Answer and Explanation:
1. Because the extreme interest gives the feeling of collecting information, that is, when a person has a very high interest in their business and without reason, it passes the information that they are trying to capture information about you and your business, in general . This information can reveal things you don't want, or it can make you vulnerable to that person, who can plot something to destroy you. This creates distrust.
2. The rumor makes a community believe an unrealistic and negative story about something or someone that is real. This generates fear in a community, as it can cause everyone to be afraid that the negative results of this rumor will afflict them. In this way, the community will try, in vain, to eliminate the source of the rumor, but since it does not exist, they will not succeed and will be terrified and obsessed with getting rid of it, thus causing hysteria.
