It's inductance from the particular (me) to the general case

Since I hate crab, all people hate crab and confronted by a crab meat liker I have no capacity to imagine why, since I hate it and therefore everybody should and therefore you're wrong.

In reality, it's the exception proving (testing) the case and showing it's flaw: all people do not hate crab therefore my generalisation is specious. Instead of doubting why anyone likes crab I should ask why I hate it.
