A Matter of Magnitude - fun with statistics

Sometimes a statistic can be toyed with a bit to illustrate a point. Here's an example.

In spite of all the safety locks and procedures and requirements, the probability that you will die in any single roller coaster ride has not varied by even 1% in the last 50 years.
If you were to say that to a roller coaster designer I'm sure they would fight about it quite vehemently, quoting various alternative statistics and engineering feats of wonder. You might not be able to get a word in edgewise to explain it to them. But the simple fact remains, the above statement is completely and totally factual.

Let me explain.

At no time in the last 50 years has there ever been:
  • a zero percent (0%) chance of death in any one roller coaster ride
  • a one percent (1%) chance of death in any one roller coaster ride
The median is of course .5%. Assuming something between 0% and 1% for the average probability of death from any one roller coaster ride, then it has not varied by more than 1%, going below 0%, or going above 1%, in the past 50 years. The logic is of course sound and simple to prove. Ask any marketer and they would agree wholeheartedly in the soundness of that statement.

The next time you hear any statistics like that about events that do not adhere to the Bell Curve keep in mind that the author might be using fun math like the above to force it into a normal distribution model. They are taught this in school, rewarded for being able to force events into this model, and it makes quick, simple sense to the common folks.

I know these numbers are some % off, but assuming they are off the same %  in the same direction each time, I can judge my training relatively from day to day

A very long time ago when I was in Middle School a teacher was reading an alarmist article by a reputable and highly respected medical professional. The article claimed that 4% of all humans would die each year from some form of childhood or adult cancer and that nothing could be done to stop the slaughter. I raised my hand and asked "Does that mean that in 25 years the Earth will be devoid of humanity?" It put a whole new spin on the whole alarmist process.

Obviously, in 7th grade I wasn't ready to compound the % across the years, but at a certain point the reproductive capacity of the remainder would fall behind the spread of the cancer, since it was assumed all ages would be affected equally, having been given no information to the contrary. Death usually removes the recipient from the gene pool.

Speaking of no information to the contrary, there is an alarmist article going around the net currently that the majority of the people from Kansas believe that the Earth is the center of the Solar System. I would love to know the exact sequence of questions that arrived at that conclusion, and what the other percentages of people believed (Jordan? Jobs?), but one thing to consider is that the majority of Kansans have at one time or another gone to public school. If you were trying to prove that all money spent on Kansas schools was a pitiful waste, this survey would be the tool.

I highly recommend that you read The Black Swan: Second Edition: The Impact of the Highly Improbable Fragility" It's an excellent introduction to statistical events outside the Bell Curve and how they impact everything from politics to the insurance industry. I think you might enjoy it no matter what business you are in.

Every Book Holds a Little World Inside

When I'm in full on writing mode, I can crank out up to 10,000 words a day.That's not normal though. I try to set a goal of getting in 2,000 words a day, like the old Stephen King writing advice states. “I like to get ten pages a day, which amounts to 2,000 words." Stephen King Goodreads I got quite a few books written in a short time span last fall, then settled down into normal daily life. The intensity required to write a book like "My Sweet Infected" was unexpectedly devastating. I became my protagonist in so many ways as she crept into my psyche and took over for me as I channeled her every thought as I created the story of her awakening. Read the book if you want to know more about this ruined world with humans on the brink of extinction. Find the clues, sort through the chaos, and realize the end is inevitable. The little world inside this book is doomed. Check it out, get the free sample for your Kindle - On Amazon My Sweet Infected (My Inf...

Eternal Redemption - Review [#horror #fantasy]

Eternal Redemption by Paul A. Wunderlich My rating: 2 of 5 stars Rating this: under the little star at position 2nd from the left, there is a little balloon that pops up "It was OK" That's about it. In general, the tone and language seem like a fervent attempt to imitate high fantasy. There are a series of editing errors that cause some confusion. It's tough to write a protagonist who drifts in and out of their own head. Time slips around in circles. An entire world of minions is disposable. When you're sitting at the top of an Everest sized pile of skulls, what's the next big challenge? Oh, yeah, trick the master trickster. Well, you get exactly what you ask for. With a little syrup on the side. View all my reviews

Film Festival History

A very long time ago when I lived in Kansas City, I attended a workshop on how to write a screenplay. At the time I was already editing my own fanzine that I later sold for an outrageous profit. I was also writing regularly for a handful of local magazines including New Age and Health topics, like the kind you find in massage studios. I did quite well and kept in touch with the instructor, who was a Hollywood Reader - the people that pre-screen submissions to studios. I wrote a screenplay and shopped it around some, getting a call from a VP at Viacom at my job in landscaping. I was completely and totally unprepared for that call and botched it terribly. I kept that bug in the back of my mind for a few years, and later when a company moved me to Utah for a tech job, I ended up hanging on the periphery of the Indie Film crowd. I went to a very professional Short Film Fest in Nevada, and decided I would make one for a Utah fest. The topic of the short was supposed to be something ...
