The so-called &#39;expertise bubble&#39; refers to the fact that an expert&#39;s knowledge can only apply directly to a limited amount of matters or to particular situations or settings. 
When they provide insights on a topic in which their expertise bubble overlaps, this leads to the so-called &#39;the expertise sweet spot&#39;. On the contrary, when the gap becomes big, their insights lose value.

The expertise bubble

When living difficult times, people feel the need to know that they are safe and they mostly try to find this safety in the articles they read, the news they listen to and the people they love. 
However, it is also during these times that authors write down less or more well-documented opinions. And this is something you should definitely pay attention to when reading an article.

Articles and their authors
