How we measure progress
What these exercises can and cannot tell you.
There is no IQ score here, and there will not be one
A single number claiming to summarise your mind would be easy to market and impossible to defend. We do not produce one.
Three separate things
Performance on the task
How well you do on the exercise itself. This is the one that reliably improves with practice, and it is the least interesting of the three.
Carry-over
Whether the gain shows up on a related exercise you did not train on. Sometimes it does, often only a little. We measure it rather than assume it.
Real-world use
Whether you managed to use the technique away from a screen. Self-reported, deliberately: nobody can verify it for you, and pretending otherwise would be worse than asking.
What we are careful about
Getting better at an exercise mostly means getting better at that exercise. Techniques such as chunking transfer further than raw drilling, which is why the Labs teach techniques rather than just serving repetitions. We state each Lab's promise as a measurable result on a stated task, never as a claim about your intelligence.
How a score is built
Accuracy carries the score. The speed bonus is capped at 12% of the maximum, measured only while you answer, and multiplied by your accuracy — so a faster phone or a lucky guess cannot buy a better rank. The observation phase is never timed for score.
How ranks are built
Everyone plays the same challenge on the same day. Weekly standings add up daily rank points, not raw scores, so a hard day never counts for less than an easy one.
