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 worry rests on treating an earlier lottery win as the cause of the later pickpocketing.

The two events were merely in sequence: a win, then a theft the next morning.

Mere temporal succession is taken as a causal connection.

Expecting the same theft after this win repeats that unwarranted causal leap.

Inferring cause from after-this-therefore-because-of-this is the post hoc fallacy.
