I heard about an experiment that have shown an effect of the type of paper a resume was printed on, on the evaluation of the resume. If I remember correctly, resumes printed on heavier paper, or attached to heavier writing pads were evaluated as better.
I may have some of the details wrong (for example, it may have been some other job application forms, and not resumes), but hopefully the gist is right.
I tried to look for the reference, but couldn't find it. Does anyone know of a reference presenting such an experiment?
