A four-panel xkcd comic strip about good science. Stick figures are shown interacting in a classroom or similar setting.
Transcript:
Panel 1:
I'M SUPPOSED TO GIVE YOU THE TOOLS TO DO GOOD SCIENCE.
[A stick figure stands next to a list on a podium.]
Panel 2:
BUT WHAT ARE THOSE TOOLS?
METHODOLOGY IS HARD AND THERE ARE SO MANY WAYS TO GET INCORRECT RESULTS.
WHAT IS THE MAGIC INGREDIENT THAT MAKES FOR GOOD SCIENCE?
[A teacher figure stands in front of two students sitting at desks.]
Panel 3:
TO FIGURE IT OUT, I RAN A REGRESSION WITH ALL THE FACTORS PEOPLE SAY ARE IMPORTANT:
OUTCOME VARIABLE:
• CORRECT SCIENTIFIC RESULTS
PREDICTORS:
• COLLABORATION
• SKEPTICISM OF OTHERS' CLAIMS
• QUESTIONING YOUR OWN BELIEFS
• TRYING TO FALSIFY HYPOTHESES
• CHECKING CITATIONS
• STATISTICAL RIGOR
• BLINDED ANALYSIS
• FINANCIAL DISCLOSURE
• OPEN DATA
[A student's head is shown looking at a list.]
Panel 4:
THE REGRESSION SAYS TWO INGREDIENTS ARE THE MOST CRUCIAL:
1) GENUINE CURIOSITY ABOUT THE ANSWER TO A QUESTION, AND
2) AMMONIUM HYDROXIDE
WAIT, WHY DID AMMONIA SCORE SO HIGH? HOW DID IT EVEN GET ON THE LIST?
...AND NOW YOU'RE DOING GOOD SCIENCE!
