Said Camilla Kring, quoted in "Late sleepers are tired of being discriminated against. And science has their back. Some people have a biological clock naturally set to a later time" (Vox). Kring founded the B-society, "an international advocacy group calling for increased acceptance of the evening-oriented."

“Just by changing your schedule by an hour or two, it can result in having more sleep, higher productivity,” she says. In this view, workplaces ought to be more accommodating of chronotypes.

The research generally backs this idea up. “Although we should avoid a simplistic shortcut of associating ET [evening types] to some negative aspects, the data point to the idea that an [evening type] pattern is a risk factor for some disorders, whereas [morning type] is a protection factor,” a 2012 review of hundreds of papers in the academic literature concludes.

Different orientations are not just about sexual preferences, and the differently oriented have infinite demands for accommodation.
