How to Get People to Do Things For You

What do you open first when you get the mail?
The handwritten envelope or the computer generated envelope?
Of course you open the handwritten envelope first. After all, how many handwritten envelopes do you see each week? Not too many.
Because you receive fewer handwritten envelopes than you do computer generated, whether you know it or not, you’re tying more value to these personalised letters.
Understanding that personalised and individualised objects – or hints of personalisation – matter a great deal, especially when influencing others, is the topic of today’s essay.
A couple of years ago I started studying various personalised and individualised objects. It turns out I wasn’t the only person who was interested in this influential gold mine.
Randy Garner of Sam Houston State University (Huntsville) did a brilliant series of studies on Post-it Notes and just how influential they are.
Garner knows that marketers and salespeople need people to act. You need people to do stuff you want them to do now. Getting people to comply with anything that requires effort is extremely valuable to you and me.
Write this down: go buy Post-it Notes…TODAY.
Here’s what Garner did.
He found out whether a Post-it Note, with nothing written on it, influences.

Does the Post-it Note really influence?
In Study 1, he sent surveys by mail to a group of 150 professors. They would receive the following:
Group 1 A survey with a Post-it Note attached asking for the return of the completed survey.
Group 2 A survey with the same handwritten message on the cover letter instead of an attached Post-it Note.
Group 3 A survey with cover letter, but no handwritten message.
What happened?
Group 1 Recipients returned in 76% of cases.
Group 2 48%
Group 3 36%
How would you like to double the results you get in pretty much anything you want?
For a number of reasons, the Post-it Note is a goldmine. Garner nailed it before anyone else.
But it goes beyond results; this is about understanding why the Post-it Note works so well. It represents many powerful behavioral triggers all in one little object.
    1. It doesn’t match the environment. The brain hates it.
    2. It gets attention first because of #1.
    3. It is personalized. (Difference between Group 2 and Group 3.)
    4. It is personalized to the point of an afterthought. (Difference between 1 and 2.)
    5. Ultimately, it is one person communicating with another important person. Almost as if it’s a favor or special request.

Is there magic in a little Post-it Note?
Garner has found the goldmine, but wants to see if there is magic in the Post-it Note that we might not be able to explain but regardless would be incredibly valuable.
In Study 2 a blank Post-it Note is attached to one of the groups.
Group 1 A survey with a Post-it Note message.
Group 2 A survey with a blank Post-it Note attached.
Group 3 A survey with no Post-it Note.
The results?
Group 1 (Roughly the same packaging as Group 1 in the first study) 69% returned.
Group 2 43% returned with a blank Post-Ii Note.
Group 3 34% returned with no Post-it Note.
There might be a little magic in the actual Post-it Note, but the reality is… probably not. This is about Identity. The person sending the survey is personally asking me in a special way (not just writing on the survey) to help them out.
Dr Garner could easily have stopped here, but there’s more to this than ultimate compliance.
Does the Post-it Note influence speed of compliance?
In Survey 3, Garner wanted to find out how fast people would get back a follow-up survey if there was a Post-it Note attached. And, how much information would the person being surveyed return with that Post-it Note there vs a group of people with no Post-it Note?
Group 1 64% returned the packet in a SASE (Self Addressed Stamped Envelope).
Group 2 42% returned the packet. (Similar to Study 2 Group 3.)
Group 1 Returned their SASE and survey in an average of about 4 days.
Group 2 Returned their SASE and survey in an average of about 5 1/2 days.
And Group 1 sent significantly more comments and answered other open ended questions with more words than did Group 2.
That’s where most university research stops.
What makes Garner’s special is that he wants to demonstrate whether this only aids compliance in simpler requests, or if the effect carries to more involved tasks.
Does a personalized Post-it Note create even more magic?
Garner sends 90 participants a long survey and 90 a short survey (one half the size).
Each group was subdivided into three smaller groups.
Group A Received a Post-it Note request.
Group B Received a personalized Post-it Note request with the person’s name on it as well as “thank you” and Garner’s initials at the bottom of the sticky note.
Group C Received no Post-it Note.
What happened?
Post-it Note/Personalized Note/No Note
Long Version 40% / 67% / 13%
Short Version 70% / 77% / 33%
It appears that if the task is simple, the simple Post-it Note request needs no further personalisation. The effect is strong and significant in both experimental conditions.
But, when the task is more involved, the personalized note was significantly more effective than the simple standard Post-it Note request.
Use caution: Post-it Note influence is covert influence
In follow-up conversations, recipients often reported either not remembering the Post-it Note or that it wasn’t important to them.
Garner’s research is a landmark series of studies in influence. Subtle influence can cause compliance if you use the correct triggers. And to use the correct triggers means you have to think about what matters in influence.
Influence is power. Pure and simple. Be wise when you implement that power.
