Dramatization has nothing to do with credibility. It is a memory facilitation technique. Because you the reader can remove the drama and distill the critical story elements for further inspection of credibility.
Credibility is found in the citations, which here is only the story teller. As that is only one data point, I totally understand doubting its credibility because one needs more citations and voices for proof.
Further, I never stated I found the story creditable. I was operating from a believability standpoint. Inferring one's experience to weight if the story could possibly be believed. You shared you found it hard to believe based on it's dramatization. Where I shared that I found it completely plausible based on my experience.
And that is my main argument, that in this equation drama shouldn't be used as a weight. Positive or negative.
Edit: For the folks down voting this. Please don't conflate dramatization with persuaion, propaganda, or fake news. Dramatization is a tool used in those techniques.
Certainly not. But at the very least, dramatization decreases the credibility of a story.
