Another case of unexamined statistics, this one in a CNN article on how e-mails affect your IQ - the article also mentions the results of a survey on e-mail:
Nine out of 10 people thought colleagues who answered messages during face-to-face meetings were rude, while three out of 10 believed it was not only acceptable, but a sign of diligence and efficiency.
That’s 12 out of 10. Either that, or 2 or 3 out of 10 people believe answering messages during meetings is both rude AND an acceptable sign of diligence. Dubious!
