A habit is more than how often you do it
Read what the habit index measures. Then ask the same questions about your own pattern.
A habit is how often, how automatic, and how much it feels like you.

HOW STRONG THE EVIDENCE IS
MODERATE. Four studies that built and checked a questionnaire. It gave steady results across repeat tests.
“We argue that habit is a psychological construct, rather than simply past behavioral frequency.”
Counting a habit misses part of it. This paper built a way to measure the rest.
The Research Library reads one paper at a time and says what it found in plain words. For this note we read the abstract, not the full paper.
What the research found
The authors argue a habit is more than how often you do something. Across 4 studies, they built a 12-item questionnaire to measure it.
The questions cover three things. How long you have repeated it. How automatic it is, meaning done with little control or awareness. And whether it feels like who you are.
The scores held steady when people took it twice. They also matched how often people did the behavior.
The index could tell daily habits from weekly ones. The authors say it can track habit strength without counting every time.
How strong the evidence is
This is a measurement paper. It shows the questionnaire gives steady and sensible scores.
It does not test how to change a habit. It gives researchers a ruler. The habit study on how long habits take used this same ruler.
What it means for catching a pattern
The Disappearing Pattern is the pull to leave when someone gets close. You may count how often you go quiet and think that is the whole picture.
This paper suggests two more questions. How little awareness do you have when it starts? And does it feel like just who you are?
Catch works on the first question. Catch means you feel the body signal and name the pattern before it becomes the behavior.
The body signal is what you feel in your body as the pattern starts. Each time you notice it, the pattern runs with a little less of its old blind spot.
What it does not show
This paper did not test The Archivist Method. It built a questionnaire for habits in general.
A high score does not mean something is wrong with you. It measures how automatic a behavior is, and nothing more.
The free Crash Course, short lessons on your pattern, starts by naming it.
