The Trouble with Numbers
For example, for most people, the date today is
Unhappily, the same lack of understanding lies behind so many of the numbers we use in society today, and the numbers tend to become "reality," with little understanding of what actually lies behind them -- until something goes wrong, and the blame is assessed everywhere but where it should be -- and that's at a lack of understanding of what the numbers really mean... or, in many cases, what they do not mean or represent. For example, everyone takes "for granted" that if someone runs a temperature over 98.6 degrees Fahrenheit consistently for several hours, that person is sick. Not necessarily. In some cases, subnormal temperatures signal severe illnesses as well. Also, the 98.6 degree number is an average across large populations. It doesn't hold for everyone, as I well know, because my wife's "normal" temperature is consistently a degree and a half below "normal." What that means for her is that what would be a mild or moderate fever for someone else is a severe fever for her. Yet the failure to understand the difference between "normal" for her and for the population as a whole could make a considerable difference to her in the case of a severe infection. I've made the point earlier about numbers in regard to the side-effects with regard to vaccinations. Because some parents do not understand statistics, because they fear side-effects that occur in one in a million cases, they will avoid vaccinations for "childhood" diseases, where the side effects of the disease are often hundreds of times more prevalent than the side-effects of vaccination. Failure to understand what the economic numbers meant in the several years before the last financial meltdown contributed mightily to the disaster. No matter what any "guru" preaches, you cannot have massive societal and even world-wide price run-ups in securities and real estate prices on a wide-scale basis when real overall economic growth is slow or moderate -- not without generating a "bubble" and a subsequent collapse. Nor can every company realistically aim at 10-40% annual profit targets, and when large numbers of companies are posting such profits at a time when nominal inflation is low... something is wrong, either the way those profits are calculated, or the way inflation is measured... or the reporting of other data... or the business practices of the companies involved. Likewise, when more than forty percent of the grades given at universities in the When "reader reviews" flood Amazon.com, what do they mean? Do they really judge excellence? While some may be accurate in that regard, in practice what those numbers reflect is popularity, not quality. There's nothing wrong with that... so long as people understand that, but unfortunately, many don't. More than a few readers have contacted me in surprise after reading one of my "less popular" SF novels to say that they thought a book was far better than the reader reviews. That shouldn't really be surprising. Often excellent books do not make a quick and easy read, and for some readers, who seek ease of escape and entertainment, an excellent book may not be a good read. That doesn't mean the book is "bad," only that it's not suited to them, but handing out "stars" for popularity doesn't reflect quality. In fact, one reader made the point that he looks for "bad" ratings among authors he knows are good writers to find the excellent books. The same problem exists with the travesty of "student evaluations." I'm sorry, but 18-20 year old students do not know what they need to learn. Studies have shown that high student evaluations correlate directly to high grades given by the professor. There are always exceptions, but across thousands of professors that observation holds true. Thus, the numbers reflected in student evaluations do not reflect the quality of teaching, but the degree of grade inflation. Yet university administrations routinely use these evaluations as a proxy for good teaching. What their use reflects is not excellence, but the need for "popular" teachers to fill classrooms, regardless of excellence. I could go on and on, but my opening thought for another numbered year is that, with more and more numbers flooding us, day after day... try, please try, to understand what they really mean and not what everyone else tells you they mean.
thanks for the promt response, I guess I was trying to see if the same responses that occur in a social group--everyone picking up cultural norms of behaviour even under conditions when most remain illiterate--could be used in the aid of teaching complex theory. Thinking on your reply, it occurs to me that perhaps I should have asked if teachers should be percieved to hold more power within society then currently, maybe by assigning military aids to them or they holding some rank within the military.
I forgot to say Happy New year last time, so Happy new year, and I wish you and yours well.
