Evidence discipline
Every product claim separates established evidence, plausible interpretation, and what STACKS is testing for one person.
What we know
Directly supported findings, described without decoration.
What may be happening
Mechanism-level interpretation, labeled as interpretation.
What STACKS tests
Personal descriptive evidence that can outrank generic defaults over time.
Know
Specific if–then plans can improve follow-through in relevant settings.
Think
They reduce repeated decision-making when the anticipated cue appears.
Test
Which failure cue and response are useful for this person and Stack?
Know
Smaller entry commitments reduce the amount of behavior required before someone can honestly say they started.
Think
The permission to stop may reduce perceived effort before action.
Test
Whether reaching the minimum increases continuation for this person.
Know
Task-relevant external focus is supported in many performance settings.
Think
It may reduce unhelpful self-monitoring before precise or social action.
Test
Whether outward cues shorten latency or improve process scores in a specific context.
Know
Many performers use repeatable pre-performance sequences.
Think
Their value depends on function, context, and flexibility—not fame or repetition alone.
Test
Whether a transferred mechanism helps without becoming a dependency.
Excluded as foundations
Lucky charms, power-pose hormone claims, arbitrary ritual claims built on retracted evidence, outcome-only fantasy, precise dopamine-spike claims, universal habit timelines, and universal optimal-arousal levels do not justify product behavior.
