Explain how sociology can help differentiate between authentic and fake news. Use a current example to support your argument

The correct answer to this open question is the following.

Sociology can help differentiate between authentic and fake news in the following way.

Sociology studies society and its members in a scientific way. There is a lot of research on this subject. So sociological studies can reveal the motives of groups and members of society when they provide news that is distorted or have a particular agenda, what today is referred to as fake news.

For instance, if an extremist or supremacist group publishes hate messages or racial messages in its web site or social media page in order to support the interest of this group or a politician that supports this group, but it is not supported with solid arguments or facts, then it is fake news.

As the old quote says, a lie repeated two or three times without correction, can become a truth.  

When sociology studies these groups, it can reveal its intention, background, style, and purposes, so people can really identify its true nature.
