Show HN: I Built Paul Graham's Intellectual Captcha Idea

PG has posted about improving social networks using something like an “intellectual CAPTCHA” many times [1][2][3][4] - “Make users pass a test on basic concepts like the distinction between necessary and sufficient conditions before they can tweet.” I felt the same way.

So I built one using a mix of simple math, logic, and Twitter/X Community Noted posts.

Try sample questions here - https://mentwire.com/sample - without signing up. - Invites are temporarily open to HN users. - Onboarding test + one daily question before accessing feed, post or reply. - Posts authors are anonymous until upvoted or downvoted, forcing evaluation of content on merit. - Face ID (on-device only) to post/reply, pangram checks for AI text.

Sourcing good questions turned out to be much harder than I thought.

If you have suggestions to scale this, I would love to hear.

Eventually, could be gated across disciplines/topics to get a competence × interest graph instead of the pure interest graph of today’s social networks.
