What is a single word for "drawing a decisive conclusion about a phenomenon according to specific personal experience"?
I often encounter people who can follow a pattern like that in an argument:
A: What do you think about the new X cell phone?
B: My sister bought one, and she could not operate it, so it's not user friendly.
It's not only generalization, but also taking a case that you are familiar with and making conclusions about a certain object according to that case even if the conclusion is not relevant or connected.
