How it works
Things I Believe is a notebook with a memory. You write down what you think is true, and it asks you about it again later.
A belief is one sentence
Each entry is a single claim, stated as plainly as you can manage, plus a conviction score from 0 to 100 and — optionally — your reasoning. Keeping it to one claim is what makes it possible to see movement later. “My politics” can't change measurably. “Rent control does more harm than good” can.
Revisiting doesn't overwrite
When you revisit a belief you write it again from scratch, with today's wording and today's number. The old version stays. Over time you get a timeline and a line chart of your own conviction — including the times you moved and then moved back.
You set the rhythm per belief: monthly for things in flux, yearly for the load-bearing ones, never for the ones you just want to record. Due beliefs collect in your Revisit list. Nothing is emailed to you and nothing nags.
Private by default
New beliefs are private unless you change the default in settings. Private means private: not on your profile, not in Explore, not visible to anyone with the link. You publish one belief at a time, and you can un-publish at any point.
Comparing notes
Public beliefs can be responded to: I agree, partly,
I disagree, or not sure, with an optional note. Visit
/compare/username and the two of you are sorted into four groups — common ground,
partial agreement, real differences, and the ones nobody has answered yet.
The percentage at the top is deliberately crude. It's there to be ignored in favour of the lists underneath, which tell you the thing worth knowing: which claim you actually part ways on. Most arguments never get that far.
Your data is yours
Export everything as JSON from your settings page, any time, including the full history of every belief. Deleting your account deletes all of it — beliefs, revisions, responses, sessions.
