Loneliness and a specific pattern the researchers call fear of missing out turned up as common, recurring themes rather than isolated complaints. What they do establish is that the isolation solo travel can produce is not an occasional glitch in an otherwise frictionless lifestyle. The research on digital nomads suggests this absence produces loneliness often enough to be a recurring, documented theme, not an occasional bad week. The travel risk research draws primarily on self-reported perception rather than incident data comprehensive enough to state a precise likelihood of harm for any specific traveller in any specific place. Neither literature offers a verdict on whether solo travel is worth its documented costs for any individual reader, which depends on factors this research was not designed to weigh.
