Show HN: I Built Paul Graham's Math/Logic CAPTCHA Idea for Social Media

1 point

a month ago

PG has posted many times about improving social media discussions using an "intellectual CAPTCHA" or simple math / logic test [1][2][3][4] - "I have often sensed that a really easy math CAPTCHA would improve conversations about economic inequality.", "Make users pass a test on basic concepts like the distinction between necessary and sufficient conditions before they can tweet."

I built one using a mix of simple math, logic, reasoning questions from social media posts and retired standardized test questions. This is not a CAPTCHA in the traditional sense. The goal is not to stop AI, but to allow users to participate in discussions.

- Invites are temporarily open to HN users.

- Onboarding test + one daily question before accessing feed, post or reply.
