Why aren't you curious about what happened?A."you suspended ray rice after our video, a reporter from tmz challenged national football League commissioner roger goodell the other day. "why didn't you have the curosity to go to the casino(5)yourself? "the implication of the question is that a more curious.B.the accusation of incuriosity is one that we hear often carying the suggestion that there is something wrong with not wanting to search out the truth. " have been bothered for a long time about the curious lack of curiosity, "said a democratic member of the new jersey legislature back in july, referring to an insufficiently inquiring attitude on the part of an the george washington bridge traffic scandal " the mainstream media the least curious about what happened? "wrote conservative writer jennifer rubin earlier this year terring to the attack on americans in benghazi, Libya.C.the implication, in each case is that curiosity is a good thing,and a lack of curiosity is a problem are such accusations simply efforts to score political points for one's party? or is here something of particular value about curiosity in and of itself.D.the journalist lan leslie. in his new and enjoyable book curious: the desire to know and whyYour fatter depends on it, insists that the answer to that last question is yes. Leslie argues that curiosity is a much-overlooked human virtue, crucial to our success, and that we are losing it.E.we are suffering. he writes from a" deficit" the word""was coined by horace walpole in an 1854 letter from a tale of three princes whowere always making,discoveries by accident, of things they were not in search of, " worries that the rise of the intemet, among other social and technological changes, has reduced our appetite for aimless adventures no longer have we the inclination to let ourselves wander through tields of knowledges, ready to be surprised. instead, we seek only the information we want.F.why is this a problem because without curiosity we will lose the spirit of innovation and entrepreneurship. we will see unimaginative govemments and dying corporations make disas-trous decisions.We will lose a vital part of what has made humanity as a whole so successful as a species.G.leslie presents considerable evidence for the proposition that the society as a whole is growing less curious.In the U.S and Europe,for example,the rise of the internet has led to a declining consumption of news from outside the reader's borders.But not everything is to be blamed on techeology.The decline in interest in literary fiction is also one of the causes identified by Leslie.Reading literary fiction,he says,make us more curious.H.Moreover,in order to be curious,"you have to be aware of a gap in your knowledge in the first place."although leslie perhaps paints a bit broadly in contending that most of us are unaware of how much we don't know he's surely right to point out that the problem is growing: "Google can give us the powerful illusion that all questions have definite answers.I)Indeed, Google, for which leslie expresses admiration,is also his frequent whipping body(替罪羊).he quotes Google co-founder larry page to the effect that theperfect search engine willunderstand exactly what i mean and give me back exactly what i want "elsewhere in the book,leslie weites:"google aims to save you from the thirst of curiosity altogether.J.Somewhat nostalgically(怀旧地).he quotes john maynard keynes's justly famous words of praise to the bookstore: "one should enter it vaguely, almost in a dream, and allow what is there freely to attract and influence the eye to walk the rounds of the bookshops, dipping curiosity dictates, should be an afternoons entertainment. "if only!K.Citing the work of psychologists and cognitive(认知的)scientists, lesliecriticizes the re-ceived wisdom that academic success is the result of a combination of intellectual talent and hard work. curiosity,he argues, is the third key factor--and a difficult one to preserve,if not cultivated, it will not survive "childhood curiosity is a collaboration between child The surest way to kill it is to leave it alone.L.School education, he wams,is often conducted in a way that makes children incurious chil-dren of educated and upper-middle-class parents turn out to be far more curious,even at early ages than children of working class and lower class families that lack of curiosity produces arelative lack of knowledge,and the lack of knowledge is difficult if not impossible to compen. sate for later on.M)although leslie's book isn't about politics,he doesn't entirely toast cucial moments. there are serious consequence,be ba i 2 Political leaders, like leaders of other organizations,should betheTheyare serious conesquences.he warns, in not wanting to know.N.he presents as an example the failure of the george w bush administration to prepare prop-erly for the after-effects of the invasion of iraq. according to leslie,those who ridiculed former.Defense secretary donald rumsfeld for his 2002 remark that we have to be wary of the un-known unknownswere mistaken.rumsfeld's idea leslie writes," absurd- it was smart."he adds,"the tragedy is that he didn't follow his own advice."O.All of which brings us back to goodell and the christie case and benghazi. each critic in those curious.i leave it to the reader's political preference to decide which,if any charges should remaining determinedly incurious about our own. we should be delighted to pursue knowledge for its own sake--even when what we find out is something we didn't particularly want to.
political leaders' lack of curiosity will result in bad consequences.
