In some group situations, each individual may be less likely or slower to help because responsibility and interpretation are shared across the people present.

Would I Be Helped? Cross-National CCTV Footage Shows That Intervention Is the Norm in Public Conflicts

Research-assisted source review

What it supports
At least one bystander intervened in roughly nine out of ten conflicts, usually with several interveners. More bystanders were associated with a greater aggregate chance that someone helped.
Where it may not transfer
Observation cannot randomly assign crowd size or isolate diffusion of responsibility, and CCTV coding captures visible public conflict rather than private, online or non-violent situations. Aggregate intervention is different from each individual's likelihood of acting.
