The Gap Framework

Print this. It's the diagnostic you run on any hook.

what they
already assume
a crack in it
(the gap)
a pull to
close the gap

Build a hook (3 steps)

1 · Find the assumption What does your reader already believe about this topic? Write it as a plain sentence. ("Consistency is what grows an account.")
2 · Crack it Contradict, flip, or withhold part of that belief so a hole appears. ("Posting daily for a year, the consistency wasn't what grew it.")
3 · Hide the resolution one swipe away Make the answer feel close but not given. They must reach.

Diagnose a dead hook

Ask: is there a gap at all? If the answer is given, guessable, or unwanted → Failure 1: No gap. Fix: take the answer back out; find a belief worth cracking.
Ask: can they imagine an answer? If the crack is so vague it reads as a bluff → Failure 2: Gap too wide. Fix: shrink it, get specific, make it feel scratchable.

The sweet spot

Small enough to feel closeable. Big enough to matter. Both, or the pull dies.
