G2 Science K223, K224 and K225 usually asks learners to connect current conditions with current outcomes. Sometimes the current condition is not enough: the system’s history matters. Two samples can face the same input now but respond differently because they arrived there by different paths.
This one-hundred-and-twenty-third Learner’s Guide develops path-dependence control in an examination-friendly way. It extends Vol 0119 Response Lag and Vol 0115 Baseline Drift.
The path-dependence question
Ask whether the present output is determined only by the present input, or whether starting state, previous exposure, accumulated change or incomplete recovery also matters. If history matters, record it as a variable rather than treating two present conditions as identical.
1. pre-heated versus cold sample
For pre-heated versus cold sample, compare two systems with the same current input but different histories. Predict whether the histories could leave different internal states even when the visible current condition matches.

Path dependence is different from lag and drift
Lag means the response takes time after a change. Drift means the reference condition moves with time. Path dependence means the route taken to the current state changes the response. These mechanisms can coexist, but they imply different experimental repairs.
Order effects are a practical clue
If A-then-B gives a different result from B-then-A, treatment order may matter. Randomising or counterbalancing order, using fresh samples or verifying return to baseline can test whether the first condition changes the second.

Final rule
When two systems face the same input but respond differently, ask whether they truly started from the same state. Present conditions matter; sometimes the route into those conditions matters too.
