Neighborliness: Do posters cluster together or spread out?
We measured the distance between each newly placed object and its closest neighbor at the time of posting. We call this a neighborly proximity - or 'neighborliness'.
Posts that are 1-2 units away from an existing post are said to be neighborly.
We can think of general 'neighborliness' as a measurement of preference for either clustering, or spreading out as we co-occupy space.
For the first 200 placed objects, 82% were exactly 2 units away from an existing post.
This shows that the bulk of posters exhibit a neighborly tendancy, but avoid directly touching others, if possible.
However, as the space starts to fill, the choice to spread out disappers, which is why in both figures we see a quick decay of spread-out posting.
Open space is quickly exhausted.
From left to right we are seeing the neighborly proximities, in groups of 50. It should read like a timeline.
What's interesting here is that even in the beginning, when players had the most freedom to spread out, we still see a bias towards 2-unit distances.
Clustering seems like a general preference in co-occupied space.
If we were interested in further investigating this behavior, we might create a simulated posting environment that presents each tester with an identical option to post near or far. Would most people post in the same way with the same context?
Below is a table showing counts in sets of 100 posts.
