If you eat a slice of pizza and it tastes bad, what’s your first thought? Is it, “This is a bad slice of pizza?” Or is it, “All pizza is bad?”
It might seem absurd to think that all pizza is bad based on a single slice, but what if it was the first slice of pizza you’d ever had? Or what if it was the second or third slice, but it was really bad, and the first couple had just been mediocre?
Imagine someone thinking that all pizza is bad based on that one slice, and then deciding to Google something like “stories of people hating pizza” in order to see if their suspicions are true. Sure enough, they find some stories of other people hating pizza! Vindication!
Look, here are two truths: You can always find a bad example of something, and “one” is not a statistically significant sample size. Don’t generalize from the worst example you seek out.
