What you tell a friend about your morning becomes your morning
The saying-is-believing effect: Higgins and Rholes (1978) found that tailoring a message to a listener bends your own memory of the facts. A 2005 replication has the numbers.
Students in a 1978 experiment read a paragraph about a man named Donald, whose behavior could be read kindly or unkindly, and then described him to a listener said to like him or to dislike him. When later asked to recall the original paragraph, they leaned the same way their own description had. Higgins and Rholes (Journal of Experimental Social Psychology, 14, 363-378) named the result the saying-is-believing effect: tailoring a message to an audience’s known attitude bends the teller’s memory of the facts.
The numbers from a close replication
The 1978 paper’s own figures were not available to this writer. A close replication was: Echterhoff, Higgins and Groll (2005, Journal of Personality and Social Psychology, 89, 257-276). Sixty-five undergraduates read six ambiguous passages about a student, Michael, and wrote a message for Armin, who supposedly liked or disliked him. Coders scored messages from -5 to +5. Messages to the fond listener averaged +1.00; to the cold one, -0.86.
Told that Armin had recognized Michael, participants recalled the passages at +0.84 (fond) versus -0.63 (cold), an effect size of d = 1.23.
A morning, by inference
Picture a 6:40 alarm, answered at 7:05, described that evening to a friend as “basically on time.” The friend is the audience, and the sentence is written for them. The effect would predict that the sentence, not the clock, is what stays, though no experiment here measured a morning.
It sits beside what happens to a day in memory generally, which is rebuilt rather than replayed, as Kahneman’s Day Reconstruction work shows. It also adds a wrinkle to who you choose to tell: every audience in these studies had a stated attitude, and a friend known to want good news is that kind of audience.
