Cargo Cult Science May Be Causing You To Lose Out On The Truth
The real purpose of the scientific method is to make sure nature has misled you into thinking you know something you don t know. Robert Pirsig
The more I learn, the more I realize how much I don't know. - Albert Einstein
What were covering How important maintaining an objective process & avoiding the destruction cargo cult sciences cause, What is the scientific method, Evolution of my swing experiments (did you visit my http://gohpl.com/swingexperiment link?), and How far I ve come since 11yo swing experiment
A Couple Recurring Cast of Characters Dr. Ben Goldacre: Ben is a best- selling author, broadcaster, campaigner, medical doctor and academic who specializes in unpicking the misuse of science and statistics by journalists, politicians, quacks, drug companies, and more.
A Couple Recurring Cast of Characters Dr. Richard Feynman: American theoretical physicist, worked on Manhattan Project, received the Nobel Prize in Physics in 1965, British journal Physics World said he was ranked as one of the ten greatest physicists of all time, NY Times bestselling book.
Ben Goldacre, Bad Science: Quacks, Hacks, & Big Pharma Flacks
Dr. Ben Goldacre Quote They have never tested an idea for themselves, using their own hands, or seen the results of that test, using their own eyes, and they have never thought carefully about what those results mean for the idea they are testing, using their own brain.
Dr. Richard Feynmans best selling book Surely You re Joking Mr. Feynman
Dr. Feynman On Cargo Cult Science The form is perfect. It looks exactly the way it looked before. But it doesn't work. No airplanes land. So I call these things cargo cult science, because they follow all the apparent precepts and forms of scientific investigation, but they're missing something essential, because the planes don't land.
Dr. Feynman On Maintaining An Objective Nature Paraphrasing: Give people all the facts they need to judge the value of your contribution, not just info that leads to judgment into one outcome or another. Be careful of biases.
What is the Scientific Method? Question Background research Hypothesis Data Collection Data Analysis & Conclusion
Evolution of Swing Experiments 11yo 6th Grade Mike & Joey Experiment (1992) To see what hits the ball farther a wood or metal bat One wood, 2 Metal Bats Used Pitched to each other Looked at between 50-100 batted balls Marked off distances by stepping off each batted ball Got a C on our project :-D
Evolution of Swing Experiments October 2014 Showing numbers v. NOT showing numbers To see which technique increased Bat Speed at Impact, and by how much 100 consecutive swings one way, 100 consecutive swings the other, Breaking the swing into 2-steps Found average 6-mph gain in avg. Bat Speed at Impact by Showing Numbers Problem: didn t counter-balance the swings
Evolution of Swing Experiments August 2015 Don t Buy Expensive Bats Before Testing First Using same company & size metal bat (34/31), testing different models $200 v. $400 200 counter-balanced swings, Zepp & Radar Gun measurements Found $400 bat outperformed on Zepp (2-4 mph), but underperformed on BES readings (4.6- mph) Problem: end loaded v. balanced
How Far Ive Come Since 11yo How to isolate a variable (breaking swing apart), Taking bigger sample sizes, Collecting accurate apples to apples data, Counter-balancing experiment (take out warm-up and getting tired biases
How Far Ive Come Since 11yo How to isolate a variable (breaking swing apart), Taking bigger sample sizes, Collecting accurate apples to apples data, Counter-balancing experiment (take out warm-up and getting tired biases
What We Went Over: How important maintaining an objective process & avoiding the destruction cargo cult sciences cause, What is the scientific method, Evolution of my swing experiments, and How far I ve come since 11yo swing experiment.
