The Abilene Paradox

Original image

How often has this happened to you: your family gets together for the holidays and ends up doing something -- going out for food, playing some game, going to see a movie -- that nobody actually wants to do? This happened to me over the holidays when my family planned a trip to a local restaurant. We all agreed to go at a certain time, because each of us assumed that everybody else wanted to go. But secretly, nobody wanted to go. We caught the situation at the last minute when somebody piped up and confessed that he didn't particularly want to go out. "Oh, me neither!" we all agreed.

There's a name for this situation, my brother then told us: the Abilene paradox. According to Wikipedia:

The Abilene paradox is a paradox in which a group of people collectively decide on a course of action that is counter to the preferences of any of the individuals in the group. It involves a common breakdown of group communication in which each member mistakenly believes that their own preferences are counter to the group's and do not raise objections.

Of course, in my case somebody did raise an objection -- but there must have been countless instances where we've done something (like seen a particular movie, etc.) which actually none of us particularly wanted to do. Read more about the Abilene paradox after the jump.

More from Wikipedia:

It was observed by management expert Jerry B. Harvey in his article The Abilene Paradox and other Meditations on Management. [Now expanded into a book -Higgins] The name of the phenomenon comes from an anecdote in the article which Harvey uses to elucidate the 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 [53 miles north] 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. 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.

Scientist Asks: Why Do We Weep?

Sometimes we see the tears coming, and sometimes they catch us off guard; we find ourselves weeping without knowing why. It's a personal problem, but it's a scientific one, too: Why do people weep? What purpose does it serve? One expert attempts to answer these questions in a new article in the journal New Ideas in Psychology.

Article author Carlo V. Bellieni is a pediatrician and a bioethicist at Siena University Hospital in Italy. His previous studies have focused on children's emotional well-being and babies' crying and pain. For his latest paper, he examined data and observations on weeping from more than 70 studies and books from researchers stretching back all the way to Charles Darwin.

His conclusion? Weeping is "a complex phenomenon."

For starters, Bellieni writes, weeping is similar to crying, but it's not the same thing. Crying is typically a reaction to pain or anger. It's audible and physical, increasing heart rate, affecting breathing, and contorting the face and body. A crying person's voice changes, and their body makes more stress hormones like adrenaline. And while they don't shed tears, other animals cry, too.

Weeping, on the other hand, appears to be uniquely human. It's what happens when the cup of our emotions runneth over. We cry when we drop a cinderblock on our foot. We weep at funerals, and at weddings.

As Bellieni discovered, there are many theories on how we cry and weep, and where the tears come from. Some researchers have argued that we make tears to return ourselves to the soothing, fluid environment of the womb. Others theorize that our bodies start extruding tears (and snot) to keep our nose and throat from drying out as our breathing intensifies. Darwin's hypothesis was that the tears are a byproduct of scrunching up our faces, including the tear-production glands.

None of these theories seem especially plausible, Bellieni writes. So for now, the answer to the physical question is, "We don't really know."

The emotional and social sides of the weeping equation are slightly more straightforward.

Weeping is a form of releasing intense emotion and physical tension. When we weep, we tell our body that it's okay to relax. This helps us reset our system, so to speak, and move on.

And seeing someone weep makes us want to help them, Bellieni says. Weeping makes other people want to help us. Visible sorrow is an opportunity to strengthen social ties. And among social animals like us, strong bonds mean a better chance of survival.

It's wrong to think of weeping as wimpy or weak, Bellieni says. In fact, it's "a strong behavior with positive effects on health and social interaction."

"In the light of these data," he concludes, "weeping appears to be a primal and important human behavior that deserves more attention."

If You’ve Ever Seen a Ghost, Science May Explain Why

Despite all the reports of ghost sightings (28 percent of Americans report having ghostly encounters), there’s zero evidence to support the presence of supernatural beings among us. Science may not prove the existence of ghosts, but it can help explain why people think they see ghosts in the first place.

In this video from Vox, paranormal investigator Joe Nickell identifies some of the phenomena believers may mistake for paranormal activity. One possible explanation is infrasound, or the sound waves that fall beneath levels of human perception. Though we can’t hear these noises firsthand, our bodies sense them in other ways. This can cause chills, feelings of unease and depression, and even hallucinations.

Other contributors may include sleep paralysis (when you wake up while your body is immobile and experience waking nightmares) and grief. There are also a few less common possibilities that aren’t covered in the video below: Mold poisoning, for instance, can lead to irrational fear and dementia. Suddenly, a visit from a poltergeist doesn’t sound so scary.
