With more recipients, both real and potential, the influence of rumors has also increased. A recent notorious and typical example concerned a nuclear leak into the sea after an earthquake hit Japan and destroyed a nuclear plant in March 2011. This rumor resulted in Chinese shoppers rushing to supermarkets to purchase salt on the basis that this would protect their health from any fallout.

The salt rumor crisis is only one of the incidents that show what threat rumors pose to social order, especially in modern society with advanced telecommunication technology. That is why it is nicknamed "flames on the tongue": in certain conditions, rumors can have consequences almost beyond imagination.

Thus it is the wish, as well as duty, of the authorities to prevent rumors from emerging and spreading. However, in dealing with rumors, the authorities should be extremely careful and rational.

Rumors are more than misinformation they often contain grains of truth that play to preconceived notions.

In certain circumstances, people hope public affairs could be more in accordance with their interests, so they distort information into rumor toward that direction. In this case, the government should recognize the interest of the people behind the rumors, and promptly correct misconceptions, if any, instead of simply issuing a ban on rumors.

A common conclusion of researchers is that the spread of rumors is often due to the absence of reliable information from the government. In his case study of rumors in the US after the Pearl Harbor attack, Allport found the main cause of the rumor was that the people did not trust the government's report on losses.

Therefore, the most effective way of preventing rumor lies in promoting government transparency and letting more people know the truth, which further requires the government to publish information and ensure its public availability in case of public incidents.

The battle against rumor needs cooperation from the public, too, who are expected to develop a deeper sense of responsibility in using and sharing mass media resources. Living in a society of mass information, everybody can become a victim as well as a participator in transmitting rumors; it is of key importance for the ordinary person to be more rational and confirm his or her received information before forwarding it to more people.

Professional media also should play a bigger role in society, and be responsible for digging out the truth and giving it to a wider audience. Time is of the essence in racing against rumors.

Of course, the ultimate solution to rumors lies in constructing rule of law in society, in which every citizen enjoys freedom of speech without violating the rights and freedom of others. With the rule of law, rumors might still emerge, but they will face legal penalties if they harm other people's rights or even social order.

In both China and abroad, examples of rumormongers being stopped, or even punished by law, have proved the old saying that rumor has shorter legs, especially in a modern society with the rule of law.
