As a remedy against fake news on social media, we examine the effectiveness of three different mechanisms for source ratings that can be applied to articles when they are initially published: expert rating (where reviewers fact-check articles, which aggregated provide rating), user article users rate and sources themselves). We conducted two experiments found influenced media users’ beliefs in behind mattered. Low ratings, would mark usual culprits spreading news, had stronger effects than...
Disinformation on social media—commonly called “fake news”—has become a major concern around the world, and many fact-checking initiatives have been launched in response. However, if presentation format of fact-checked results is not persuasive, may be effective. For instance, Facebook tested idea flagging dubious articles 2017 but concluded that it was ineffective removed feature. We conducted three experiments with media users to investigate two different approaches implementing fake news...
Abstract Objectives The objective was to understand how people respond coronavirus disease 2019 (COVID-19) screening chatbots. Materials and Methods We conducted an online experiment with 371 participants who viewed a COVID-19 session between hotline agent (chatbot or human) user mild severe symptoms. Results primary factor driving response hotlines (human chatbot) is perceptions of the agent’s ability. When ability same, users view chatbots no differently more positively than human agents....
Research shows that consuming ratings influences purchase decisions in e-commerce and also has modest effects on belief news articles social media. We find the act of producing reduces media induces users to think more critically. propose this intervention as a method encourage realize that, unlike product rating setting, who submit their for typically lack firsthand knowledge events reported news, making it difficult most rate accurately. asked 68 assess believability 42 measured cognitive...
We investigate whether the news presentation format affects believability of a story and engagement level social media users. Specifically, we test to see if highlighting source delivering can nudge users think more critically about truthfulness that they see, for obscure sources, ratings affect how evaluate truthfulness. also influence users' presented post (e.g., read, like, comment, share). find such changes in indeed have significant impacts on perceive act items.
Controlling digital piracy has remained a top priority for manufacturers of information goods, as well many governments around the world. Among forms taken by piracy, we focus on an increasingly common one—namely, online piracy—that is facilitated torrent sites and cyberlockers who bring together consumers pirated content its suppliers. Motivated recent empirical literature that makes clear distinction between antipiracy efforts restrict supply goods (supply-side enforcement) ones penalize...
Firms are beginning to use chatbots collect information from users (e.g., online reviews), a task traditionally done through forms. We used two experiments investigate how collecting reviews using in place of forms might impact user experience and, turn, alter the nature submitted by users. Study 1 compares web forms, finding that may improve perceived efficiency but otherwise have no discernible effect on satisfaction and usage intention. At same time, chatbot results shorter, lower-quality...
The video game industry has a robust secondhand market for games, even though some of the major gaming-console companies possess means to shut it down. What is special ingredient in this that would incentivize manufacturer give tacit approval buying and selling used games? In study, leveraging game-theoretic model, we investigate effect gaming console on manufacturer’s strategy presence games. We find when offers provides additional value outside playing games (e.g., media hub with apps),...
News—real or fake—is now abundant on social media. News posts media focus users' attention the headlines, but does it matter who wrote article? We investigate whether changing presentation format to highlight source of article affects its believability and how users choose engage with it. conducted two experiments found that nudging think about influenced extent which they believed The highlighting had a main effect; made more skeptical all articles, regardless source's credibility. For...
Since the time industry for e-books transitioned from wholesale to agency model, several interesting observations have been made. For instance, despite its revenue-sharing approach that is supposed be effective in addressing channel coordination issues present wholesaling, model has curiously led higher prices and less demand e-book market. The main purpose of current study provide insights into this curious market phenomenon by focusing on: (i) substitutability between printed- versions,...
Public health campaigns aimed at curbing the spread of COVID-19 are important in reducing disease transmission, but traditional information-based have received unexpectedly extreme backlash.This study to investigate whether customizing public service announcements (PSAs) providing guidelines match individuals' identities increases their compliance.We conducted a within- and between-subjects, randomized controlled cross-sectional, web-based July 2020. Participants viewed two PSAs: one...

We conduct two experiments to demonstrate that reliance algorithm following substantial error is affected by (i) when the occurs and (ii) how used in decision-making process. find impact an depends whether early (i.e., first start using algorithm) or late after have for extended period).

Errors are a natural part of the development and use predictive algorithms, but they could discourage people from relying on algorithms even when doing so lead to better decisions. In this paper, we conduct two experiments demonstrate that people's reliance algorithm following substantial error depends occurs how is used in decision making. We find that, prediction tasks fully delegated an algorithm, impact different if early versus late. While results persistent reduction, late affects only...

The rise of “fake news” has become a major concern for social media platforms. In response, Facebook proposed and tested the idea users flagging rating news articles sources, much akin to how consumers rate products services on Internet. One obvious challenge with this crowdsourced approach is whether really know enough sources. Perhaps, side benefit asking evaluate an article—and about their personal experience event described in article—is making them realize that they do not make accurate...
Online platforms are increasingly using tiered commission schemes to share revenues with sellers. However, the direction of scheme varies across platforms. While some platforms, such as Apple, charge higher commissions from high-revenue sellers, others rates low-revenue We develop a game-theoretic model an online marketplace show when it is optimal for favor or In particular, entry cost medium, platform prefers small players. Moreover, compared fixed schemes, while beneficial can reduce...
Misinformation on social media—commonly called “fake news”—has become a major concern around the world, and many fact-checking initiatives have been launched to mitigate problem. The way results are presented media users is important because if presentation format not persuasive, fact checking may little effect. Facebook implemented in 2017 but concluded that flagging dubious articles had no effect users’ beliefs subsequently removed feature. We conducted an experiment with 397 investigate...
