Chronotype: what it is and what it means

An individual chronotype is the biological disposition that determines at what time of day a person performs best on demanding cognitive tasks. Cognitive performance varies by time of day and by individual chronotype: forcing someone else's schedule on yourself means working against your own biology. The mechanism works as a filter: the same deep work block placed at the wrong hour for your chronotype produces lower-quality output than at the right hour.

Distinctive: biological disposition
