What happens next? Maybe a snake slithers out from the brush. In this case, the sensory input matches your predictions and you run. Or perhaps no snake is present—the leaves were just rustled by the wind—but you see a snake anyway. That’s affective realism. Now consider the third possibility: there is no snake, and you don’t see a snake. In this case, your visual predictions of a snake are corrected quickly; however, your interoceptive predictions are not.
