Don't Get Fooled Again
How to Lie with Statistics
by Darrell Huff
Statistics/Critical Thinking
TL;DR
This book is your ultimate guide to not getting scammed by numbers. It teaches you how to spot rigged samples, dodgy averages, and graphs that lie harder than your ex. You'll learn to question missing data, misleading visuals, and causation vs. correlation so you can flex your critical thinking muscles and call out the BS when you see it. Basically, it's about data literacy for the streets.
Action Items
Next time you see a 'study' or 'poll' on your feed, ask yourself: 'Who TF did they even ask?' If it's just a bunch of gym bros surveying other gym bros about protein, roll your eyes and move on.
When someone throws an 'average' number at you (like 'average salary' or 'average screen time'), ask 'Which average, fam? Mean, median, or mode?' If they can't tell you, assume they're trying to pull a fast one.
Next time an ad screams '50% more effective!', hit them with '50% more effective than WHAT, exactly?' Don't let them get away with half-truths. Demand the full picture.
If your friend says 'I started drinking energy drinks and now I'm getting better grades, so energy drinks make you smarter,' hit them with 'Correlation ain't causation, bro!' Maybe you just started studying more, or sleeping less.

Key Chapter
Chapter - The 'Look How Awesome We Are' Graph (aka The Gee-Whiz Graph)
Ever seen a graph that makes something look way more dramatic than it is? This chapter spills the tea on how charts can be manipulated to make a tiny change look like a massive leap, or vice versa. It's all about messing with the scale on the Y-axis, or even chopping off the bottom to exaggerate differences. Think of it like someone zooming in super close on a tiny pimple to make it look like a mountain. You'll learn to always check the numbers on the axes, not just the pretty lines, so you don't fall for visual trickery. This skill is crucial for decoding news headlines and marketing ploys that want you to react emotionally, not logically.
Key Methods and Approaches
The 'Who's Even In This Group?'
(AKA: The Sample with the Built-in Bias)
Description:
How surveys and studies pick their people in a way that makes the results totally skewed.
Explanation:
Imagine you're trying to figure out if Gen Z likes TikTok, but you only ask people who are already at a TikTok creator convention. Duh, they're gonna say yes! This method is about how people cherry-pick their 'sample' (the group they study) so the outcome is exactly what they want it to be. It's like asking only your rich friends if they think taxes are too high. Of course, they do!
Examples:
A 'study' on coffee consumption habits conducted only at Starbucks drive-thrus.
A political poll taken exclusively from callers to a specific partisan talk radio show.
An online survey about screen time habits advertised only on a gaming forum.
