Texas Sharpshooter: Painting the Target After You Shoot
Finding a pattern in data you’ve already seen isn’t prediction The story goes like this. A Texas sharpshooter fires a bunch of rounds at the side of a barn, then walks over and paints a target around wherever the bullet holes clustered thickest. “Look how accurate I am.” That’s the fallacy. Finding a pattern after…
Cherry Picking
Selecting only the evidence that supports your conclusion Climate change deniers love to point to cold winters. “Record snowfall. So much for global warming.” They’re ignoring the global temperature trends, the melting ice caps, the shifting growing seasons, the increasing frequency of extreme weather events. They found one data point that fits their position and…
Anecdotal Evidence
One person’s experience is real - but it’s not data “I know someone who smoked a pack a day until 97 and never got cancer. So how bad can it really be?” This is how the anecdotal evidence fallacy works. One vivid, concrete personal story gets set against decades of epidemiological research covering millions of…
Hasty Generalization
Three examples do not a universal truth make Somebody says they won’t hire anyone under 25 because “young people don’t want to work.” Asked how many young people they’ve actually interviewed, the answer is three. Three people out of roughly forty million Americans in that age range. This is hasty generalization. Drawing a broad conclusion…
Appeal to Nature
Arsenic is natural. Vaccines aren’t. Choose accordingly. “Chemical-free.” “All-natural ingredients.” “The way nature intended.” These phrases sell billions of dollars of products every year. They work because somewhere in human cognition there’s a deep equation - natural equals safe, synthetic equals dangerous. It’s intuitive. It feels true. People have been trained by marketing to read…
Appeal to Novelty
New doesn’t mean better - it means unproven Appeal to tradition says this is old, therefore it’s good. Appeal to novelty says the exact opposite - this is new, therefore it’s better. Both are wrong for the same reason. Age tells you nothing about quality, whether that age is long or short. A practice can…
Appeal to Tradition
Just because we’ve always done it doesn’t mean we should keep doing it “We’ve always done it this way.” Four of the most dangerous words in policy, business, and everyday life. Not because tradition is always wrong. Plenty of old practices exist because they work. The problem is that “we’ve always done it this way”…
Bandwagon (Appeal to Popularity)
Millions of people have been catastrophically wrong before At some point in human history, the majority of people believed the earth was flat. The majority believed slavery was acceptable. The majority believed women shouldn’t vote. The majority was wrong every single time. This is the core problem with the bandwagon fallacy - also called appeal…
Complex Question
Questions that bury assumptions you haven’t agreed to Somebody asks - “now that you’ve admitted the policy failed, what’s your plan to fix it?” You never admitted it failed. But the question assumes you did and moves straight to demanding your plan. If you answer the second part of the question, you’ve implicitly accepted the…
Loaded Question
Questions that trap you by hiding their assumptions “Have you stopped beating your wife?” Yes or no, you’re trapped. Say yes, and you’ve admitted you used to beat her. Say no, and you’re admitting you still do. The question only works if you first accept the assumption that you beat her in the first place…
Begging the Question (Circular Reasoning)
When your argument assumes what it’s trying to prove “The Bible is true because it says so in the Bible.” That sentence is the clearest possible example of begging the question. Once somebody sees it, they start seeing this structure everywhere, and it turns out a surprising amount of everyday argument is built on exactly…
