With the festive season in full swing, many of us will soon find ourselves sitting around a dinner table, tugging on a Christmas cracker then poring over the goodies found within.
Traditionally, cracker etiquette dictates that the person left holding the larger portion is dubbed the cracker king (with flimsy paper crown to prove it).
However, have you ever wondered what ‘cracker strategy’ you should employ to increase your chance of securing the win and looking like one of the Wise Men?
Naturally, our researchers Emma Huang and David Clifford along with their equally-festive colleague from the University of Queensland Kim-Anh le Cao, were wondering the same thing. So they turned to science to find out.
Firstly, they got cracking on identifying three cracking cracker-pulling techniques:
- The ‘angle’ strategy: A firm two handed grip, tilting the cracker between 20 and 55 degrees downwards, and applying a steady force with no torque
- The ‘passive aggressive’ strategy: a firm two handed grip at no angle, no pulling at all, and letting the other person do the work
- The ‘control’ strategy: typical of Christmas parties around the world, where both participants pull at no particular angle, but roughly parallel to the floor
In this festive study, volunteers were randomly paired, employing different strategies multiple times in order to leave us with robust data about the validity of each technique.
So, what were the results?
If you’re an angler, we’ve got bad news. With just a 40 per cent win rate, this technique isn’t likely to secure your spot as cracker king anytime soon. The traditional ‘control approach’ produced the results closest to random chance, resulting in a win 53 per cent of the time.
For those saying bah-humbug to the passive aggressive approach, you might want to rethink things. With an impressive 92 per cent success rate, it turns out the key to securing the win is to let your partner do all the hard work.
As our researchers describe in their study, the passivity of this approach could have important implications for future Christmas parties. Aside from the obvious reduction in cracker-related injuries, the strategy has another major benefit – it is easy to employ with subtlety, unlike strategies involving an angle, which must surely arouse suspicions in your pulling partner.
While we wish you well on your cracker journey, we’ll leave you with a word of caution – while the ‘do nothing’ approach does have a high success rate, it only works if you’re the only one who knows about it. If both you and your partner employ the same strategy, the party could stretch on forever, resulting in a burnt dinner and no paper crown for you.
