There are many examples of mob mentality in LOTF. One example in the novel is in chapter nine, when Simon kicks the bucket with the help of his so called friends. IN chapter nine Ralph and company is invited to a feast hosted by Jack and his new tribe. When things get a little wild people stop thinking as individuals but as a mob, and that's exactly what happens at the feast. Poor Simon has just come from the jungle only to be mistaken for the beast. The group, not thinking straight brutally attacks Simon, killing him.
