Hi all, 

I put this calibration test together this morning. It pulls from a trivia API of over 150,000 questions so you should be able to take this many, many times before you start seeing repeats.

A few notes:

1. The questions are "Jeopardy" style questions so the wording may be strange, and some of them might be impossible to answer without further context. On these just assign 0% confidence.

2. As the questions are open-ended, there is no answer-checking mechanism. You have to be honest with yourself as to whether or not you got the right answer. Because what would be the point of cheating at a calibration test?

I can't think of anything else. Please let me know if there are any features you would want to see added, or if there are any bugs, issues, etc. 

**EDIT**

As per suggestion I have moved this to the main section. Here are the changes I'll be making soon:

• Label the axes and include an explanation of calibration curves.
• Make it so you can reverse your last selection in the event of a misclick.

Here are changes I'll make eventually:

• Create an account system so you can store your results online.
• Move trivia DB over to my own server to allow for flagging of bad/unanswerable questions.

Here are the changes that are done:

• Change 0% to 0.1% and 99% to 99.9%  
• Added second graph which shows the frequency of your confidence selections. 
• Color code the "right" and "wrong" buttons and make them farther apart to prevent misclicks.
• Store your results locally so that you can see your calibration over time.
• Check to see if a question is blank and skip if so.
