For decades, a social psychologist named John Bargh has conducted studies on the way words affect behavior. In one such study, undergraduate students were given a scrambled-sentence test. One version of the test was sprinkled with rude words like “disturb,” “bother,” and “intrude.” Another version was sprinkled with polite words like “respect,” “considerate,” and “yield.” The subjects thought they were taking tests measuring lan­guage ability, but they were actually being subconsciously primed by those words.

Priming is a psychological phenomenon related to stimulus and response, and words are the lead actors. The word “nurse” is recognized more quickly if it’s preceded by the word “doctor.” The same goes for “dog” and “wolf.” Why? These words are semantic primes that cause you to think in categories. If I say Empire State Building, it puts you in a New York state of mind. In the same sense, the word “please” is a politeness prime.

After taking the five-minute scrambled-sentence test, stu­dents were supposed to walk down the hall and talk to the person running the experiment about their next assignment. However, an actor was strategically engaged in conversation with the researcher when the students arrived. The goal? Psychologist Bargh wanted to see whether the subjects who were primed with polite words would wait longer before interrupting than those who were primed with rude words.

The result? Sixty-five percent of the group primed with rude words interrupted the conversation. Those primed with polite words? Eighty-two percent of them never interrupted at all. If the test hadn't timed out at ten minutes, who knows how long they would have waited?

Possible Preaching Angle:

A few polite words. What difference do they make? In quantitative terms, they can make a 47% difference. Don’t underestimate the power of polite words.
