan Aral and Sean J. Taylor in 2014, then the question was revisited by Cicognani et al., whose experiment reinforced Munchnik's and his co-authors' results. Relevance Online customer reviews are trusted sources of information in various contexts such as online marketplaces, dining, accommodation, movies, or digital products. However, these online ratings are not immune to herd behavior, which means that subsequent reviews are not independent from each other. As on many such sites, preceding opinions are visible to a new reviewer, he or she can be heavily influenced by the antecedent evaluations in ...

Influence-for-hire
Influence-for-hire or collective influence, refers to the economy that has emerged around buying and selling Social influence, influence on social media platforms. Overview Companies that engage in the influence-for-hire industry range from content farms to high end public relations agencies. Traditionally influence operations have largely been confined to public sector actors like intelligence agencies, in the influence-for-hire industry the groups conduction the operations are private with commerce being their primary consideration. However many of the clients in the influence-for-hire industry are countries or countries acting through proxies. They are often located in countries with less expensive digital labor.

Cognitive Biases
A cognitive bias is a systematic pattern of deviation from norm or rationality in judgment. Individuals create their own "subjective reality" from their perception of the input. An individual's construction of reality, not the objective input, may dictate their behavior in the world. Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation, or what is broadly called irrationality. Although it may seem like such misperceptions would be aberrations, biases can help humans find commonalities and shortcuts to assist in the navigation of common situations in life. Some cognitive biases are presumably adaptive. Cognitive biases may lead to more effective actions in a given context. Furthermore, allowing cognitive biases enables faster decisions which can be desirable when timeliness is more valuable than accuracy, as illustrated in heuristics. Other cognitive biases are a "by-product" of human processing limitations, resulting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crowd Psychology
Crowd psychology, also known as mob psychology, is a branch of social psychology. Social psychologists have developed several theories for explaining the ways in which the psychology of a crowd differs from and interacts with that of the individuals within it. Major theorists in crowd psychology include Gustave Le Bon, Gabriel Tarde and Sigmund Freud. This field relates to the behaviors and thought processes of both the individual crowd members and the crowd as an entity. Crowd behavior is heavily influenced by the loss of responsibility of the individual and the impression of universality of behavior, both of which increase with crowd size. Origins The first debate in crowd psychology began in Rome at the first International Congress of Criminal Anthropology on 16 November 1885. The meeting was dominated by Cesare Lombroso and his fellow Italians, who emphasized the biological determinates. : "Lombroso detailed before the first congress his theories of the physical anomalies ...

Twitter Bomb
The term twitter bomb or tweet bomb (also spelled as one word) refers to posting numerous (pejoratively, "spamming") Tweets with the same hashtags and other similar content, including @messages, from multiple accounts, with the goal of advertising a certain meme, usually by filling people's Tweet feeds with the same message, and making it a "trending topic" on Twitter.Ethan Zuckerman"The Tweetbomb and the Ethics of Attention" April 20, 2012, Last accessed on April 30, 2012.J.

Twitter Bot
A Twitter bot is a type of software bot that controls a Twitter account via the Twitter API. The social bot software may autonomously perform actions such as tweeting, re-tweeting, liking, following, unfollowing, or direct messaging other accounts. The automation of Twitter accounts is governed by a set of automation rules that outline proper and improper uses of automation. Proper usage includes broadcasting helpful information, automatically generating interesting or creative content, and automatically replying to users via direct message. Improper usage includes circumventing API rate limits, violating user privacy, spamming, and sockpuppeting. Twitter bots may be part of a larger botnet. They can be used to influence elections and in misinformation campaigns. Twitter's policies do allow non-abusive bots, such as those created as a benign hobby or for artistic purposes, or posting helpful information. Types Positive influence Many non-malicious bots are popular for their en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sockpuppet (Internet)
A sock puppet is defined as a person whose actions are controlled by another. It is a reference to the manipulation of a simple hand puppet made from a sock, and is often used to refer to alternative online identities or user accounts used for purposes of deception. Online, it came to be used to refer to a false identity assumed by a member of an internet community who spoke to, or about, themselves while pretending to be another person. The use of the term has expanded to now include other misleading uses of online identities, such as those created to praise, defend, or support a person or organization, to manipulate public opinion, or to circumvent restrictions, such as viewing a social media account that they are blocked from, suspension, or an outright ban from a website. A significant difference between a pseudonym and a sock puppet is that the latter poses as a third party independent of the main account operator. Sock puppets are unwelcome in many online communities a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Spam
Social spam is unwanted spam content appearing on social networking services, social bookmarking sites, and any website with user-generated content (comments, chat, etc.). It can be manifested in many ways, including bulk messages, profanity, insults, hate speech, malicious links, fraudulent reviews, fake friends, and personally identifiable information. History As email spam filters became more effective, catching over 95% of these messages, spammers have moved to a new target – the social web. Over 90% of social network users have experienced social spam in some form. Those doing the “spamming” can be automated spambots/social bots, fake accounts, or real people. Social spammers often capitalize on breaking news stories to plant malicious links or dominate the comment sections of websites with disruptive or offensive content. Social spam is on the rise, with analysts reporting over a tripling of social spam activity in six months. It is estimated that up to 40% of all soci ...

Media Bias
Media bias is the bias of journalists and news producers within the mass media in the selection of many events and stories that are reported and how they are covered. The term "media bias" implies a pervasive or widespread bias contravening of the standards of journalism, rather than the perspective of an individual journalist or article. The direction and degree of media bias in various countries is widely disputed. Practical limitations to media neutrality include the inability of journalists to report all available stories and facts, and the requirement that selected facts be linked into a coherent narrative. Government influence, including overt and covert censorship, biases the media in some countries, for example China, North Korea, Syria and Myanmar. Politics and media bias may interact with each other; the media has the ability to influence politicians, and politicians may have the power to influence the media. This can change the distribution of power in society. Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social-desirability Bias
In social science research, social-desirability bias is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others. It can take the form of over-reporting "good behavior" or under-reporting "bad", or undesirable behavior. The tendency poses a serious problem with conducting research with self-reports. This bias interferes with the interpretation of average tendencies as well as individual differences. Topics subject to social-desirability bias Topics where socially desirable responding (SDR) is of special concern are self-reports of abilities, personality, sexual behavior, and drug use. When confronted with the question "How often do you masturbate?," for example, respondents may be pressured by the societal taboo against masturbation, and either under-report the frequency or avoid answering the question. Therefore, the mean rates of masturbation derived from self-report surveys are likely to be sever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Bot
A social bot, or also described as a social AI or social algorithm, is a software agent that communicates autonomously on social media. The messages (e.g. tweets) it distributes can be simple and operate in groups and various configurations with partial human control (hybrid) via algorithm. Social bots can also use artificial intelligence to express messages in more natural human dialogue. Uses * To influence peoples decisions, e.g.: advertise a product, support a political campaign, increase engagement statistics for social media pages, etc. * To provide low cost customer service agent to answer questions that their users might have. * To automatically answer commonly asked questions on Social media such as Discord. Lutz Finger identifies five immediate uses for social bots: *foster fame: having an arbitrary number of (unrevealed) bots as (fake) followers can help simulate real success. *Influence-for-hire: refers to the economy that has emerged around buying and selling inf ...

Response Bias
Response bias is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions. These biases are prevalent in research involving participant self-report, such as structured interviews or surveys. Response biases can have a large impact on the validity of questionnaires or surveys. Response bias can be induced or caused by numerous factors, all relating to the idea that human subjects do not respond passively to stimuli, but rather actively integrate multiple sources of information to generate a response in a given situation. Because of this, almost any aspect of an experimental condition may potentially bias a respondent. Examples include the phrasing of questions in surveys, the demeanor of the researcher, the way the experiment is conducted, or the desires of the participant to be a good experimental subject and to provide socially desirable responses may affect the response in some way. All of these "artifacts" of survey and self ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
