The easiest lie to fall for is an incomplete truth.
Take a picture of a rainbow. Zoom in on the red part. Then show that zoomed shot to someone and say “this is a picture of a rainbow.” It’s true! You haven’t lied! But you’ve given people – quite intentionally, I might add – the impression that rainbows are all or mostly red.
This is what’s happening to you pretty much every second of every day. Every time you receive information, at least.
Context is hard! And when you don’t have it, you extrapolate and assume and you do that in exactly the way the person sharing the information wants you to. People can do this to you without every saying a single lie.
