Night owls have advantages over early birds.

The results of this study add fuel to a fire that's been burning for awhile with me.

I've always taken issue with those who point to my tendency to rise late and stay up late. Our society, due to its Calvinist legacy, puts great stock in the dictum: early to bed early to rise.

My point is that late risers and early risers each have something to offer and to force one into the mold of the other is prejudice.

This recent study offers proof that being a night owl gives certain benefits.

Good.

Out groups not necessary for in group cohesion.

This study offers some insight into the "out-group homogeneity effect (OGHE)."

The OGHE is a cognitive bias found in all humans. Basically, a person tends to view people that are perceived to be different as more similar to each other.

For instance: If you perceive yourself as a member of a minority, then you are more apt to view those not in your minority as being all alike, e.g. "All white people look alike to me or all straight people are homophobes, etc."

The reality is that most people do not fit neatly into such bigoted boxes.
