A survey shows there is a shortage of women who are software developers. Sarah replies to it saying the reason is because women feel intimidated by the men to women ratio in the workplace.
John replies saying a reason for the shortage could be that women generally prefer roles where they interact with other people as well as they prefer a work-life balance.
Sarah tells John he is statement is incorrect, he doesn't know what he is talking about and she is correct.
Both Sarah and John are correct How would you with a single/ two words describe her or her stance of only believing/focus on one answer, her answer, when there are multiple answers.
Another example:
Pete says an elephant has a trunk. Dave says an elephant has tusks. Pete says Dave is incorrect but he is correct. Both are correct. Which single/ two words would convey that Pete's view is correct but at the same time incorrect by discounting Dave's view.
