It is not clear why the users tend to ignore the extra relevant documents that are presented with the Okapi based systems. As such, two conjectures known as obscurity and distraction is discussed. Though, there is not statistically significant evidence to support either conjecture. If either conjecture holds, then the poor performance of the Okapi based systems can be attributed to the user interface employed in the experiments.
