Superstition & Computer Technology

Posted by mattusmaximus on August 27, 2009

Today I saw a great post over at the Tech Republic blog about the “10 habits of superstitious users” of computers.  I wanted to pass this along to you, partially because it is an excellent contemporary example of loose & magical thinking.  I am also sharing it partially out of deference to my wife, who has to deal with the computer illiterate all-too-often who view the computer as either some kind of malevolent entity or a magical box.

Here is the main text of the article [note that I’ve added relevant links to the text]…

Superstition: A belief, not based on human reason or scientific knowledge, that future events may be influenced by one’s behavior in some magical or mystical way (Wiktionary).

In 1947, the psychologist B. F. Skinner reported a series of experiments in which pigeons could push a lever that would randomly either give them a food pellet, or nothing. Think of it as a sort of one-armed bandit that the pigeons played for free. Skinner found, after a while, that some of the pigeons started acting oddly before pushing the lever. One moved in counterclockwise circles, one repeatedly stuck its head into the upper corner of the cage, and two others would swing their heads back and forth in a sort of pendulum motion. He suggested that the birds had developed “superstitious behaviors” by associating getting the food with something they happened to be doing when they actually got it — and they had wrongly concluded that if they did it again, they were more likely to get the pellet. Essentially, they were doing a sort of food-pellet dance to better their odds.

Although computer users are undoubtedly smarter than pigeons, users who really don’t understand how a computer works may also wrongly connect some action of theirs with success (and repeat it), or associate it with failure (and avoid it like the plague). Here are some of the user superstitions I’ve encountered.

More Martian Madness

Posted by mattusmaximus on May 6, 2009

My last entry focused on a supposed “alien” skull found on the surface of Mars, which is really nothing more than a classic case of pareidolia. Well, just today I received a bogus email from a colleague which recycles the old “Mars is going to be closer than EVER!” myth which has propagated over the last few years.

The email reads, in part…

The Red Planet is about to be spectacular! This month and next, Earth is catching up with Mars in an encounter that will culminate in the closest approach between the two planets in recorded history. The next time Mars may come this close is in 2287. Due to the way Jupiter’s gravity tugs on Mars and perturbs its orbit, astronomers can only be certain that Mars has not come this close to Earth in the Last 5,000 years, but it may be as long as 60,000 years before it happens again.

The encounter will culminate on August 27th when Mars comes to within 34,649,589 miles of Earth and will be (next to the moon) the brightest object in the night sky. It will attain a magnitude of -2.9 and will appear 25.11 arc seconds wide. At a modest 75-power magnification Mars will look as large as the full moon to the naked eye. Mars will be easy to spot. At the beginning of August it will rise in the east at 10 p.m. and reach its azimuth at about 3 a.m.

By the end of August when the two planets are closest, Mars will rise at nightfall and reach its highest point in the sky at 12:30 a.m. That’s pretty convenient to see something that no human being has seen in recorded history. So, mark your calendar at the beginning of August to see Mars grow progressively brighter and brighter throughout the month. Share this with your children and grandchildren. NO ONE ALIVE TODAY WILL EVER SEE THIS AGAIN

The Death and Rebirth of Science Reporting?

Posted by mattusmaximus on April 1, 2009

There has been a disturbing trend in recent years in journalistic circles: the decline of science journalism in many areas of the media, specifically print media (newspapers, magazines, etc). However, it’s not all bad news, because Internet-based blogging provides a new venue for science reporting.

As this article in NatureNews states…

Traditional journalists are increasingly looking to such [science-based] sites to find story ideas (see ‘Rise of the blogs’). At the same time, they rely heavily on the public-relations departments of scientific organizations. As newspapers employ fewer people with science-writing backgrounds, these press offices are employing more. Whether directly or indirectly, scientists and the institutions at which they work are having more influence than ever over what the public reads about their work.
