Your friends send you a text message of a video with a celebrity talking about an inflammatory topic, but the video seems kind of strange. You can’t quite figure out what it is - the voice sounds legit, the face is legit... but is this the kind of thing that person would say? Is the video legit?

You get an email from your coworker at a really late hour, and it types the same way your coworker types. The message is kind of mangled up but he uses the same words to describe you that he uses in real life. He’s asking you for $100. Is it normal for him to ask for $100?

Remember the one time you saw that grey robot driving down the sidewalk with food on top of it? Now there’s a lot of those, and you’re hungry yourself, and you want to try it, catch is: it can only go deliver it to you if you give it a picture of your house. Would you give a random service that promises to find your house a picture of it for food?
