The male characters have prejudice. They believed that they can discover nothing important in areas of the house where Minnie spent most time. Because of their prejudice, they overlook important clues that are "trifles" to them, while women concern about the clues. Male characters search the barn and the bedroom, places where men have power, rather than the kitchen, the only place where a woman would be powerful. One important line, spoken by the sheriff, says of the kitchen "Nothing here but kitchen things." The main reason of their failure of finding the evidence is that they ignored the importance of woman's life and did not want to enter the "woman's sphere". The most important evidence, the dead canary that the two women find, was hidden in Minnie's sewing basket.
