We are irresistibly drawn to FREE offers. To an extent, this makes sense: if you get something FREE, there’s no risk. So why not accept it?
But as Dan Ariely points out in his fascinating book, Predictably Irrational, our obsession with FREE goes beyond the logical. We’ll take FREE options over better, non-free options.
Dan Ariely gives many examples of the power of FREE. I’ll outline just three in this post.
Dr Ariely and his collaborators* set up chocolate stands offering passersby a choice between:
Predictably, most people (73%) opted for the Lindt Truffle.
So they knocked one cent off the price of each, offering:
This tiny change totally reversed the outcome: 69% opted for the free Hershey’s Kiss.
My first thought was, “Oh, people probably just didn’t want to fuss the pocket change.” But Dr Ariely’s team repeated the experiment taking change out of the equation. The results were the same.
On Halloween, Dr Ariely gave trick-or-treaters 3 Hershey’s Kisses. Then, he gave them a chance to make a trade:
All but one subject made the logical choice: trading 2 Kisses for the large Snickers bar gives you much more chocolate overall.
Then Dr Ariely changed the offer:
Logically, you’re much better off taking the first option: give up one Kiss and get the large Snickers. In terms of sheer tonnage, you get much more chocolate that way. But as you probably guessed, test subjects were irresistibly drawn to the FREE offer. 70% made the wrong choice.
“But they were just kids! They don’t know better!” you object? Dan Ariely repeated the experiment with MIT students. Same result.
Years ago, Amazon started offering FREE shipping (with a minimum order, of course). Predictably, sales took off… except in France.
The French division of Amazon, it turned out, had implemented the offer a bit differently. Rather than FREE shipping, they offered “1 Franc” shipping. One Franc was about 20 cents — pretty close to free and a real bargain. But close isn’t good enough, it seems.
When the French changed the offer to FREE, sales exploded just like everywhere else.
There are countless other examples of how people are irrationally attracted to FREE offers. So take a look at your website’s offerings, and see if there isn’t some way you can incorporate “Free” into the mix.
