Jane Perlez and Eric Schmitt, "Pakistan's spies tied to slaying of a journalist", NYT 7/4/2011:
ISLAMABAD, Pakistan — Obama administration officials believe that Pakistan’s powerful spy agency ordered the killing of a Pakistani journalist who had written scathing reports about the infiltration of militants in the country’s military, according to American officials. […]
The disclosure of the intelligence was made in answer to questions about the possibility of its existence, and was reluctantly confirmed by the two officials. “There is a lot of high-level concern about the murder; no one is too busy not to look at this,” said one.
This is a lovely example of the classic pattern first described by Peter Wason and Shuli Reich, "A Verbal Illusion", The Quarterly Journal of Experimental Psychology 31(4):591-97, 1979.
For a discussion of the Wason/Reich account of these cases, see "No detail too small", 11/27/2009, and "No wug is too dax to be zonged", 11/28/2009. They began with the real-world example "No head injury is too trivial to be ignored". As they observed, it is often remarkably difficult to determine whether examples of this general kind have the correct combination of negations and scalar directions. Some web examples of the "no one is too * (not) to *" variety:
His ideas in this practical book can help us learn to slow down and be with God. No one is too busy not to pray after all.
No one is too busy to cook, and anyone can cook.
As Bishop Pilla began to speak, we were privileged to hear the heart of God. He suggested we come together as a community — as ambassadors of hope — and build a new city, whose hallmarks would be peace and justice. Said Pilla: “No one is too poor not to contribute. No one is too rich not to benefit.”
This parable teaches us that no one is too poor to help others and that true charity is rooted in love and compassion.
I think no one is too stupid to not to be able to find the ingredient.
No one is too stupid to make money in the stock market.
No one is too unimportant not to play a vital role in Cymru's fight for freedom and independence.
And Benedictine hospitality says no-one is too unimportant to be part of the community. 'Let the Guest be treated as Christ,' the Rule says.
No one is too old not to have fun at Circus Circus.
Our DJ will provide fantastic music choices and even think about playing games for adults - no one is too old to have fun!
Coaches are role models and no one is too old not to learn.
We believe that learning is a life-long process and that no one is too old to learn and benefit from research based interventions.
In "Multiplex Negatio Ferblondiat", 7/14/2007, I observed that there are four non-exclusive classes of explanations for such things:
1) People get confused about multiple negatives and/or scalar predicates, etc.
2) The connection between English and modal logic may involve some unexpected ambiguities;
3) Negative concord is alive and well in English (or in UG);
4) Odd things become idioms or at least verbal habits ("could care less"; "fail to miss"; "still unpacked").
