Agreed. I see it as both a cultural thing as well as practical thing (perhaps what initially lead to it becoming cultural). The reason for the second part is because most analyses are not easily reproducible--they exist as a smattering of data files and analysis scripts that coalesce into a magical, undocumented pipeline that spits out statistics and figures. Reproducibility has received more attention lately but it's still an uphill battle against academics' frantic publishing schedule, lack of familiarity with their software, and general lack of incentive for others to replicate the results (for some, a reverse incentive exists).
