In my book, I talk about the importance of creating a quiz persona for yourself - allowing yourself to get into the right mode for quizzing.
In Kluge (the book I am currently reading), the author discusses experiments where people who were called 'intellectual' and 'smart' before taking part in an IQ test seriously outperformed people who were insulted with words such as 'dumb' and 'stupid' before taking their tests.
This technique is called 'priming'!
How effective it is for quizzing purposes is something I'm certaily curious about.
And for all the pub quiz players out-there, it might be worth priming your team-mates right before a quiz (yes, that means complimenting one another and praising all your team-mates on the incredible breadth of their general knowledge!)
