Why Do We Dismiss The Science Of Weather So Easily?



Weather is just as much psychology as it is science. I've written about this several times HERE, HERE, and HERE

 I call it "Behavioral Meteorology".


Most people find it very difficult to grasp the fact that the weather is one big approximation.  Weather should be exact right?  Well, we humans hate probability.  Why? For our minds to grasp probabilities and randomness, we need to be able to handle multiple possible outcomes at once. We all want a forecast that fits a nice and neat one-size-fits-all package.  Weather has many, many outcomes over a large area over a significant period of time. Change the initial weather conditions (humidity, wind flow, frontal position, upper level energy, etc) and you create more uncertainty. Factor in time and the probability becomes significantly higher. We want to visualize a line of showers that moves in at a specific time, stays for a select amount of time and then moves out without fanfare. Unfortunately, rain events especially the hit and miss storms that we’ve had across the area recently rarely behave in this manner.

I'd like to say that I make a forecast whether short or long term with a cold, rational, scientific eye but I don't. I take into account how the general public will react to EVERY word knowing that most selectively perceive the weather to fit their "sphere of reality". I learned that quickly years ago. For all of the simulations, super-computers, highly detailed satellite data, it doesn't matter how exact your forecast is or what scientific reasoning you used in coming to your conclusion, people will ignore the facts and the data that disagree with their perceptions and will "rationalize" what they want and react accordingly. More often than not, the reactions are very critical. Worse still, its accumulative. The more we selectively perceive the weather to fit our negative connotation, the more hyper critical our reaction and the more rigid our bias becomes. Its a vicious circle that feeds on itself.  I’ve notice this change over the last 10-15 years. This is called the Disconfirmation Bias. Its the tendency to accept supportive evidence of a belief uncritically, but to discount evidence that challenges that belief.  

Recently, many have already postulated that this string of 80+ degree warmth is proof that this summer will be warmer than we thought.  Its a classic example of the RECENCY EFFECT: This is the tendency to think that more recent trends and patterns we observe (which are more recent in our minds like our recent mild winters) are a very good representation of the entire period in question. We believe our memories and observations--recent warmth and humidity--are excellent predictors of what the near future will bring.  Throw in the thousands of weather apps out there that claim to provide the forecast for YOUR location along with the laundry list of cognitive biases (some mentioned above) and you have the confluence of many psychological elements that are difficult to overcome with rational discussion.

It all goes back to basic human nature. A good weather narrative or story is desired versus something data/science driven. Nebulous weather data and science makes most of us feel uncomfortable even if the on-air meteorologist has the best of intentions.  Sophisticated computer models of the weather have made some very good “probabilistic” outcomes for weather events and situations.. Yet a level of uncertainty still remains and we humans don’t like it! We try to rationalize the irrational. Our biases quickly dismiss the probabilistic science as irrelevant or at the very worst, an excuse.

Each day, I analyze the science and remember the psychology. How you react when you hear a weather forecast? Do you dismiss the science? How do you handle probability? Do you like hearing an explanation to why the weather does what it does? Do you overly simplify the weather?

Deep thoughts this morning...Hmmmmm.

The Next 5+ Years of MLB Hall of Fame Voting

Under the most basic of circumstances, predicting hall of fame voting of any sort is a futile exercise.  Yet the upcoming 5 years or so of MLB Hall of Fame voting will feature players that played in an era that was anything but "basic" or "normal" when compared to the historical mean.

This crop of retired players who are or soon will be eligible for Hall of Fame consideration played between the early 1990s and mid to late 2000s.  This era is so heavily associated with performance enhancing drugs that some want the statistics for these 10 to 15 years to be either rubber-stamped with asterisks or completely eradicated from all historical record.  Ultra traditionalists go so as far as branding this era as immoral and unethical.  "Purge the inflated numbers like the contagion they are!", some cry.  Anyway, you get the point that this is still fresh in people's minds 7-plus years after mandatory drug testing was implemented.

Which brings me back to the Hall of Fame. Starting next year, more and more players will be on the ballot from the 1990s era.  So here is what I think the voting will look like from 2012 to 2017.  There is nothing scientific about my methodology although I tried to take into account the typical voter's "passionate" viewpoint on the players in question. The only prerequisite is that I started with the Top 10 vote getters in 2011 as the starting list in 2012.  Here is what I came up with along with a few carry-overs from year to year.

You'll notice that I don't have Schilling or Pedro Martinez voted in.  Not because they are not deserving but because they're are other players who I believe will be voted before them.

2012

Barry Larkin    3rd    62.1%    YES
Jack Morris    13th    53.5%    YES

Lee Smith    10th    45.3%    NO
Jeff Bagwell        2nd    41.7%    NO
Tim Raines    5th    37.5%    NO
E. Martinez    3rd    32.9%    NO
Trammell    11th    24.3%    NO
Walker        2nd    20.3%    NO
McGwire    6th    19.8%    NO
Mcgriff        3rd    17.9%    NO

2013

Legitimate hold-overs from 2012 who have a good shot:

Bagwell        YES
Lee Smith    NO

Bonds        NO
Clemens    NO
Piazza        Maybe
Sosa        NO
Schilling        Maybe
Biggio        YES

2014

Legitamate hold-overs from 2013

Schilling    NO
Piazza        Maybe

Maddux        YES
Thomas        YES
Glavine        YES

2015

Legitamate hold-over from 2014

Piazza        Maybe

R. Johnson    YES
P. Martinez     NO

2016

Legitamate hold-over from 2015

A Brief Explanation on NEUTRONS and NUCLEAR POWER

In school, I remember chemistry being easy to comprehend. Not to oversimplify the science but we mixed chemicals which we could smell and see and voila!  You get some totally different compound with hopefully some fire.  After all, what is chemistry class without fire.

Chemistry reactions result as elections change positions with other electrons with other atoms or molecules.  Physics reactions dive deeper.  The world of physics is much harder to conceptualize because the reactions that define this science occur at the level of the atom. In broad terms (not entirely accurate), an atom looks something like this:  Electrons orbiting around a nucleus of protons and electrons.


What is the particle that is responsible for nuclear reactions?  It is called the NEUTRON.  It resides inside the nucleus.  It wasn't discovered in 1932.  By 1942, it was used in the first nuclear chain reaction. Neutrons are very small.  You could fit more than 66 TRILLION NEUTRONS end to end on a meter stick.

The force that holds this ultra-small particle in the center contains billions and billions of times MORE POTENTIAL ENERGY than everyday chemical reactions.  Its even stronger than GRAVITY! This is what makes nuclear power so attractive.  

Our mind has a difficult time quantifying these changes because these reactions don't occur in our macroscopic world we observe each day.  it isn't until the byproducts of these reactions become a danger in our world we live in.  Unfortunately, the potential meltdown of the nuclear reactors in Japan and the explosions on the news have provided the framework for observation and criticism for all of us not familiar with nuclear technology. 

The fuel that is used in nuclear reactions, believe it or not, occurs in nature.  Uranium is a naturally occurring radioactive element.  It exists in several types. Uranium 235 and 238.  The numbers indicate the number of NEUTRONS IN THE NUCLEUS. 

In a nuclear reaction, the uranium is hit with a neutron.  The collision create tremendous amounts of energy, other elements (Krypton-92 and Barium-141) and MORE NEUTRONS which feed the reaction further.


Remember that the amount of Uranium in a power plant is small compared to necessary amount of coal needed to produce the same amount of energy.  One pound of uranium will provide the same amount of energy as burning 1,500 tons of coal. This is why a conversion to nuclear power has been desirable.  Its very efficient.

Natural Satellite behind Manmade Satellite

Thierry Legault, Astrophotographer in Normandy, France took this photo around the time of the lunar eclipse.  If you look close, you can see the International Space Station (manmade satellite) passing in front of the moon (natural satellite).  The ISS passage took only 1/2 of a second.  When you look at the ISS, remember that its more than 200,000 miles away from the moon.  This illustrated how large the moon really is in comparison.

Notice the solar array in the bottom, close-up photo.

The Election, the Economy and the Blame Game

As with the Bush tax cut and $300 Bush rebate checks back in 2001, no one remembers the months leading up to the 2008 election.  As Barry Ritholtz mentions in his post on his website,    

"...Had Al Gore been President from 2000-08 (and controlled Congress), the next GOP President would have flailed him for the recession and crisis bank relentlessly. Hell, the GOP still beats Jimmy Carter like a piñata. Once Obama took office, that was pretty much the last we heard of the Bush recession. The public actually forget who authorized TARP, who bailed out Citibank, BofA, AIG, Fannie Mae, Bear Stearns, etc."  

The tea party movement--while distancing themselves from the Bush years--blame Obama for the failing economy.  Now the shift in power is back to the Republicans in the House establishing a split Congress.  Funny how our memories are short term.  The same people that voted for change this year voted for change 2 years ago with a strong shift back to the Democrats. 

Pivital election years like this one only verified my long standing thoughts on the voting public:  Most people have no idea what REALLY drives the economy and this go-around, what REALLY caused the financial crisis.  No one realizes that the systematic failure of the financial sector and eventually the global economy is beyond any individual person or political party.  We so easily overly simplify the economic issues in 2010 to one or two areas:  taxes and government.  Television and radio ads beat these ideas in our heads.  Yet the seeds of economic destruction that lead us to where we are now reside in deregulation and--at the time, clever--financial engineering.  The environment existed in the 2000s and still exists to this day. It wasn't illegal
but it was hazardous and full of great risk.  As long as Congress is lobbied by the banking industry regardless of who is in power, PROPER and SMART regulation will never be established.  The Consumer Protection Bill was a good start but won't have a huge effect on the overall economy and unemployment.  It might not be next year or 5 years from now but the same problems that got us in this mess will resurface sometime in the future. 

We fail to remember that after the smaller recession in 2000-2001, employment took several years to recover to pre-recession levels.  We want unemployment to fall NOW yet our economic reality dictates otherwise. 

I guarantee that in two years, if the economy is still struggling, the balance of power will shift once again.  The blame in 2008:  The GOP.  The blame now:  The Dems and Obama  The blame in 2012 will shift back to the GOP if unemployment stays high (which it probably will).

Watch it happen.

My Yearly Movie List - 92 and Counting

A few years back, I began to make a list of movies that I hadn't seen.  The list started as a list of current or somewhat current movies going back 4 or 5 years.  Then the list grew to movies I missed in the 1990s then 1980s then classics from earlier than that.  Needless to say, the list grew to more than 300 movies which I have made a point to watch.  Its my cultural duty, right?  (I'm promoting the art of film making. At least that's what I tell my wife)

Even if I average 100 movies a year (which I reached last year), we are still talking more than 3 years to finish the list.   This also doesn't count adding new movies to the list which I do invariably each each year. 

Here is the list so far in no particular order:  The movies in BOLDFACE are recommended flicks

Canadian Water Consumption During Olympics

EPCOR, the water utility company that runs the fountains up in Edmonton, Canada released this graph yesterday. It's water consumption during the Olympic gold medal hockey game, overlaying consumption of the previous day. How much do Canadians love their hockey? A lot.




The first period ends. Time to pee. The second period ends. Time to pee. The third period ends. Time to pee. Consumption goes way down when Canada wins and during the medal ceremony.

Finally, when it's all said and done, the rest of the country can relieve itself, figuratively and literally.

Recent article on the 1918 EL NINO in AMS Bulletin



I usually don't get to issues of the AMS Bulletin until I am knee deep in back issues.  So this morning, I flipped through February's issue and came across an excellent paper on the El Nino of 1918 and its relation to the influenza pandemic and other climate patterns that existed at that time.


Climate teleconnections before 1950 are very difficult to quantify due to the lack of data from that era.  Buoy arrays didn't exist.  Ground based temperature records are not as reliable as you go back to the start of the 20th century.  This paper aims to trace back the record through reanalysis of existing data.

The paper is not long nor is super-technical or filled with equations.

Freakonomics Podcast: "Faking It"

As a supplement to the newest Freakonomics book called "Super Freakonomics", the Freakonomics Podcast on the New York Times website features updated elements from both Freakonomics books and their brand of economic theory applied to brand new societal subjects you've experienced but probably not thought much about.

The newest episode titled "Faking It" focuses on faking it in social situations, politically and religiously.



Its worth a listen.

NEW Video Game Record

If you've ever seen the  movie King of Kong: A Fistfull of Quarters, you will quickly understand why video game records are considered to be--by the ones who strived to break them--hallowed numbers that deserve to be placed on a pedistle with other records in other sports.


We all remember the classic games.  Pac-Man, Frogger, Donkey Kong, Gallaga.  Each one has a place in the minds of the classic gamers from the early 1980s.  Each one has had a record broken in recent years. Yet one game has eluded players for almost 30 years.



Astroids is a simple, shooter game that doesn't have the luster as the popular games mentioned above.  The record which was originally set back in 1982 by Scott Safran at the peak of the first video game boom.  His score of 41,336,440 just fell to John McAllister of Seattle with a score of 41,338,740. 

It took him 58 hours.
