Abilene Paradox

On a hot afternoon visiting in Coleman, Texas, the family is comfortably playing dominoes on a porch, until the father-in-law suggests that they take a trip to Abilene (a city 53 miles north of Coleman) for dinner. The wife says, “Sounds like a great idea.” The husband, despite having reservations because the drive is long and hot, thinks that his preferences must be out-of-step with the group and says, “Sounds good to me. I just hope your mother wants to go.” The mother-in-law then says, “Of course I want to go. I haven’t been to Abilene in a long time.”

The drive is hot, dusty, and long. When they arrive at the cafeteria, the food is as bad as the drive. They arrive back home four hours later, exhausted. One of them dishonestly says, “It was a great trip, wasn’t it?” The mother-in-law says that, actually, she would rather have stayed home, but went along since the other three were so enthusiastic. The husband says, “I wasn’t delighted to be doing what we were doing. I only went to satisfy the rest of you.” The wife says, “I just went along to keep you happy. I would have had to be crazy to want to go out in the heat like that.” The father-in-law then says that he only suggested it because he thought the others might be bored.

The group sits back, perplexed that they together decided to take a trip which none of them wanted. They each would have preferred to sit comfortably, but did not admit to it when they still had time to enjoy the afternoon.

This anecdote was written by management expert Jerry B. Harvey to elucidate a paradox found in human nature, where a group of people collectively decide on a course of action that is against the best wishes of any individual in the group. Essentially, the group agrees to do something that would not benefit any one, or the group as a whole. This is the Abilene paradox, colloquially known to us through the idiom: “do not rock the boat”.

As seen in the anecdote, there is a breakdown of communication where each member assumes that the majority of the group will decide to follow the action, pushing them towards conformity. There is a mutual mistaken belief that everyone wants the action when no one does, leading to no one raising objections. This is a type of phenomenon called groupthink (coined by George Orwell in his dystopian novel, Nineteen Eighty-Four), where people do not present alternatives or objections, or even voicing their opinions simply because they believe that will ruin the harmony of the group. They are also under peer-pressure, believing that by being the one voice against the unanimous decision they will become ostracised.

The Abilene paradox explains why poor decisions are made by businesses, especially in committees. Because no one objects to a bad idea (falsely believing that that is what the group wants), even bad ideas are accepted unanimously. This is particularly dangerous when combined with cognitive dissonance, where the group will believe that they chose that decision because it was rational and logical. To prevent this paradox from destroying individual creativity in the group, one should always ask other members if they actually agree with the decision or are merely the victims of groupthink.

Conformity

We often see people who criticise others for being “sheeple” – people who blindly conform to the majority and follow someone like sheep do. They protest that as human beings, we have a right and duty to exercise free will, sticking up for one’s own opinions. However, according to an infamous experiment from the 1950’s, we know that human beings are bound by our natural instincts to be social creatures, obeying the collective will of the group we are in.

In 1953, Solomon Asch designed an experiment to study the power of conformity. He told participants that they will be taking part in a vision test with a group of people. They were shown a picture depicting lines of various lengths, asking which line on the right matched the line on the left:

It was a simple task of matching the line to another line of the same length with the answer being blatantly obvious. But as with so many psychological experiments, there was a trick. The group of “participants” were actually in on the experiment other than the one subject. During the experiment, the group would all put their hands up on the blatantly wrong answer instead of the actual correct one. How did this action affect the subject’s answer?

Although it seems clear that the answer is A in the given example, when in a situation where the majority of people put their hands up for “B” or “C”, up to 32% of the subjects gave the incorrect answer. No matter how large the differences were between the sizes of the lines, the results did not change. Although 32% is only a third of the study group, one must bear in mind that this experiment only looked at black-and-white scenarios of lines of different length. If the issue at hand was much more “grey” – such as an ethical dilemma – it can be extrapolated that the person would easily sway and conform to the majority opinion.

The reason for the level of conformity exhibited in the experiment is quite simple: it’s the one who is different that gets left out in the cold.
