Do we understand numbers?

As of Tuesday, Kamala Harris and Donald Trump made their final pitches for victory.  Now, as Americans from coast-to-coast cast ballots, polls showed a razor-close election likely to come down to seven top battleground states: Pennsylvania, Michigan, Wisconsin, North Carolina, Georgia, Nevada, and Arizona.  We still don’t know the outcome …

This past year of nonstop political nonsense on both sides of the isle has convinced me that Americans failed math … almost everyone. Nobody understands what the average of anything means. They don’t understand the most likely events, nor do they understand the importance of the “tails” of the distribution … things that are not “likely,” but still happen.

Even when I tell the story of our timeshare in Cancun that was hit by Hurricane Gilbert the year after we bought it. We were feeling pretty good that hurricanes don’t hit that part of Mexico because the salesperson properly quoted that “Cancun had not been hit by a hurricane in 37 years.” At the time, I viewed that with some level of comfort, but in retrospect I should have assumed “we are due,” and would have been correct.

No one seems to appreciate the risk of using numbers to make certain types of decisions. The pre-election polls always indicated the country was about evenly divided between republicans and democrats … and that my friends is a important part of our democracy in that it can create checks and balances on just about everything in our lives. Conservatives like myself have been terribly concerned that the progressives’ rightful leanings need to be considered, but should flatly be denied in areas that affect our public safety.

Therefore, I firmly disagreed with the defunding the police and the idea that some jobs just need diversity in their constituent base other than excellence in talents in abilities. Go ahead and try to rebalance areas where public safety isn’t critical to experiment with new ideas, but please leave pilots, physicians, engineers and others who must have excellence in their abilities alone to properly execute their jobs.

What truly surprises me is the complete lack of appreciation for averages and the distribution of outcomes underlying those averages. The average seldom represents very many people. There are about equal numbers of males and females, but relatively few can be defined as an average … although we seem to be obsessed with these deviants in the mathematical distribution.

No, all too many today will want to quarrel with me on my last label about people who can’t quite decide whether they are male or female because some progressive thinkers now want to offer these deviants from the normal distribution their special spot in the sun.

Yes, these individuals have been marginalized in the past and been the target of hate, but I might remind everyone that I grew up with that kind of hate because I was a geek … a nerd. Our son was bullied by the quarterback of his high school’s football team … so everyone looked the other way … because on average, winning the football games mattered more than doing the right thing.

Averages work well to understand the risks at things like gambling where the odds are useful to predict the likely outcome of repeated bets on a certain strategy. Yet, while the odds are clearly against everyone, since it is a business and the “house” has to make money on average, people repeatedly flock to this activity that is just stupid because of the opportunity and thrill of winning occasionally.

Perhaps that is the summary. Everyone seems to be looking for the adrenaline rush of that occasional win rather than playing a game where the odds are stacked against us. Maybe the thing we call our democracy is nothing more than a game of craps where we just cheer wildly when we win and then keep betting in the hope our horse will come in.

It is funny how we characterize each other to make ourselves feel better. The optimist says the glass is half full and the pessimist says it is half empty. We engineers feel righteous in reminding everyone that there appears to be twice as much glass as we really need.

  1. The difference between “median” and “average” is profound, and yet that bell curve graph is stuck in our heads so we perceive the average as the norm.
    My medicines are routinely prescribed for the average result and/or reaction for my age. I also routinely question this since I’m not average. More people are in the slopes of those graphs than the so-called average at the top of the curve. So when drugs are tested and approved for the “average”, they often are total duds. Oops.
    You can’t expect average reactions. The “slopes” of the bell curve voted. Supposed to be a close call… nope. They forgot about the median. Most of America.
