This seems more like a Skeptics kind of question, I don't really see it framed in anything related to psychology or neuroscience. Maybe you can clarify?

@BryanKrause; I've already clarified that I'm looking for controlled "laboratory" experiments, as typically done in psychology studies.

Try to change the label to social psychology and prejudices. it's possible the control in a sense methodology but the causal control of xenophobia by researchers is not possible, in this way there is no "controlled laboratory experiments". On the other hand it is not a "halo effect" but influence.
