CONS∃NSUS is a public-domain software package.

CONS∃NSUS is developed to carry out a behavioral social choice analysis, to answer several questions: What types of preferential data do the sources provide? How do the observed data relate to latent (unobservable) preferences? Which mathematical consensus algorithms are of interest? Given a set of expressed preferences, does a unique consensus option exist? Does the consensus outcome depend on the aggregation method? Does the consensus outcome depend on assumptions made in the analysis? How robust is the consensus outcome to uncertainties in the data? How does the consensus outcome depend on the number of sources probed? We provide a new public-domain software package, CONS∃NSUS. This program makes it easy for scholars and practitioners to compute, evaluate, and compare the results from multiple consensus procedures.

CONS∃NSUS Software

In order to use CONS∃NSUS you will need both an MCR installer and a compiled version of the CONS∃NSUS software program, both of which can be found below. First, download and install the MCR installer. The MCR installer only needs to be installed once on your computer. And it must be installed on all platforms. Second, download a compiled version of  CONS∃NSUS. Whenever you would like to start a new instance of CONS∃NSUS, simply open this CONS∃NSUS file.
