Can you elaborate on why you believe this to be the case? Saying that a scientist is one who does science seems like a truism bordering on being tautological. I'm curious why you disagree.
"Scientist" implies a certain amount of knowledge, training, discipline, etc. I'm not implying that every scientist needs to have undergone academic training - there are other ways - but merely doing a scientific experiment is not enough to call yourself a scientist.
A scientist is one who "does science" with some knowledge, consistency and perseverance.
> In a more restricted sense, a scientist is an individual who uses the scientific method. [...] This article focuses on the more restricted use of the word.
If we're going to throw definitions around, how about dictionary.com: http://dictionary.reference.com/browse/scientist?s=t
> an expert in science, especially one of the physical or natural sciences.
If being a scientist is determined by the consensus of one's peers, it seems like it makes sense to accept an article defining what scientists are that is written as a consensus opinion.
But anyway, if you think it's wrong, why don't you edit it?
