A few common fallacies that you just gotta know

Flaw questions are one of the most common types of Logical Reasoning questions on the LSAT. That’s reason enough to study them thoroughly. Furthermore, the concepts that underlie Flaw questions show up in myriad other questions in the LSAT.

So flawed arguments are a big deal. We’ll have more on the importance of flawed arguments later in the week, but for today we’ll look at a few of the most common logical fallacies you’ll see in Flaw questions and on the LSAT in general. The better you get at spotting these, the easier this cursed test gets.

LSAT Flaws in Real Life: Johnny Football is Johnny Fallacy

If you’re studying for the LSAT, you’ve probably begun to notice that the test loves to ask questions regarding flaws in Logical Reasoning. At first, these flaws can seem somewhat ethereal and abstruse, but in time they will become clearer. One way that I practiced recognizing flaws was by noticing their prevalence in popular culture. This post will focus on the flawed reasoning directed toward a lightning rod figure in pop culture — Johnny Manziel.

Johnny Manziel LSAT Flaw #1: Ad Hominem

Ad Hominem flaws arise when someone attacks the arguer rather than the argument itself. For example, if I said that Donald Trump is wrong about L’Oreal products being superior to other hair care products because he himself has almost no natural hair left (or because he uses Dove products), then I would be guilty committing this type of flawed reasoning.

Toronto Mayor Rob Ford’s LSAT Flaws Will Crack You Up

In case you haven’t heard, Toronto mayor Rob Ford recently admitted to smoking crack. His staffers have gone to the police with concerns about his alcohol abuse, which includes drinking and driving and swilling vodka bottle after vodka bottle in high school parking lots. His driver has been arrested on drug dealing charges. Is Ford going to resign? His answer is an emphatic no. And unless he’s convicted of a crime, there’s nothing anyone can do to remove him from office.

Toronto holds a special place on the LSAT. LSAC is often keen on reminding LSAT test takers that the LSAT is used for Canadian law schools, too. As a result, I’d wager that Toronto is one of the most used names for a variable in the LSAT Logic Games section. We’ll take a look here at some of the flawed logic surrounding Mayor Ford’s situation:

These LSAT Flaws Might Be Aaron Hernandez’s Best Defense

In case you haven’t heard about the investigation surrounding New England Patriots tight end Aaron Hernandez, here’s a quick recap.

Aaron Hernandez and Odin Lloyd, a semipro football player who was dating Hernandez’s girlfriend’s sister, were out drinking one night last week. The two of them, along with two other men, left in Hernandez’s SUV. Later, there were only 3. Lloyd’s body was found a mile from Hernandez’s home the next day. He had been shot, execution style.

Then the investigation began. Police discovered that Hernandez had destroyed his house’s security system, which could have recorded video. Asked to hand over his cell phone, Hernandez complied. But the phone was in pieces.

LSAT in Real Life: The Logical Fallacies of Charles Ramsey

Last week, Charles Ramsey rose to Internet fame with one TV interview following the rescue of three women in Cleveland who had been kidnapped for about a decade. And it was one hell of a TV interview (see below), covering everything from how surprised he was to find kidnapping victims in the house next door to a rather cynical take on race relations in the US — or at least in Cleveland. And as often happens when someone goes from unknown to media darling in so short a time, in the days since he was first on TV we’ve found out some unsavory details from Charles Ramsey’s past.

It turns out that Ramsey was convicted of domestic violence more than 10 years ago. But if we were to try to deny him credit for his recent good deeds on that basis, we’d be committing an ad hominem fallacy, attacking the person rather than the argument.

LSAT Flaws I Experienced on My European Vacation

I recently got back from a three-week European vacation, a trip filled with magic and wonderment and standoffish northern Europeans. It’s a land of picturesque fjords, rugged alps, and an abundance of LSAT logical fallacies.

LSAT logical fallacies such as…

Flying on Ryanair – A Composition LSAT Fallacy

Have you ever flown on Ryanair? It’s the Greyhound of the skies, but without the friendly charm. You get a millimeter of legroom, no free food or drinks, and a crew that consists entirely of surly Eastern European teenagers. Ryanair makes United look like Emirates. How do they get away with treating you like human waste? Well, their fares are incredibly cheap; I flew from Dublin to Oslo on Ryanair, an 800-mile trip, for a mere $14. Sounds amazingly inexpensive, right?

Spend Mother’s Day With Some LSAT Logical Fallacies

This Sunday is the holiday known as Mother’s Day. Mother’s Day 2012 is actually the 98th official Mother’s Day, and its origins stretch long before that. It was originally a holiday for mothers who lost sons in the civil war, and was later broadened to honor all mothers. Soon after it was characterized by the rampant commercialism we all know and love today. In fact, Anna Marie Jarvis, the woman responsible for the holiday’s popularity in America, spent the end of her life campaigning against the bastardization of Mother’s Day. Sending a greeting card is just a way of saying you’re too lazy to actually write a letter, she said. Was she right? Probably. At any rate, she died penniless, having spent her inheritance fighting the greeting cards. The greeting cards won, and the wheel in the sky kept on turning. Anyway.

There’s a lot of fallacious reasoning going on with mothers and Mother’s Day.

Spend the Holiday with Some Presidential LSAT Flaws

It’s Presidents’ Day, which means a day off for the lucky ones among us. Since our business here at Blueprint is the LSAT, it’s also the perfect time to look at some President-related logical fallacies. The official federal holiday is in honor of George Washington’s birthday, but we’ll take a broader look.

Equivocation: Bill Clinton, our 42nd President, famously said, “I did not have sexual relations with that woman.” Now that we know many of the details of his affair with one Monica Lewinsky, it would be easy to call this statement a fantastic lie. We could also say that President Clinton was simply doing what an LSAT flaw question answer choice might call equivocating with respect to a key term.

Down! Set! LSAT Logical Fallacies at the Super Bowl! Hike!

Super Bowl XLVI, also known as “Super Bowl Extra Large Six,” is a mere three days away. You have exactly that much time to fly to Las Vegas and lay down your savings on the Giants, the Patriots, the over, the under, or whether or not Madonna kisses Gisele Bündchen during the halftime show.

By this time next week, the big game will be a thing of the past and the February LSAT will once again engulf your concentration. But there’s no reason we can’t tie the two subjects together.

So throw on your jersey, huddle around, and read these five Super Bowl-themed logical fallacies.
