The fear that seeing naked people in some way harms children is not supported, however, by academic research. The small handful of studies on this topic in psychology and sociology have shown, instead, that children reared in an atmosphere containing family social nudity may benefit from the practice. If this is true, then proposed laws outlawing either social nudity in the home or children’s participation at naturist (or nudist) settings are unjustified.
