"We should be sure that the goals and results from any AI system continue to befocused on what we want to achieve, and that we transparently define thosegoals for anyone impacted."

The expected AI behavior in the experiment in the Infoscience article was that all communication would be suppressed to conceal the food location. As the article states "...this somewhat surprising result was due to the strength of selection in suppressing information declining concomitantly with the reduction in information content".
Illustrating the gap between machine behavior and human expectation, these kind of results should help focus development of AI to better reflect human behavior. Some interesting research in that area shows how the human body could be reduced to mathematical equations as anthropomorphism for machines. I expect treating the human mind in a similar way will be more challenging.
