G2 Science K223, K224 and K225 explanations need time as well as cause. A factor can change now while the measurable response appears later. If learners check too early, a real effect can look absent; if they check only at the end, they can miss a transient peak or recovery.
This one-hundred-and-nineteenth Learner’s Guide develops response-lag control. It extends Vol 0115 Baseline Drift and Vol 0111 Rate Versus Amount.
The lag question
Ask when the cause changes, when the mechanism begins, when the detector could first see the response, when the response peaks and when it settles. These times need not be identical.

Final rule
A cause can be real before its effect is measurable. Put cause, mechanism, detection and recovery on a time axis. Then judge the result at a time window capable of showing the process you are testing.
