Hi Just taught the working backwards heuristic in cognitive using the example of a tennis tournament. But given it is March Madness time, basketball would have been a better example ... with 64 teams, how many games are necessary? Going to the online brackets, easy to enumerate all the games ... 15 for each grouping of 16 teams x 4 = 60, plus 2 for final four, plus 1 for final = 63 games.
Pause in lecture to ask if there is a faster way to figure it out .... Using the working backward heuristic, there is one winner and 63 losers, hence 63 games are necessary. And if teaching probability, the p for predicting every game by chance is .5^63. What if you always picked the higher ranked team?
