Safety in numbers is the hypothesis that, by being part of a large physical group or mass, an individual is proportionally less likely to be the victim of a mishap, accident, attack, or other bad event. Some related theories also argue (and can show statistically) that mass behaviour (by becoming more predictable and "known" to other people) can reduce accident risks, such as in traffic safety - in this case, the safety effect creates an actual reduction of danger, rather than just a redistribution over a larger group. So science again confirms scripture.
Hebrews 10:25 And let us not neglect our meeting together, as some people do, but encourage one another, especially now that the day of his return is drawing near. (NLT)
