Control Variable Method
An experimental design method that isolates the independent effect of a single variable by holding other variables constant and varying only that variable. In benchmark construction it is used to separate the effects of linguistic form and cultural context.
Timeline (last 90 days)
The two versions are completely identical in mathematical structure, with cultural context as the only variable; this controlled-variable approach can isolate the independent effect of cultural localization.
Debugging portrait prompts should use the controlled-variable method: fix the seed or initial prompt, change only one instruction at a time (composition, background, or lighting), and record cropping changes and similarity.
If you change several instructions at once and then compare results, you cannot attribute the cause of the change; for editing tasks you should also pay extra attention to "unexpected change" areas that the model altered without being asked.
