Byqqa isn't a pep talk with a streak counter. Every mechanic in the sprint exists because behavioral research says it moves people who are stuck. Here is the whole system, with its sources, and exactly where each piece lives in the product.
Deciding in advance when and where you'll act ("implementation intentions") roughly triples follow-through versus intention alone, with a medium-to-large effect (d = .65) across 94 studies.
People given evenly-spaced, binding deadlines performed better than people free to self-pace, and self-set deadlines only worked when they had teeth.
Behavior happens when motivation, ability and a prompt meet. Motivation is unreliable, so the lever that works is shrinking the task until ability is never the blocker.
Procrastination is short-term mood repair: avoiding a task that makes you feel anxious or judged. The fix isn't discipline, it's lowering the emotional cost of starting.
Behavior sticks when it casts a vote for the person you believe you are. "I am a builder" outlasts "I should do my task".
Losses hurt roughly twice as much as equivalent gains feel good. Commitment devices put something real at stake so quitting has a cost.
People reliably re-engage at temporal landmarks: new weeks, new months, day one of anything. Guilt-framing after a miss does the opposite.
You learn what you retrieve and articulate, not what you merely experience. Writing what happened beats having done it, for memory and for judgment.
These are the best-evidenced techniques in the habit and motivation literature, but no study tested this exact combination on idea-people. That test is the sprint itself, and your results are the data. We'll publish ours as the cohort grows.
