Have you ever written or created something, and later realized that it was based on something you had already seen (and was not completely your original work)? It’s probably happened to us all.

Magician and mentalist Derren Brown explains in this short video how subliminal messages may affect us. (I would have embedded the video from YouTube, but embedding for this specific video was disabled.)

Many thanks to the folks at Stuff You Should Know for mentioning this video in their podcast on How Deja Vu Works.
