How can studying the biography of an all-but-forgotten U.S. president help us think more clearly?
Subject: Thin Slicing - The Warren Harding Effect (Halo Effect)
Event: Publication of Malcolm Gladwell’s Blink, 2005
On January 11, 2005, Malcolm Gladwell published Blink, a book that examines the psychology of quick decision-making. The book includes a fascinating critique of thin-slicing, the cognitive process of drawing broad, swift conclusions based on small bits of specific evidence.
While Gladwell explains that the type of intuitive judgment required for thin-slicing can be developed by experience and training, he also argues that it often leads to erroneous hasty generalizations based on prejudice and stereotypes.
One specific cognitive bias that results from thin-slicing is illustrated by the biography of the 29th president of the United States, Warren G. Harding.
Gladwell explains that there was nothing that distinguished Harding as a great leader or politician. He was not highly intelligent, nor did he have any significant legislative or policy achievements. From the beginning of his
political career at the turn of the 19th century until his successful run for the U.S. presidency in 1921, besides winning elections, Harding accomplished little else. Harding did have one thing that distinguished him, however -- his regal appearance. He was a handsome man with a rich, resonant voice.
As Gladwell explains, it was Harding’s attractive appearance that short-circuited the public’s thinking:
Many people who looked at Warren Harding saw how extraordinarily handsome and distinguished-looking he was and jumped to the immediate -- and entirely unwarranted -- conclusion that he was a man of courage and intelligence and integrity. They didn’t dig below the surface. The way he looked carried so many powerful connotations that it stopped the normal process of thinking dead in its tracks (1).
What Gladwell calls the Warren Harding error is a more specific brand of a broader psychological phenomenon called the halo effect. Anytime we allow a single quality, such as physical attractiveness, social status, or celebrity to overshadow all other qualities, we have fallen for the halo effect. It explains why companies pay star athletes large sums of money to endorse their products. Michael Jordan may not be an expert in car performance, but Chevrolet can count on the halo effect to subconsciously influence consumers. Jordan’s athletic prowess is so prominent that it outshines all other qualities.

Recall, Retrieve, Recite, Ruminate, Reflect, Reason: How can knowing the history of the 29th U.S. president help us avoid the halo effect and help us make better assessments of individuals?

ALSO ON THIS DAY:
January 11, 1918: Today is the birthday of Edward Aloysius Murphy, best known as the man behind Murphy’s Law, which reminds us that, “Anything that can go wrong will go wrong!” Murphy developed his law as an aerospace engineer in 1951, where he assessed U.S. Air Force scientists in California’s Mojave Desert, where they were conducting tests to study the effects of the force of gravity on pilots. To simulate the force of an airplane crash, the project team mounted a rocket sled on a half-mile track. First, the tests were conducted using a dummy, which later was replaced by a chimpanzee. Finally, a physician named Colonel John Paul Stapp volunteered to ride the sled, nicknamed “Gee Whiz,” as it raced over 200 miles per hour across the desert floor and suddenly came to an abrupt stop.

January 11, 1964: On this day the Surgeon General of the United States released the first report linking cigarette smoking with cancer. Acting on the report’s findings, Congress acted, passing The Federal Cigarette Labeling and Advertising Act of 1965, which required cigarette packages to carry the following Surgeon General’s Warning: “Caution: Cigarette Smoking May Be Hazardous to Your Health.’
