I recently started reading
Robert B. Cialdini's "
Influence: The Psychology of Persuasion" and was struck by an interesting study in the first chapter.
Harvard social psychologist
Ellen Langer conducted a study based on the seemingly built in human response to respond to a favor better when there's a good reason to fulfill the request.
In her study, someone would approach a line of people waiting to use the copier at the library and ask to make copies.
In the first group, the person would say:
"Excuse me, I have five pages. May I use the Xerox machine because I'm in a rush?" An overwhelming large number of people responded favorably (94%) and allowed the person to skip ahead in line.

In the second group, the reason was dropped and the question was changed to:
"Excuse me, I have five pages. May I use the Xerox machine?" In this situation, the positive response dropped significantly to only 60% of those in line letting the person skip ahead.
And, just to test to how important the actual reason was, a third test was conducted, this time again with a reason, but... a useless reason. The reason was a restatement of the obvious:
"Excuse me, I have five pages. May I use the Xerox machine because I need to make copies?"Adding a reason, even though it's an obvious and unnecessary to state reason, brought the positive response back up, this time to 93%.
How can this study can help us real estate investors and marketers?
It can help in two very effective and useful ways.
