This FORS Guide discusses how methodological practices and dissemination policies are
likely to produce cumulative filters throughout the survey life cycle, acting as barriers to the
representation of uncommon social experiences. A reflexive approach is proposed to
researchers to observe how and why some of these filters make it less likely that minority
populations become study samples, that non-normative events are reported by participants or
noticed by researchers, and that “atypical” data are not stored, shared, and reused. This guide
has been developed by members of the 'Data diversity and public good research’ group within
the FORS-SSP scientific research program
