This paper opens the issue compiling a series of experimental studies
on variable agreement in Russian. The agreement variation is not integrated
into grammatical models due to the lack of any systematic approach
to collecting data on the effect size and scope of relevant grammatical factors.
We discuss methodological problems related to the study of agreement
variability, and present case studies published in the special issue. We show
that one of the possible solutions to the problem of including variability
phenomena to the empirical basis of formal syntax is to use the methodology
of experimental syntax
