According to this I have 17/5 for the Curious badge. So I have effectively 'earned' this badge more than 3 times over. So why haven't I received it yet? I have maintained a positive question record so what do I have to do to get this elusive badge?
If you click on the bronze bar, it shows that having a positive question record is the requirement you need to fulfull.
A full description of the requirements for the badge is available on Meta Stack Exchange. It includes the requirement for a positive question record:
- A positive question record means you don't have too many closed, downvoted or deleted questions, overall. The formula is
(total questions - negative questions - closed - deleted)/total questions ≥ 0.5. Questions that have been downvoted and closed and deleted count three times in this calculation!
Looking over your profile, I see that you have enough negative-score, closed, and/or deleted questions to make this statistic less than 0.5.
