Final answer:
The irony in Shirley Jackson's 'The Lottery' lies in the contrast between the story's peaceful setting and its violent conclusion, challenging the reader's expectations about the nature of societal rituals.
Step-by-step explanation:
The story The Lottery by Shirley Jackson is ironic because it presents a stark contrast between the peaceful and idyllic setting described at the beginning and the horrific and brutal tradition of the lottery revealed at the end. The irony lies in the normalization of violence as a community event in what seems to be an otherwise average New England village. The congenial gathering of the villagers, a commonplace aspect of rural American life, culminates in an act of collective savagery, challenging the readers' notions of civility and underscoring the potential for inhumanity in social rituals.
