Sometimes free isn't the best deal you can get

" During WWII, statistician Abraham Wald was asked to help the British decide where to add armor to their bombers. After analyzing the records, he recommended adding more armor to the places where there was no damage! The RAF was initially confused.Wald had data only on the planes that returned to Britain so the bullet holes that Wald saw were all in places where a plane could be hit and still survive. The planes that were shot down were probably hit in different places than those that returned so Wald recommended adding armor to the places where the surviving planes were lucky enough not to have been hit.

" I know of a couple who had puppies to give away and no takers. They changed the ad in the paper to read "Free puppies. Five cute / one ugly." They were all adopted the next day by people coming to get the poor ugly puppy. "

" I once read a story about someone who was looking to get rid of an old television set that they didn't want anymore so they put it out by the curb with a sign that said "free TV". People would walk by, give it a quick glance, and keep on walking. "What is going on here, don't people want a free TV," The guy asking himself. Then, he had a brilliant idea. He changed the sign to say, "TV $20.00 or best offer. Inquire inside". It was stolen within a minute. What's counter intuitive? Sometimes free isn't the best deal you can get. "
