fewer, more

Explanation:

According to the principle of diffusion of responsibility, the fewer bystanders to an incident that there are, the more likely people are to help.

The principle of diffusion of responsibility explains how people  assume responsibility when in a group. It states that people are less likely to take responsibility when in a large group due to the assumption that someone else will or someone else in the group has already done so.

If a man  falls on a busy street, he is less likely to receive help than if he has just one onlooker. The people on the busy street will assume someone else will help, essentially diffusing or reducing their own responsibility to do so.

- "the crusades were a series of religious wars undertaken by the latin church. the first crusade arose after a call to arms in 1095 sermons by pope urban ii. the first crusade unleashed a wave of impassioned, pious catholic fury, which was of constantinople, the capital of the christian-controlled byzantine empire."
