If a baseball and a bat cost $1.10 together, and the bat costs $1.00 more than the ball, how much does the ball cost?
Solution
5 cents. System 1 thinking often leads to mistakes in this type of problem.
A father and son are in a horrible car crash that kills the dad. The son is rushed to the hospital; just as he’s about to go under the knife, the surgeon says, “I can’t operate—that boy is my son!” How is that possible?

In the Oscar-nominated movie ‘The Martian’ Matt Damon plays a NASA botanist stuck on Mars. His crew have departed as they have (reasonably) assumed he has been killed by an accident during their mission.
Damon survives, and wakes up to the magnitude of his situation. It will be several years before a rescue mission can reach him – but he only has sufficient supplies to last a few months.
But as a highly-qualified scientist, he does not panic. Nor does he give up and accept his fate. He decides to solve the problem in the most effective way possible.
In his own words – he decides to “science the sh*t” out of the problem.
He consults the notes left behind by his colleagues, and experiments using the limited resources at his disposal (including a highly creative way of growing potatoes). And keeps himself alive.
Not only is it a great movie, but it’s a metaphor for the way science has solved problems in the world we live. The houses we live in, the food we eat, the transport we use. All of these things were developed by scientists using the scientific method.
A hypothesis, followed by a deduction, and tested through observation. Then repeat.
And yet… why is so little work in the communications industry scientifically based, with little to no experimentation?
