Becca-Calibration

How well do your friends know you?

Create a quiz of true and false statements about yourself. Share it with friends, lovers, or someone you have a weird liminal uncertain relationship with — and discover how well-calibrated their guesses are.

Calibration measures whether confidence matches accuracy. A well-calibrated person who says “I'm 80% sure” is right about 80% of the time.

How it works

  1. 1.Write true and false statements about yourself
  2. 2.Share the link with friends
  3. 3.They guess True/False and rate their confidence (50-99%)
  4. 4.See how well their confidence matched reality

Strongly recommended: Workshop your false statements with an AI before submitting. The quiz is only as good as your falses — and a few minutes with ChatGPT or Claude will turn obvious fakes into genuinely tricky ones.
