The theme of "following the crowd can have disastrous consequences" as described in "The Lottery" by Shirley Jackson can be seen in various examples in our own world culture. One example could be in the case of mob mentality, where a group of people can become swept up in a particular way of thinking or acting and become willing to do things that they might not otherwise do if acting alone. This can lead to harmful or violent behavior, as seen in cases of lynchings, riots, and other forms of mob justice.
Another example could be seen in the case of conformist behavior, where people tend to conform to the beliefs and behaviors of those around them, even if they personally disagree with those beliefs or behaviors. This can lead to a lack of individuality and a failure to question authority or the status quo, which can be detrimental to the progress and well-being of society.
Additionally, it can be seen in the case of groupthink, where a group of people make poor decisions because they are too focused on maintaining unity and avoiding conflict, rather than considering all possible options and outcomes. This can be seen in the corporate and political decision-making, where groupthink can lead to bad policies, poor investments, and other negative consequences.
