Lesson 21 of 22 · 12 min
The traps that turn literacy back into tips
Recency is not a lapse of attention — three months of data pins a drift to ±32%, and 256 years are needed to tell 7% from 5%. The sample does not contain the answer.
What you will be able to do
After this lesson you can compute how long a sample would need to be to support a claim about drift, explain why searching for supporting evidence always succeeds and therefore cannot be evidence, and describe the ordering fix that works where willpower does not.
Inside this lesson
The last path feels like the law
When you catch yourself saying always
You will find a node that agrees
Paper courage, and the fixes that actually work
This lesson is on Scholar
Audit includes orientation and the two-rooms lesson. The rest of the path is paid course access — still education, still not advice.
