Fooled at First Sight 

When you think a girl is really hot initially, but then you see other pictures of her that aren't as flattering. Your opinion of this girl deteriorates and you sometimes even question her beauty.

Also can be referred to as Fooled at First Boner.

"I used to think this girl was very hot, but after seeing unflattering Instagram pictures of her, I no longer think much of her in the looks department."

"Seems like you were fooled at first sight."

Fooled by Randomness Theory

The theory, from Taleb's book of the same name, that humans systematically misinterpret random events, seeing patterns where none exist and attributing skill to luck. Fooled by Randomness Theory argues that we are narrative creatures, wired to find stories in noise, to see causes where there are only correlations, to believe we understand what is actually random. Successful traders are often just lucky, not skilled; failed entrepreneurs are often just unlucky, not incompetent. The theory explains why we overestimate our ability to predict, why we trust experts who are actually random, why we build theories on statistical flukes. It's the foundation of skepticism about success stories, about "genius" CEOs, about anyone whose track record could be explained by chance. The theory doesn't deny skill; it insists on distinguishing skill from luck—and shows how bad we are at that distinction.

Example: "The hedge fund manager had ten years of brilliant returns. Fooled by Randomness Theory asked: could this happen by chance? The math said yes—a few funds will always be lucky by pure randomness. The manager was celebrated as a genius until the next ten years revealed the truth: he'd been lucky, not skilled. His investors had been fooled by randomness."

Fooled by Conditions Theory

A framework revealing how we mistake necessary conditions for sufficient causes, or background conditions for foreground explanations. Fooled by Conditions Theory shows how we attribute outcomes to visible causes while ignoring the invisible conditions that made those causes possible. The spark gets credit; the oxygen is forgotten. We are fooled when we focus on triggers and ignore the conditions that make triggers effective.

Fooled by Conditions Theory "The match caused the fire, they said. But the fire needed oxygen, fuel, dryness—conditions that were ignored. Fooled by Conditions: seeing the trigger, missing the context. The match was nothing without the conditions; the conditions were everything, but we never saw them."
