The fallacy goes like this.

The drunkard drinks a bottle of tequila with ice on Monday and gets drunk. The drunkard drinks a bottle of vodka with ice on Tuesday and gets drunk. The drunkard drinks a bottle of whiskey with ice on Wednesday and gets drunk. He concludes that the ice got him drunk.

What is the name of this drunk's fallacy?

    It's called inferring causality from correlation. Commented Mar 26 at 23:49

    Correlation does not imply causation, Latin name cum hoc ergo propter hoc ('with this, therefore because of this').

  • @Conifold It would be nice if you could expand on cum hoc ergo propter hoc and why it is a violation of syllogistic logic in a full answer. I promise to give you the green checkmark.

    I don't believe this is a fallacy; rather it is a mere error. Commented Mar 27 at 10:41

    @JD Not really. A fallacy is specifically an error of reasoning. There's no particular theory of mine here. If you assert my cat is a dog then you're not engaging in a fallacy, you're just wrong. Commented Jul 9 at 20:36

To give an official answer, it's the Causation vs. Correlation fallacy.

    Thank you. Why is causation pitted against causality? Isn't causation an object and causality a subject?

    Whoops, you got me there. I meant to type correlation instead of causality, thank you!
