The influence of diversity and experience on the effects of crowd size

Lionel P. Robert, Daniel M. Romero
2016 Journal of the Association for Information Science and Technology  
To better understand the effects of crowd size we conducted a study on the retention and performance based on 4,317 articles in the WikiProject Film community.  ...  The literature is unclear, however, about the relationship between the size of crowds and its impact on outcomes.  ...  A preliminary version of part of this article (Robert & Romero, 2015) appears in the Proceedings of the SIGCHI Conference on Human Factors in Computing Systems, ACM, 2015.  ...

Demographically diverse crowds are typically not much wiser than homogeneous crowds

Stephanie de Oliveira, Richard E. Nisbett

This material is based upon work supported by the National Science Foundation Graduate Research Fellowship Program under Grant DGE 1256260, awarded to S.d.O.  ...  The Model: Diverse Crowd Accuracy as a Function of Effect Size and Bracketing We modeled the wisdom of homogeneous and diverse crowds from two simulated, hypothetical social groups to demonstrate the above  ...  As these parameters varied, the relative accuracy of diverse (vs. homogeneous) crowds varied. The manipulations, which we refer to as "effect size" and "bracketing," are described below. Effect Size.  ...

2014 2014 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM 2014)  
To that end, in this paper, we propose to consider the magnitude of influence and the diversity of the influenced crowd simultaneously.  ...  Finally, we run extensive experiments on two real-world datasets, showing that our formulation is effective in generating diverse results.  ...  Effect of Diversification To show the effect of diversification of social influence on different seedset sizes, we fix the value of γ to 1 ( which corresponds to the maximum possible diversity that could  ...

Prediction diversity and selective attention in the wisdom of crowds [article]

Davi A. Nobre, José F. Fontanari
2020 arXiv   pre-print
The poor accuracy of the crowd on some experiments lead us to conjecture that its alleged accuracy is most likely an artifice of selective attention.  ...  Here we report the results of three experiments to probe the current understanding of the wisdom of crowds, namely, the estimates of the number of candies in a jar, the length of a paper strip, and the  ...  In Section III we describe and analyze the results of our three experiments, emphasizing the influence of the prediction diversity on the accuracy of the collective estimate.  ...
