Let’s test your RQ – your rudeness quotient. On a scale of 1= No Problem and 10=Hanging at Dawn Without Benefit of a Trial, rate the following:

• You go to a business lunch and your dining companion puts a BlackBerry on the table and checks it compulsively throughout the meal.
• While you’re conducting a seminar you notice that half the attendees are staring at smartphones and some are working them with their thumbs.
• You’re out on a date and you reach out to grasp your lover’s hand, but there’s a cell phone in it.
• Your wife is discussing resort plans for your second honeymoon. She asks you something important. You ask her to repeat what she said because you were too absorbed checking fantasy baseball scores on your Palm Pre.
• The bored concertgoer beside you is checking his email during a tender pianissimo passage of your favorite symphony.

These vignettes exemplify an evolving crisis in etiquette prompted by a new generation of smartphones and other handheld communication devices. New York Times reporter Alex Williams has chronicled the challenge of holding the social fabric together while gamers, bloggers, tweeters, and email checkers succumb to the temptation, if not the compulsion, to indulge their private pursuits in public.

Obviously your RQ depends on which side of the device you’re on. “A spirited debate about etiquette has broken out” Williams writes. “Traditionalists say the use of BlackBerrys and iPhones in meetings is as gauche as ordering out for pizza. Techno-evangelists insist that to ignore real-time text messages in a need-it-yesterday world is to invite peril.” Like it or not, the field is tilting in the direction of the techno-evangelists. Williams reports that a third of some 5300 workers pulled by a job listings website said “they frequently checked e-mail in meetings.” However, out of those that do, “Nearly 20 percent said they had been castigated for poor manners regarding wireless devices.”

You may be lucky to get away with mere castigation. Employees have been fired when caught using their device frivolously. Business leaders instruct attendees to turn off all electronic devices at meetings on pain of ostracism or worse, and visitors to President Obama’s Oval Office are required to leave their BlackBerrys with his secretary (though its well known the President himself is addicted to his). Fistfights have broken out in theaters over cellphones ringing at critical moments in a performance.

And inappropriate use of a device can be fatal. A growing number of car crashes involved drivers talking on cellphones or looking at text message screens, and these practices are being banned in several states. A fatal train accident in California was traced to the engineer’s being distracted by text messages.

And concentration on the screen of your gadget instead of the eyes of your beloved is wreaking havoc in relationships and can contribute to breaking up. On the other hand, if you’re determined to break up with someone, a cell phone can come in handy. A Malaysian government official notified his wife that he was divorcing her – via cell phone. (An Islamic court overruled him, but nice try, huh?)

You can read both sides of the debate in Mind Your BlackBerry or Mind Your Manners. Then let’s review the score on our RQ quiz. How’d you do?
