Confirmed. Felps, Mitchell, and Byington (2006) published in Research in Organizational Behavior, Vol. 27, pp. 175-222. Their study of ~40 groups found a single bad apple reduces team performance by 30-40%. The paper combined literature review with experimental evidence, so 'demonstrated experimentally' is accurate though the paper is broader than just an experiment.
