Akrasia
Acting against one's better judgment under the pull of a conflicting desire
Examples
He judged sleep more important and still kept scrolling, a small instance of akrasia.
Changing a plan after learning new facts is not necessarily akrasia.
Origin
The Greek term is often translated as weakness of will or lack of self-control. Aristotle examined the puzzle in Book VII of the Nicomachean Ethics: in what sense can someone know what should be done yet act otherwise? His analysis distinguishes possessing knowledge from actively using it.
How it connects
Akrasia names the gap between a better judgment and an action pulled elsewhere.
This word appeared in Knowing better and doing otherwise, the Involves connection for September 28, 2026, which asked: Why doesn't a good judgment always produce the action it recommends?

Which case most clearly illustrates akrasia?
Someone still judges stopping best but continues for immediate gratification. Exactly. Akrasia involves action against better judgment, not every change of mind.
What the sources establish
Aristotle examines acting against judgment and distinguishes possession from active use of knowledge.
