How it works
Named, corrected, wired together.
- STEP 01
A named failure
Each entry is one specific way good thinkers reach wrong conclusions — named, so you can spot it in the wild.
- STEP 02
The countermeasure
Every correction ends with the move that interrupts the trap: what to check, and the audit prompt to run it.
- STEP 03
One a week
A new full correction lands every Tuesday. Subscribe and the map fills in around you over time.
The weekly trap
One thinking error, corrected, in your inbox every Tuesday.
No filler. One trap, its mechanism, and the countermeasure. Free.
