Tonight was the final performance of Ken Jennings, who has smoked all challengers on 'Jeopardy' (TV game show, for all you non-US folk...) for months winning over $2.5 MILLION dollars in the process.
And I know how he did it.
The average person with above-average intelligence should know the answers to almost 2/3rds of all the questions (give or take a few), but due to the structure of the show most people will not get to answer every question they know.... You have to beat out the other two contestants with the buzzer, so things even out and nobody can practically answer more than 40 ~ 50% of the questions. People could go on runs, but eventually these odds caught up with them.
Jennings beat those odds - but HOW is the key.... When a question comes up, it's displayed on the screen and Alex Trebek reads it out loud. Human nature forces us all to read the question along with Alex! (think about that for a moment), but Ken was able to overcome this.... He could block out Alex and read the question himself visually, and decide if he knew the answer and start clicking on the buzzer before the other two contestants had even finished processing what they were hearing. This allowed him to answer almost every question that he knew the answer to, and run the table for 75 games.
What?!? You think ya got a better theory???
