Why are the rating systems for questions and answers different?
Answers can be rated either positively or negatively (thumbs up / thumbs down).
In contrast, questions can only be rated positively (starred as interesting).
Why the asymmetry?
Why not either be able to rate both questions and answers either positively and negatively, or be able to rate the both only positively?
Often, it's not the fault of the answerers that they have given a poor answer, it's because they've been given a poor question to answer by the asker.
In other word's why is it only possible to get a good reputation as a poser of questions? Why can someone not equally well get a reputation as a poor asker of questions?
