Ideological biases in social sharing of online information about climate change

of URLs were co-shared. Fig 3 shows the URL co-share network of the five largest communi- ties by total share count. The layout is determined by the ForceAtlas2 algorithm [50], which groups densely connected nodes together; visual inspection shows a clear partition into two large clusters. Algorithmic community detection reveals further partitioning within the larger cluster of the network, illustrated by the different node colours. By considering the contrasting structures found by the community detection and network layout algorithms, there is evidence of multiple layers of structure within the network. Note that the large yellow node separated Fig 2. Average domain ideological positions assigned by each coder and the overall average across all coders. Values should be thought of as standard deviations from the mean. Vertical bars indicate ± one standard deviation across the coders. https://doi.org/10.1371/journal.pone.0250656.g002 PLOS ONE Ideological biases in social sharing of online information about climate change PLOS ONE | https://doi.org/10.1371/journal.pone.0250656 April 23, 2021 11 / 25
