Lett, G. S. 2010. Measuring the impact of animal enrichment on research results. Enrichment Record 2, 6-7.

My take on this message is that the research community is gathering enough data from laboratory animals under a variety of environmental conditions, but we are not recording and/or sharing enough information about the animal treatment part of the experimental protocols to use this data to help us learn what constitutes optimal conditions for animals and the research they support.
