量化社会影响的效果

Quantifying the effects of social influence

Pavlin Mavrodiev, Claudio J. Tessone, Frank Schweitzer

摘要:

人类在做决策时如何应对间接的社会影响?我们分析了一个实验,在这个实验中,受试者必须反复猜测事实问题的正确答案,而只有关于其他人答案的汇总信息。虽然人类对汇总信息的反应是一种广泛观察到的现象,但尚未在受控环境中对其进行定量研究。我们发现,个人猜测的调整线性依赖于所有猜测的平均值的距离。这是一个显著的,但令人惊讶的简单的统计规律。它适用于所有分析的问题,即使正确的答案在几个数量级上不同。我们的研究结果支持的假设,个体多样性并不影响间接的社会影响的反应。它还补充了以前的结果在信息丰富的情况下的非线性响应。我们认为,对社会影响的反应的性质与信息聚合的水平发生了至关重要的变化。这种见解有助于社会影响下的集体决策模型的经验基础。

英文摘要:

How do humans respond to indirect social influence when making decisions? We analysed an experiment where subjects had to repeatedly guess the correct answer to factual questions, while having only aggregated information about the answers of others. While the response of humans to aggregated information is a widely observed phenomenon, it has not been investigated quantitatively, in a controlled setting. We found that the adjustment of individual guesses depends linearly on the distance to the mean of all guesses. This is a remarkable, and yet surprisingly simple, statistical regularity. It holds across all questions analysed, even though the correct answers differ in several orders of magnitude. Our finding supports the assumption that individual diversity does not affect the response to indirect social influence. It also complements previous results on the nonlinear response in information-rich scenarios. We argue that the nature of the response to social influence crucially changes with the level of information aggregation. This insight contributes to the empirical foundation of models for collective decisions under social influence.
