Why do people have such a difficult time ignoring questions they don't like?

I’m just wondering because I don’t have this mindset, so I don’t exactly understand how it works.

Is it just seeing the question there that enrages you? So many people have spoken of “having to read” certain questions. When do you ever have to read a question here? I don’t really understand that. Do you click on questions you don’t like on purpose or is it just seeing them in the list of questions that bothers you?
