No, it's not incorrect, you just failed to understand my point. You are isolating this study from other research and taking it at face value, whereas I am putting it in the context of substantial previous work and knowledge.
Imagine there were a study that correlated people letting go of things and those things falling to the ground. Taken at face value, as you do with this story, one should ask, for example, whether something else caused both the letting-go and the dropping-to-the-ground. But taken with previous knowledge, that would be an exercise in pointlessness; we all know what gravity is and that it exists, and so we can conclude that letting go of things is in a causal relationship with those things falling to the ground.
In other words, pedantry doesn't do anyone any good here, because we already have substantial evidence applicable to this new work. I appreciate your and the community's attention to correctness, but in this instance, it's being misapplied.
