William Wrigley Jr.,the American chewing gum tycoon,once noted that business is built by men who disagree,and that"When two men always agree,one of them is unnecessary."1,notjust in business but also in politics,sports,and the arts,there is no 2 0f real-world examples of successful partnerships that were fueled as much by the 3 0f ideas as by creative tension or discord.Scientific research shows that creativity and innovation can be 4 by reducing team harmony.For instance,a recent study of 100 product development teams found that two common 5 0f team harmony,namely diversity and task uncertainty,were positively 6 with creative performance.7,a review of theoretical and quantitative studies showed that teams are often more creative 8 they have f ewer rather than more resources.Furthermore,teams that are able t0 9 productive task conflict-expressing disagreements,negotiating between different views,and working under a certain amount of tension 10 to be more innovative,11,when teams and organizations enjoy too much harmony,they will gravitate 12 inaction and complacency,13,as Clayton Christensen noted,will 14 decline and extinction.From Kodak to Blackberry to Blockbuster,business schools are spoiled for choice when it comes to examples of dominant market players that were discarded from the top 15 their complacency.Success and happiness pose a bigger threat to businesses than a moderate 16 0f dissatisfaction.Being happy with the status quo is a 17 way to escape creativity.Any significant innovation in the history of civilization was the 18 of dissatis fied minds:people who were unhappy with the current order of things and 19 to destroy the 20 harmony.

Text3 Brands began as badges of product quality,going back at least as far as the medieval association of craftsmen who used them to distinguish their work.Now in providing consumers with.a host of fascinating facts,companies are striving to grant their brands"authenticity".Interbrand,a consultant on branding,describes authenticity as"an internal truth and capability",a"defined heritage"and a"well-grounded value set".Authenticity is being advertised as a cure for consumers'fading loyalty to brands.It is not hard to see why the old marketing magic is fading,in an age in which people can instantly learn truth about the things they are thinking about buying.Online reviews and friends'comments on social media help consumers see a product's underlying merits and demerits.For brands that lack any truly distinguishing features,that is bad news.The declining faith in brands is a greater threat to some types of products than others:snacks and household gadgets,say,as opposed to luxury handbags.But for a range of consumer goods,brands'strength as a signal of quality,and their power to open people's wallets,are fading,argue Itamar Simonson and Emanuel Rosen in their book,Absolute Value:What Really Influences Customers in the Age of Peifect Information.Surveys back up this conclusion.In North America consumers say they trust only about a fifth of brands,according to a poll by a marketing agency.Consumers seem particularly wary of big brands.About half ofAmerican shoppers say they trust small companies to do the right thing,compared with just 36%who say the same oflarge ones,reports a research firm.These opinions are starting to have effects.Of the top 100 consumers packaged-goods brands in America,90 lost market share in the year to July,according to a marketing firm.In big emerging markets,foreign-branded goods are losing their appeal,as shoppers realise that local products are no longer so inferior.The silver lining to the dark cloud looming over brands is that as people become better informed about products'underlying qualities,and more sceptical of marketing strategies,they are exhibiting a desire for brands that are"honest"and seem to have some identifiable merit.Inevitably,this is leading some marketers to embrace campaigns that seek to bring about the inexpressible quality of authenticity out of thin air.As the cynics among them might say:authenticity is the secret of success;once you fake it,you've got it made.32.Itamar Simonson and Emanuel Rosen point out that
A.brands still have the power to guide customers.
B.people are more loyal to some specific household products.
C.customers ofluxury handbags always have the faith on brands.
D.big companies have greater influence than that of small companies.

Artificial intelligence,or AI,is called artificial for a good reason.Facebook made that point last week by ending its attempt to rely heavily on software algorithms to select news items for its 2 billion users.It announced Jan.19 that the Facebook"community"will be asked to rank news outlets by their trustworthiness.This reader feedback will promote"high quality news that helps build a sense of common ground"in a world with"so much division,"said chief executive Mark Zuckerberg.The first surveys have started in the United States and will soon expand to other countries.The company plans to include the local news outlets of users in its surveys.Like many digital platforms that act as news providers,Facebook had great faith in a belief that programmed electrons in computer servers can discern qualities of thought such as trust,fairness,and honesty.Even in respected newsrooms,however,these traits of character require constant upkeep among journalists and feedback from paying customers.Good judgment on news relies on orders of consciousness beyond what a machine can do.Rather than move toward becoming a hands-on gatekeeper of news,Facebook now hopes its"diverse and representative"sampling of users can lead to a ranking of news outlets-and that would bring a measure of objectivity in its news feed.The company may be in the news business but it has chosen to outsource news credibility to the collective wisdom of individuals and their ability to distinguish truth from falsehood.By placing its trust in people as seekers of truth,Facebook could earn greater trust from its users.This is also a lesson for many companies,especially digital platforms or those in the media business.According to the latest survey of trust in institutions worldwide by Edelman communications firm,"media has become the least-trusted institution for the first time,"more so than other businesses or government.In particular,the US is"enduring an unprecedented crisis of trust"among many of its institutions,says Richard Edelman,president and CEO of Edelman."The root cause of this fall is the lack of objective facts and rational discourse,"he adds.Facebook's shift away from computer-driven news selection is a welcome step toward restoring trust in the overall business of news.This is not a new problem."Nothing can now be believed which is seen in a newspaper,"wrote Thomas Jefferson in 1807.Yet the Digital Age has forced the issue of trust for news providers.By inviting readers to participate in solving this problem,Facebook has itself set a new bar for earning trust.
