Brain Quote by Lisa Feldman Barrett
““I’ve said several times that the brain acts like a scientist. It forms hypotheses through prediction and tests them against the “data” of sensory input. It corrects its predictions by way of prediction error, like a scientist adjusts his or her hypotheses in the face of contrary evidence. When the brain’s predictions match the sensory input, this constitutes a model of the world in that instant, just like a scientist judges that a correct hypothesis is the path to scientific certainty.””

![“A scientist sounds like a scientist because the things that come out of their mouth don't stumble, that's all. If they [said], "And the, um, a microwave, uh," you know, then you don't sound right, but if you can just get it out without stumbling then you're going to sound fine.” quote by Morgan Freeman](https://sms4smile.com/quotes/img-quotes/52a/morgan-freeman-1202_fine_a-scientist-sounds-like-a-scientist-beca_889672.jpg)
