TL;DR: After submitting 240 PRs to 50+ open source repos and tracking every single outcome, I discovered that getting merged has almost nothing to do with code quality. It's about psychology, timing, and understanding the invisible social contracts that govern open source. Here's the data, the patterns, and the playbook that took my acceptance rate from 15% to 45%.

The other 43 repos? Zero. Nada. Not a single merge, despite submitting 89 PRs to them. This isn't a code quality problem. It's a psychology problem. The Invisible Social Contract Every open source repository operates on an invisible social contract — a set of unwritten rules that determine whether your contribution will be welcomed or ignored. After analyzing my data, I identified seven psychological principles that govern PR acceptance: 1.

This "mere exposure effect" is one of the most robust findings in psychology. In Open Source: Maintainers are far more likely to merge PRs from contributors they reco
