I was listening to a great story earlier this\u00a0week on NPR which described an interesting experiment:<\/p>\n
In his book How We Decide<\/em>, and in a recent Wall Street Journal<\/em> article, Jonah Lehrer writes about an experiment by Stanford University professor Baba Shiv, who collected several dozen undergraduates and divided them into two groups.<\/p>\n
In the WSJ<\/em> article, Jonah writes: “One group was given a two-digit number to remember, while the second group was given a seven-digit number. Then they were told to walk down the hall, where they were presented with two different snack options: a slice of chocolate cake or a bowl of fruit salad.”<\/p>\n
And then he writes:<\/p>\n
“Here\u2019s where the results get weird.<\/p><\/blockquote>\n
<\/p>\n
“The students with seven digits to remember were nearly twice as likely to choose the cake as students given two digits. The reason, according to Professor Shiv, is that those extra numbers took up valuable space in the brain \u2014 they were a \u201ccognitive load\u201d \u2014 making it that much harder to resist a decadent dessert. In other words, willpower is so weak, and the prefrontal cortex is so overtaxed, that all it takes is five extra bits of information before the brain starts to give in to temptation.”<\/p>\n
It turns out, Jonah explains, that the part of our brain that is most reasonable, rational and do-the-right-thing is easily toppled by the pull of raw sensual appetite, the lure of sweet. Knowing something is the right thing to do takes work \u2014 brain work \u2014 and our brains aren\u2019t always up to that. The experiment, after all, tells us brains can\u2019t even hold more than seven numbers at a time. Add five extra digits, and good sense tiptoes out of your head, and in comes the cake. “This helps explain why, after a long day at the office, we\u2019re more likely to indulge in a pint of ice cream, or eat one too many slices of leftover pizza,” Lehrer writes.<\/p><\/blockquote>\n
First of all, I totally get it. I had a very busy day yesterday with too much going on in my brain, came home to freshly baked chocolate chip cookies from my boys, and four warm fabulous cookies later realized that the diet for the day was a lost cause!<\/p>\n
More importantly, I think this also explains why emotions bubble up so regularly in negotiations. We might think about all of the information rationally and organize ourselves and be completely ready for the negotiation but \u2013 once we are at the table and keeping track of all of that important information (like memorizing at least\u00a0seven numbers) we are on cognitive overload \u2013 we have a hard time keeping down the\u00a0 “emotional”\u00a0side of our brain. And our impulses, to respond inelegantly, to assume the worst, or to yell, are much more likely to rise to the surface. Perhaps if we show up with warm cookies for all . . . .<\/p>\n
