"Experimental research found contradictory results regarding the occurrence of Informational Cascades. While Anderson and Holt (1997) through lab tests confirm the model of Banerjee (1992), and Bikhchandani, Hirshleifer, and Welch (1992) resp., Huck and Oechssler (2000) come to controversial results for crucial issues. This study is an extensive (227 test persons) and as regards contents expanded repetition. It becomes obvious that less than 10% of subjects are able to make deductions from predecessors' actions regarding their private signals, to consider the reliability of the signals and the a priory probability, to accurately use Bayes' Rule, and to thus reach rational decisions."
