Why do the men fail to see the clues that Mrs. Hale and Mrs. Peters discover?

The clues and evidence noted by the women are seen as 'trifles,' women's details, like women's work is just worrying about the little things, and they don't mean much of anything. The men tease the women about their discoveries and in a way laugh at them. They're just silly, uneducated housewives you know.
