确认偏差对社交网络中竞争信息传播的影响

Impact of Confirmation Bias on Competitive Information Spread in Social Networks

Yanbing Mao, Emrah Akyol, Naira Hovakimyan

摘要:

本文研究了确认偏差对竞争信息在网络社会网络中传播的影响,网络社会网络由社会网络中的个体和网络层的竞争信息源组成。我们制定的问题作为一个零和博弈,它承认一个唯一的纳什均衡在纯策略。我们刻画了纯纳什均衡对公众先天观点、社会网络拓扑以及确认偏差参数的依赖性。我们发现,只有当先天意见不中立时,确认偏差才会使均衡向中心移动,而这种移动不会同时发生在竞争性信息源上。在著名的Krackhartt的建议网络的背景下的数值例子来证明理论结果的正确性。

英文摘要:

This paper investigates the impact of confirmation bias on competitive information spread in the cyber-social network that comprises individuals in a social network and competitive information sources in cyber layer. We formulate the problem as a zero-sum game, which admits a unique Nash equilibrium in pure strategies. We characterize the dependence of pure Nash equilibrium on the public's innate opinions, the social network topology, as well as the parameters of confirmation bias. We uncover that confirmation bias moves the equilibrium towards the center only when the innate opinions are not neutral, and this move does not occur for the competitive information sources simultaneously. Numerical examples in the context of well-known Krackhardt's advice network are provided to demonstrate the correctness of theoretical results.
