I am unable to find that text in the article. I am even unable to find the word 'operator'.

In any case, I pointed out that there's a 3x difference between two houses, so I am in complete agreement with that statement. My post asks a different question, which is, what is the error range on the observed results? What are the odds that the stove doesn't actually have an effect on wood use, but that some other factor ('operator and the conditions of use') resulted in the observed differences?

Ah, sorry, tab mixup on my end, the quote is from another article linked in the comments below; http://www.lowtechmagazine.com/2014/06/thermal-efficiency-co...

Anyway, the question you pose is a good one.

I dont think so? They observed three families, but most likely told one of them all about the new amazingly efficient stove.

"The Hawthorne effect (also referred to as the observer effect) is a type of reactivity in which individuals modify or improve an aspect of their behavior in response to their awareness of being observed."
