They say they cannot read anymore. Give them a 300-page novel and they may abandon it after 15 pages, reread the same paragraph repeatedly or suddenly reach for their phone. Yet the same person can spend an hour reading relationship confessions, Reddit-style anecdotes, celebrity stories, news explainers, personal essays and psychological posts on social media. The contradiction is revealing: perhaps they have not lost their interest in reading at all. Psychology and reading research suggest the difference may involve sustained attention, cognitive load, fragmented reading, task-switching and digital reading habits. Short online stories repeatedly provide quick beginnings and endings, while books require the reader to maintain attention, characters, ideas and context over much longer periods.
The important caveat is that research does not prove social media permanently shortens everyone's attention span. It does show that the way information is presented can influence how we allocate attention and process what we read.
