Might put it into a computer program Ideally the program would include all of the available food options their nutritional value and cost and a complete database of my familys tastes each individuals preferences and aversions It would be hard though to sit down and summon all thatinformationoff the top of my head Ive got loads of memories of people grabbing seconds of asparagus or avoiding the string beans But theyre all mixed up and hard to formalize in a comprehensive list The better solution would be to train the model over time entering data every day on what Id bought and cooked and noting the responses of each family member I would also include parameters or constraints I might limit the fruits and vegetables to whats in season and dole out a certain amount of Pop Tarts but only enough to forestall an open rebellion I also would add a number of rules This one likes meat this one likes bread and pasta this one drinks lots of milk and insists on spreading Nutella on everything in sight If I made this work a major priority over many months I might come up with a very good model I would have turned the food management I keep in my head my informal internal model into a formal external one In creating my model Id be extending my power and influence in the world Id be building an automated me that others can implement even when Im not around There would always be mistakes however because models are by their very nature simplifications No model can include all of the real worlds complexity or the nuance of human communication Inevitably some important information gets left out I might have neglected to inform my model that junk food rules are relaxed on birthdays or that raw carrots arepopular than the cooked variety To create a model then we make choices about whats important enough to include simplifying the world into a toy version that can be easily understood and from which we can infer important facts and actions We expect it to handle only one job and accept that it will occasionally act like a clueless machine one with enormous blind spots Sometimes these blind spots dont matter When we ask Google Maps for directions it models the world as a series of roads tunnels and bridges It ignores the buildings because they arent relevant to the task When avionics software guides an airplane it models the wind the speed of the plane and the landing strip below but not the streets tunnels buildings and people A models blind spots reflect the judgments and priorities of its creators While the choices in Google Maps and avionics software appear cut and dried others are farproblematic The value added model in Washington DC schools to return to that example evaluates teachers largely on the basis of students test scores while ignoring how much the teachers engage the students work on specific skills deal with classroom management or help students with personal and family problems Its overly simple sacrificing accuracy and insight for efficiency Yet from the administrators perspective it provides an effective tool to ferret out hundreds of apparently underperforming teachers even at the risk of misreading some of them Here we see that models despite their reputation for impartiality reflect goals and ideology When I removed the possibility of eating Pop Tarts at every meal I was imposing my ideology on the meals model Its something we do without a second thought Our own values and desires influence our choices from the data we choose to collect to the uestions we ask Models are opinions embedded in mathematics Whether or not a model works is also a matter of opinion After all a key component of every model whether formal or informal is its definition of success This is an important point that well return to as we explore the dark world of WMDs In each case we must ask not only who designed the model but also what that person or company is trying to accomplish If the North Korean government built a model for my familys meals for example itmight be optimized to keep us above the threshold of starvation at the lowest cost based on the food stock available Preferences would count for little or nothing By contrast if my kids were creating the model success might feature ice cream at every meal My own model attempts to blend a bit of the North Koreans resource management with the happiness of my kids along with my own priorities of health convenience diversity of experience and sustainability As a result its muchcomplex But it still reflects my own personal reality And a model built for today will work a bit worse tomorrow It will grow stale if its not constantly updated Prices change as do peoples preferences A model built for a six year old wont work for a teenager This is true of internal models as well You can often see troubles when grandparents visit a grandchild they havent seen for a while On their previous visit they gathered data on what the child knows what makes her laugh and what TV show she likes and unconsciously created a model for relating to this particular four year old Upon meeting her a year later they can suffer a few awkward hours because their models are out of date Thomas the Tank Engine it turns out is no longer cool It takes some time to gather new data about the child and adjust their models This is not to say that good models cannot be primitive Some very effective ones hinge on a single variable The most common model for detecting fires in a home or office weighs only one strongly correlated variable the presence of smoke Thats usually enough But modelers run into problemsor subject us to problemswhen they focus models as simple as a smoke alarm on their fellow humans Racism at the individual level can be seen as a predictive model whirring away in billions of human minds around the world It is built from faulty incomplete or generalized data Whether it comes from experience or hearsay the data indicatesthat certain types of people have behaved badly That generates a binary prediction that all people of that race will behave that same way Needless to say racists dont spend a lot of time hunting down reliable data to train their twisted models And once their model morphs into a belief it becomes hardwired It generates poisonous assumptions yet rarely tests them settling instead for data that seems to confirm and fortify them Conseuently racism is the most slovenly of predictive models It is powered by haphazard data gathering and spurious correlations reinforced by institutional ineuities and polluted by confirmation bias

game of a doubleheader Ted Williams had almost single handedly annihilated his team Williams perhaps the Weapons of Epub / games greatest hitter at the time had smashed three home runs and driven home eight The Indians ended up losing to Boudreau had to take action So when Williams came up for the first time in the second game players on the Indians side started moving around of Math Destruction PDF/EPUB Boudreau the shortstop jogged over to where the second baseman would usually stand and the second baseman backed into short of Math Destruction : How ePUB right field The third baseman movedto his left into the shortstops hole It was clear that Boudreau perhaps out of desperation was shifting the entire orientation of of Math Destruction : How ePUB his defense in an attempt to turn Ted Williamss hits into outs In other words he was thinking like a data scientist He had analyzed crude data most of it observational Ted Williams usually hit the ball to right field Then he adjusted And it worked Fielders caughtof Williamss blistering line drives than before though they could do nothing about the home runs sailing over their heads If you go to a major league baseball game today youll see that defenses now treat nearly every player like Ted Williams While Boudreau merely observed where Williams usually hit the ball managers now know precisely where every player has hit every ball over the last week over the last month throughout his career against left handers when he has two strikes and so on Using this historical data they analyze their current situation and calculate the positioning that is associated with the highest probability of success And that sometimes involves moving players far across the field Shifting defenses is only one piece of a much larger uestion What steps can baseball teams take to maximize the probability that theyll win In their hunt for answers baseball statisticians have scrutinized every variable they can uantify and attached it to a value How muchis a double worth than a single When if ever is it worth it to bunt a runner from first to second base The answers to all of these uestions are blended and combined into mathematical models of their sport These are parallel universes of the baseball world each a complex tapestry of probabilities They include every measurable relationship among every one of the sports components from walks to home runs to the players themselves The purpose of the model is to run differentscenarios at every juncture looking for the optimal combinations If the Yankees bring in a right handed pitcher to face Angels slugger Mike Trout as compared to leaving in the current pitcher how muchlikely are they to get him out And how will that affect their overall odds of winning Baseball is an ideal home for predictive mathematical modeling As Michael Lewis wrote in his bestseller Moneyball the sport has attracted data nerds throughout its history In decades past fans would pore over the stats on the back of baseball cards analyzing Carl Yastrzemskis home run patterns or comparing Roger Clemenss and Dwight Goodens strikeout totals But starting in the s serious statisticians started to investigate what these figures along with an avalanche of new ones really meant how they translated into wins and how executives could maximize success with a minimum of dollars Moneyball is now shorthand for any statistical approach in domains long ruled by the gut But baseball represents a healthy case studyand it serves as a useful contrast to the toxic models or WMDs that are popping up in so many areas of our lives Baseball models are fair in part because theyre transparent Everyone has access to the stats and can understandor less how theyre interpreted Yes one teams model might givevalue to home run hitters while another might discount them a bit because sluggers tend to strike out a lot But in either case the numbers of home runs and strikeouts are there for everyone to see Baseball also has statistical rigor Its gurus have an immense data set at hand almost all of it directly related to the performance of players in the game Moreover their data is highly relevant to the outcomes they are trying to predict This may sound obvious but as well see throughout this book the folks building WMDs routinely lack data for the behaviors theyre most interested in So they substitute stand in data or proxies They draw statisticalcorrelations between a persons zip code or language patterns and her potential to pay back a loan or handle a job These correlations are discriminatory and some of them are illegal Baseball models for the most part dont use proxies because they use pertinent inputs like balls strikes and hits Most crucially that data is constantly pouring in with new statistics from an average of twelve or thirteen games arriving daily from April to October Statisticians can compare the results of these games to the predictions of their models and they can see where they were wrong Maybe they predicted that a left handed reliever would give up lots of hits to right handed battersand yet he mowed them down If so the stats team has to tweak their model and also carry out research on why they got it wrong Did the pitchers new screwball affect his statistics Does he pitch better at night Whatever they learn they can feed back into the model refining it Thats how trustworthy models operate They maintain a constant back and forth with whatever in the world theyre trying to understand or predict Conditions change and so must the model Now you may look at the baseball model with its thousands of changing variables and wonder how we could even be comparing it to the model used to evaluate teachers in Washington DC schools In one of them an entire sport is modeled in fastidious detail and updated continuously The other while cloaked in mystery appears to lean heavily on a handful of test results from one year to the next Is that really a model The answer is yes A model after all is nothingthan an abstract representation of some process be it a baseball game an oil companys supply chain a foreign governments actions or a movie theaters attendance Whether its running in a computer program or in our head the model takes what we know and uses it to predict responses in various situations All of us carry thousandsof models in our heads They tell us what to expect and they guide our decisions Heres an informal model I use every day As a mother of three I cook the meals at homemy husband bless his heart cannot remember to put salt in pasta water Each night when I begin to cook a family meal I internally and intuitively model everyones appetite I know that one of my sons loves chicken but hates hamburgers while another will eat only the pasta with extra grated parmesan cheese But I also have to take into account that peoples appetites vary from day to day so a change can catch my model by surprise Theres some unavoidable uncertainty involved The input to my internal cooking model is the information I have about my family the ingredients I have on hand or I know are available and my own energy time and ambition The output is how and what I decide to cook I evaluate the success of a meal by how satisfied my family seems at the end of it how much theyve eaten and how healthy the food was Seeing how well it is received and how much of it is enjoyed allows me to update my model for the next time I cook The updates and adjustments make it what statisticians call a dynamic model Over the years Ive gotten pretty good at making meals for my family Im proud to say But what if my husband and I go away for a week and I want to explain my system to my mom so she can fill in for me Or what if my friend who has kids wants to know my methods Thats when Id start to formalize my model making it muchsystematic and in some sense mathematical And if I were feeling ambitious I.
