The scientific community is increasingly concerned with the proportion of
published “discoveries” that are not replicated in subsequent studies. The field
of rodent behavioral phenotyping was one of the first to raise this concern, and
to relate it to other methodological issues: the complex interaction between
genotype and environment; the definitions of behavioral constructs; and the use
of laboratory mice and rats as model species for investigating human health and
disease mechanisms. In January 2015, researchers from various disciplines
gathered at Tel Aviv University to discuss these issues. The general consensus
was that the issue is prevalent and of concern, and should be addressed at the
statistical, methodological and policy levels, but is not so severe as to call
into question the validity and the usefulness of model organisms as a whole.
Well-organized community efforts, coupled with improved data and metadata
sharing, have a key role in identifying specific problems and promoting effective
solutions. Replicability is closely related to validity, may affect
generalizability and translation of findings, and has important ethical
