Regression Toward The Mean: illustrated.

There’s a concept you’re liable to encounter if you linger around the HBDsphere long enough.

It is often cited as a reason that having unusually intelligent parents (or parent) does not result in offspring who are also unusually intelligent. It’s a simple statistical/genetic principle. If a subject is of unusual statistical status (at the far reaches of the bell curve), odds will dictate that his progeny will typify a standard-leaning manifestation of the phenomena in question. The same can be said of other physical, inherited traits, as well. Height, strength, speed, stamina – essentially, regression toward the mean, as applied to human genetics, simply tells us that there is a predisposed human tendency to be “normal” and that if your parents are abnormal, chances are that you will be more normal than they because it is nature’s default dispersal field.

In addition, I wonder how many other unidentifiable genetic traits might fall in this category. Musical talent, mathematical skill, coordination, social skills, charisma, depression…all alike are probably grounded in a genetic blueprint.

I thought of this in the wake of Bobbi Kristina Brown’s physical travails the past 2 weeks after being found face down and unconscious in a bathtub on January 31. In a scene eerily similar to that of her mother, Whitney Houston, from three years ago, Brown was rushed to the hospital and has been straddling a comatose death state since.

I haven’t kept abreast of the story much. It’s not the kind of thing I pay attention to. All my exposure and knowledge about the Brown tragedy comes secondhand from women I know who care about this TMZ-style news and state of celeb current events.

It has, however, also prompted me to consider “regression toward the mean.”

Every time I see a photo of Whitney Houston and Bobbi Kristina, I see this statistical rule embodied in the mother-daughter lineage.

Regression toward the mean no longer needs to be defined. We have an illustration.
