ABC's John Stossel let's us know that not much has changed in the last 19 years.
To demonstrate that, "20/20" ran an experiment. We asked people to put on blindfolds and then to pick up a red jellybean from one of two plates that held a mixture of red and white jellybeans. We offered $1 to anyone who could pick up a red bean.
Here's the catch: While one plate held 20 jellybeans and the other 100, the plate with 20 beans had a higher percentage of red ones. We put up signs that told people this clearly: "10 percent red" of the small plate and just "7 percent red" of the big plate.
Surprisingly, even with the percentage signs in front of them, a third of the people picked the plate with 100 beans.
What people saw overwhelmed their ability to think abstractly about probability.
That's just painful to read.
