Logical Fallacies: Advertisements' Biggest Customer

This would be an example of appeal to authority.
This fallacy is committed when someone of higher authority is referenced and most often quoted, in order for the reader/viewer to be persuaded in the direction of the company. More formally, if person A is not qualified to make reliable claims in subject S, then the argument will be fallacious.

In this specific advertisement, Lucky Strike is trying to lure in customers by saying that this product is recommended by Physicians. This specific logical fallacy very common among modern cigarette ads, and those of the past. In these cases the reasoning is flawed because you can’t just slap an authoritative career on the front of your ad, making a certain claim, without any justification for the claim. When a person falls prey to this fallacy, they are accepting a claim as true without there being adequate evidence to do so.
Since people have a tendency to believe authorities (and there are, in fact, good reasons to accept some claims made by authorities) this fallacy is a fairly common one.

 

This would be an example of a Non Sequitur.

Non Sequitur is the fallacy of offering reasons or conclusions that have no logical connection to the argument stated. In Latin this term translates to “doesn’t follow”. This refers to an argument in which the conclusion does not necessarily follow from the premises. In other words, a logical connection is implied where none exists. In this specific ad it trying to convince consumers to buy and eat more lard. Happiness is generally a desirable thing, so customers will see this, and think, ‘well, I want to be happy, so I’ll feed my family lard!’ Now this is dumb. Happiness has literally 0 connection to lard. 0.
