What is the main theme in the story " A Jury of Her Peers"?

The main theme in the story is the gender roles of the men
and women. The men are there as the legal representatives to determine what happened,
but it is their wives who are able to determine much more about what happened because
they notice things their husbands are blind to. The men leave the kitchen, remarking
that there's "nothing here but kitchen things", but the women are able to determine Mrs.
Wright's frame of mind by how she left her kitchen. When the men see as "trifles", the
women see as significant clues. Since both of the women hae been farmers' wives
themselves, they understand the isolation Mrs. Wright must have felt and how the event
of her dead canary would upset her.

The attitude of the men show their
bias of how they view women. The attorney jokes about them keeping their eyes open in
case they come upon a clue, and the sheriff responds they wouldn't recognize it as a
clue anyway. The women are not respected by their husbands for their minds. Their place
is in the home doing the typical "wifely" duties.

In the end, only the
two women can understand how Mrs. Wright felt and how she was treated by her husband.
They see her worn clothes, the awful stove she had to cook on, and that her husband
would never buy her a telephone to relieve her loneliness. The men will never understand
this part of Mrs. Wright's life.
