Quizplus · Accepted Answer

Perceptual illusions such as the Müller-Lyer illusion demonstrate that our perception of the world is not an objective representation of reality, but rather a subjective interpretation that is heavily influenced by our expectations and past experiences. The illusion involves lines of equal length appearing to be different lengths due to the addition of arrowheads or other visual cues, which can be seen as either pointing inward or outward. This shows that our brains are constantly trying to make sense of the visual inputs we receive and are prone to making errors in judgment based on our preconceptions and biases.
