Normal: Each person has their own definition

     It isn’t unusual for someone to say “that’s normal” or “that’s not normal”. But what do they really mean by that? What is this standard of normal to which they are comparing to whatever it is that they are noticing? “Normal” is what is normal to the person doing the perception. If I see something that would be something that is normal to me, then I might say “that looks normal”. It is possible that, if I know the other person well enough to know their regular habits, I might still say “that looks normal” even though it might not be normal for me. In whatever manner, the word “normal” will not have a single definition.

     Each person has their own “rituals”. This doesn’t necessarily mean religious behaviors (though it might). For example, I get up in the morning, use the restroom, inspect (and usually have to clean) the kitchen, get caught up with mail and social media, get hot tea and breakfast for my wife, and then do my morning language lessons (currently Spanish). And on it goes. But that schedule may seem extraordinary, strange, or peculiar to someone else.

     Our personal definition is based from our own histories. If I grew up as an orphan, I would have a different baseline from someone growing up in a “nuclear” family. Each would consider their own life to be normal — and the other person’s life something about which one might read in a book. If I was home-schooled, I would avoid certain experiences that someone attending a public, or “private”, school would expect to be as a part of their day. The other people of the household would have their own routines which interact with everyone else’s. And this combination will become unique for each person.

     Much of the time, these activities done by all the people interacting together are innocuous. But not necessarily. Alas, a child who grows up in a household in which they, or other members of the household, are abused in some manner will also consider that behavior to be “normal”. Unless corrected in their perceptions, they will grow up to consider the behavior as “something that everyone does and may have happen to them”. So, it is completely natural if they perpetuate the behavior with the people in their later-formed household. They would not consider it to be “abuse” — they would consider it to be “normal”.

     People are also influenced by their environment. On an island of Hawai’i, a school child may find it normal to go swimming, or surfing, on their way to, or from, school. That would certainly not occur to an Inuit who might be walking home across the snow and packed ice. Of course, since I grew up in a different environment from either of these children, I don’t really know what they would do or what they would each consider to be normal.

     Within the US, income class will make a huge difference between what is considered normal for a person. It will make a difference elsewhere in the world also but it may be cross-referenced with another social system such as caste or level of nobility. The behaviors, and expectations, within that group will seem “normal” to those who live within it — and the behaviors of those outside of that group will either be elevated or denigrated depending on perspective about those outside of the group.

     Although “rags to riches” stories do exist, it causes internal strain, and strains within relationships, when a person moves from one segment of society to another — even if they have “risen” in level. And it is very difficult for a person in one societal segment to truly represent, or understand, other segments because they live within different normalities and have very little insight into that of other segments.

     While it somewhat depends upon physical and cultural environment, people will do different activities. These activities will be different based on their histories, what resources are available, and their interests. Surfing, ice fishing, going to a mall — normal to the person doing it and, perhaps, quite exotic to someone else. A normal activity to one person may seem exotic to another.

     A child growing up in a war zone is in constant flux. There is little they can rely upon. Their house may be gone the next day — or a parent or sibling. There is no security possible. A child goes to school one day and is a refugee the next. This high aspect of instability must affect the perspective, and behavior, of the child. But it would still be normal to them. In older days of medicine — and still in too many segments of the world society — a large percentage of children died before they were a couple of years old. It was sad for all, but expected and “normal”.

     In my household a number of years ago, we adopted (or she adopted us) a cat from an animal shelter. We did not see her much for the first three weeks after we brought her to our house as she immediately ran for the back of our refrigerator as soon as we released her from the carrier. She did eat, and drink, as such resources would disappear overnight — but she had a huge readjustment to her own personal “normal”. I am sad to say that, after ten years with us, some of her baseline characteristics were still present.

     “All the world is a stage and we are only players”. A rich, well-nourished, male child in a stable city with easily accessible parents will absorb a very different normal from that of a poor, malnourished, female child surviving in a war zone.

     It is a cliché to say “walk a mile in another’s moccasins — yet it is still true that everyone has their own individual “normal”. We may have judgements on the other normals but they may have arguments, of equal weight from their points of view. of “incorrectness” of your own behavior.

     As long as the thoughts, behaviors, and actions do not impinge upon another’s ability to follow their own normal, it is best to just recognize that each person is unique and what is normal for them is what they expect to do.

     “Normality” only exists as a unique attribute that applies to each of us.

Is Being Average "Normal"?


     Many people are fascinated by surveys and tables of statistics. They can be fun -- and even useful, when interpreted by people who know what the data does, and does not, indicate. They can also be misused by presenting data in such a form that people will jump to conclusions that are not really supported by the data. This is done directly by many politicians and for political purposes and causes.
     I have mentioned before the quote popularized by Mark Twain -- "There are three kinds of lies: lies, damned lies, and statistics." I like statistics because I am fascinated by numbers. Their relationships and the ability to use various formula upon the data is a lot of fun. But I don't have sufficient training to use (or misuse) them properly.
     But this particular blog is not about such weighty matters. It is more about how people can take "everyday" data and make more of it than what they deserve. In particular, it is about averages and the definition of normal. An average is a fact when you are dealing with numbers. The average of two, five, and eleven is six.  The average height of a human male in the United States is approximately 69.7 inches (177 cm) -- but there are not that many men in the United States who are exactly 69.7 inches tall. In other words, few men are of "average" height.
     Averages only make sense for characteristics when you examine them within a distribution. A normal distribution curve looks like:



     Normal means, basically, that the curve has a uniform change throughout the graph -- there are just as many above the average as there are below the average and the percentages change consistently on both sides of the "bell curve". This ideal curve doesn't occur that often in nature. One problem that happens is that there are often assumptions that a distribution of data will meet a normal distribution without doing a sufficiently wide sampling of data to justify it. For example, the data for men and women's heights in the U.S. can look like:



     Note that the peak for men ends up around 70 inches, while the peak for women is at about 64.5 inches (164 cm). The peak is higher than for men and the curve is narrower. This indicates that women's heights don't vary as much as men and concentrate at the average. However, in both cases the curve is very "smooth" and symmetrical. For height, it seems that the data really does seem to support this -- with a longer "tail" at the tall end indicating a slightly greater number of very tall people versus the number of very short people.
     Any characteristic that can be measured can have an average. Skin color is based on the amount of pigmentation from different types of melanin in the skin. There could be an average value for this. The average weight for a U.S. male (in 2015) was 195.5 pounds (88.5 kg) -- an increase of 30 pounds (13.5 kg) since 1960. The number of hair follicles per square inch can be measured -- thus, there is an average value for "hairiness". Ear size can be measured from top to bottom (or front to back or distance out from the skull).
     How many people have an average height, weight, skin color, hairiness, and ear size? Probably only a half dozen or so within the United States. Are these six people the "normal" ones? No, not even from a statistical sense because there are going to be many other measurements that are potentially able to be done -- eye color, IQ, foot size, hand span, distance from bottom of nose to top of lip, and so forth. Everything that can be measured can have an average -- but none of them are "normal" because humans are not just one characteristic. They are combinations of many, many characteristics and there may be some that are genetically linked (if you have one then you also have the other) but most appear to be totally independent. Skin color is totally independent of IQ. Eye color appears to have little to do with height. Weight and height do have some correspondence but it is possible to have a tall thin person as well as a short heavy one.
     Since being average in every possible measurable area is highly unlikely,  it is certainly not normal to be average.

Lazy, lazy, tests: They are fast, easy, and non-invasive but they should never be solely relied upon
