>Well, yeah. Psychology and sociology aren't true sciences. They're kinda like what statistics is in the math world.

They can be more and less rigorous. This isn't a _terrible_ paper - its from a good place, they actually did the experiments in two different contexts, with different subjects, and the numbers of participants were reasonably good.

On the downside, "avoidant attachment style" and "feeling appreciated" are far from being objective criteria, indeed many of these kinds of behaviors are a matter of cultural norms . . .

. . . so read it for what it is, and be aware of the limitations.
