To find where a rumor started, look for the least connected network.

Standard network theory says more connectivity is better for tracing information, but once a system hits 'information overload,' that logic flips. In dense networks, the sheer volume of data creates noise that masks the original signal's path. This study found that less connected networks actually make it easier to pinpoint a signal's source because there are fewer competing paths to muddy the waters. It’s a complete reversal of how we think about efficiency and transparency in communication. This suggests that in our hyper-connected world, more links might actually be helping the originators of misinformation stay hidden in the crowd.
