Event organizers often struggle with inaccurate attendance estimates because the current Facebook RSVP system forces binary choices that don't account for genuine ambivalence. Many guests hesitate to commit prematurely but also avoid outright declining, leaving hosts uncertain about real turnout numbers. A third "Interested" option exists, but it's frequently misused as a non-committal response rather than expressing actual interest.

A More Honest Middle Ground

One approach could be introducing a "can't be arsed" option alongside existing RSVP choices. This would:

• Give guests a truthful way to express disinterest without social awkwardness
• Provide hosts with clearer signals about potential attendance
• Reduce pressure for early commitments while maintaining engagement

The feature might include automated reminders as events approach or tools for hosts to gently nudge undecided guests. Unlike the vague "Interested" option, this would specifically capture those who are unmotivated but might attend with proper encouragement.

Pathway to Implementation

Starting with a browser extension could test demand without requiring Facebook's involvement. This MVP might:

1. Add the new RSVP option to event pages
2. Track responses through a simple backend
3. Show aggregated data to hosts using the same extension

If adoption grows, Facebook might consider integrating it natively with their event system. Alternative phrasings like "Meh" or "Undecided" could make the feature more universally acceptable if "can't be arsed" seems too informal.

Better Data for Better Events

The system would help hosts by distinguishing between genuine interest and polite disengagement. Unlike external tools like Doodle polls, it would work within Facebook's familiar interface while solving a specific social pain point that existing options don't address. Over time, the additional response data could help both hosts and Facebook understand actual engagement patterns more accurately.
