Social displacement is the proposition that time spent on social media replaces time spent in face-to-face interaction, particularly with close friends and family, thus reducing well-being. There is clear evidence of growing mobile and social media use, and some evidence of a decline in face-to-face communication. This essay concludes, however, there is very little direct or causal evidence of social media time displacing face-to-face time. This article concludes that increasing social media use most likely displaces other media activities. To explain findings that seem to support social displacement, this essay examines the difference between population-level trends and within-individual behavior, and the difference between within-person and between-person displacement.

社会置换是指花在社交媒体上的时间取代了花在面对面互动上的时间，尤其是与亲密的朋友和家人互动的时间，从而降低了幸福感。有明显的证据表明移动和社交媒体的使用正在增加，而一些证据表明面对面交流有所下降。然而，本文的结论是，几乎没有直接或因果证据表明社交媒体时间取代了面对面的时间。本文的结论是，增加社交媒体的使用很可能会取代其他媒体活动。为了解释似乎支持社会流离失所的发现，本文研究了人口水平趋势与个人内部行为之间的差异，以及个人内部和个人之间流离失所之间的差异。
