What I Would Fix First About Idea Filters
Three changes that lift filtering quality fast.
Fix 1: Make Filters Binary
No "maybe." Yes or no per filter. Maybe is how favorite ideas survive that should not.
Fix 2: Reachability First
Not last. Reachability decides how fast you learn. Move it to the top of the list.
Fix 3: One Outside Reviewer
Spend 30 minutes with someone outside your circle. Their no on your favorite idea is the most valuable data point of the week.
What Stays the Same
The filter list. Four filters, same questions, same order. Do not redesign. Just use it honestly.
