"Although I am very happy to win the lottery, I am also a little worried. The last time I had won a lottery, my pocket was picked the next morning." Which logical fallacy is committed in the above argument?

The correct answer is Post hoc.
Key PointsThe phrase "post hoc" is short for "post hoc ergo propter hoc", a Latin phrase which means "after this, therefore because of this."

• This is a type of logical fallacy where one event is assumed to be the cause of a later event simply because it occurred earlier.

In the provided statement: "Although I am very happy to win the lottery, I am also a little worried.

• The last time I had won a lottery, my pocket was picked the next morning," the speaker commits the post hoc fallacy by assuming that winning the lottery directly led to their pocket being picked.
• Just because the speaker's pocket was picked after they won the lottery does not mean that winning the lottery was the cause of the pocket being picked.
• The two events could be entirely unrelated, and without additional evidence, it is fallacious to assume that one caused the other.

Therefore, labeling this as a post hoc fallacy is correct because the speaker is making a causal assumption based on the sequence of events, not based on any demonstrated cause-and-effect relationship.
