The article title says:
"Study of pet dogs shows breed does not predict behaviour"
While the paper states:
"Breed is not a reliable predictor of individual behavior"
If it needs to be spelt out: The former implies no correlation between breed and behavior, while the latter explicitly says that breed does not reliably predict an individual's behavior, it could be a pronounced bell curve but you still have outliers.
So yes, the article title is obviously wrong and any sane person should trust their gut over it. And what is actually stated in the paper (not mentioning the conclusion because it doesn't have jack to do with the article title) in relation to this article's point is an obvious observation: It doesn't hurt to have data on, but is pretty much pointless for anything except producing bullshit, misleading, clickbaity pop science articles.
Even the article itself recognizes that there's a significant correlation between breed and certain behaviors, but merely dismisses it as "smaller than expected".
