This particular fallacy, fallacy of a single cause, can also be referred to as causal oversimplification or the reduction fallacy. The root of this logical fallacy is the assumption that one factor, regarding an issue, is the direct reason behind that issue. This is because of its occurrence before said issue. To simplify, fallacy of a single cause is a fallacy that states: Y occurred then X, therefor Y and only Y is the cause of X.
An example of fallacy of a single cause could be- “President Trump has been in office for a month and gas prices have been skyrocketing. The rise in gas prices is because of President Trump.” As stated, the correlation between the role of President Trump and gas prices is direct; only because of their chronological order and assumed connection.
Some major issues with this fallacy is that it leads no room for actual analytical thought. Instead of accurately determining whether an element is the cause of some outcome, simple chronological order and somewhat connected subjects are enough to say that one unit is the cause of the other. This typically leads to a myriad of false claims and accusations. While there are instances when sequence of events is a direct sign of causation, this is not an absolute rule to go by.
