Summary:

- This article discusses five surprising ideas from the field of cognitive science, which is the study of how the human mind and brain work.

- One idea is that our memory is not as reliable as we think, and we often remember things differently than how they actually happened. This is called the "misinformation effect."

- Another idea is that our brains are constantly making predictions about the world around us, and these predictions can influence what we actually perceive. This is called the "predictive processing" theory.
